Skiathos is not a secret. It has an airport taking direct charter flights from Britain and northern Europe all summer, sixty-plus beaches, and a main town whose nightlife reputation is decades old. That reputation is mostly accurate. But reducing Skiathos to a party island misses most of what makes it exceptional, and so does the opposite mistake, which is reducing it to a boat trip.
The north coast is wild and largely unreachable by land, its beaches, caves and the ghost village of Kastro visible only from the sea. The boat scene that serves it is genuinely good, from forty-person caiques down to two-person kayaks. But the island also has a monastery where the first Greek flag was woven in 1807, a walking network of marked mule paths nobody arriving on a charter flight knows about, and a town that turns out to be the best part of most people's week. Skopelos, greener and quieter, is ninety minutes away by boat.
We have picked what is actually worth your time across all of it, water and land, and said plainly what each thing costs and how you get there without a car. This guide is written with four other Greeks who work in tourism here: a tour operator, a hotelier, a transfer specialist and a Northern Greece supplier.
The GYG marketplace for Skiathos is active and well-populated, reflecting years of organised tourism. The boat tours in particular are numerous and well-reviewed. We have selected the best across categories.

Skiathos Town, After the Beach Closes
Type: Town, museums, sunset viewpoint, nightlife, shopping
Time needed: An afternoon and an evening, and you will still come back
Access: Walkable end to end; bus stop 0 is the port
Cost: Free to wander; Bourtzi museum and the Papadiamantis house are a couple of euros each
Best time: From about six in the evening, when the heat drops and the town fills up
Almost every Skiathos guide sends you straight to the water. That is a mistake you will only notice on your third evening, when you realise the town has been the best part of the day all week.
Start in Plakes, the old quarter climbing the hill behind the Old Port. It is a knot of pedestrian lanes, whitewashed walls, bougainvillea and cats, and it is where people actually live rather than a preserved set. Work upward and you will come out at Agios Nikolaos, the church with the clock tower. The terrace in front is the best free view on the island: red rooftops, both ports, Bourtzi below you and Tsougria out in the bay. It is also the view in the opening sequence of Mamma Mia, where Sophie writes the three invitations.
The rest of the film's locations, from the Old Port to the chapel on Skopelos, are mapped in our Mamma Mia island guide.
Bourtzi is the pine-covered peninsula splitting the harbour into Old Port and New. The Gizi brothers fortified it in 1207 under Venetian rule, it spent time as a quarantine station, and a school was built on it in 1906. That school is now the Museum of Naval and Cultural Tradition, and the cafe at the tip is where to be twenty minutes before sunset. There are steps down to the rocks if you want a swim first.
Alexandros Papadiamantis is the island's most famous son and the reason both the airport and the main street carry his name. He was born here in 1851, wrote more than 180 short stories, and came home to die in 1911. His two-storey family house is a small museum with original furniture on the first floor and a library of manuscripts below. Twenty minutes, and it tells you more about nineteenth-century island life than any amount of coastline.
Then there is the open-air cinema on Papadiamanti Street, which shows Mamma Mia through the season to a crowd that sings along. Book ahead. It is the single most enjoyable evening on Skiathos and it costs less than a boat trip.
After dark the main street and the lanes off it fill with bars that stay busy until very late. The reputation is earned, but it is concentrated: walk five minutes uphill into Plakes and it is silent again.
Good to know: the last bus back from town runs after midnight in high season, which makes a night in town workable even if you are staying out at Koukounaries. Museum opening hours shorten sharply outside July and August. Confirm current museum entry prices before you go, as these change season to season.
Best for: Everyone, on at least two evenings. Non-negotiable for anyone who thinks Skiathos is only beaches.
Evangelistria Monastery and the First Greek Flag
Type: Monastery, museum, history, viewpoint
Time needed: Half a morning including the bus
Access: The 2 euro bus from the port, roughly hourly; or drive; or walk up in about an hour, steeply
Cost: Free to enter; small charge for the museum
Best time: Morning, before the minibus fills
Five kilometres up in the pines above the town is the reason Skiathos matters to Greeks in a way it does not to the charter crowd.
Evangelistria was founded in 1794 by Kollyvades monks who had walked out of Mount Athos over a dispute about when memorial services should be held. In September 1807, in this courtyard, a group of klephts and sea captains, Theodoros Kolokotronis and Andreas Miaoulis among them, swore an oath of freedom on a newly woven flag of a white cross on a sky blue field. That was the first Greek flag, and the loom it was woven on is still here, in the museum in the old olive press, alongside manuscripts, vestments and carved crosses.
Because women were present at the weaving, Evangelistria broke with Athos practice and admits them, which is why, unlike the mountain it came from, everyone can go in.
A handful of monks still run the place and still make wine, olive oil and honey. The shop is worth ten minutes and the produce travels better than anything in the souvenir shops in town.
Good to know: cover shoulders and knees; wraps are lent at the door. The island only runs a minibus up the mountain road, so it fills at peak times. The signposted trail from the monastery out to Kastro is the best walk on the island, roughly four hours with the loop back.
Best for: Anyone who wants an hour of quiet and some actual history; hikers starting the Kastro trail.
Parissis Winery, Higher Up the Same Hill
Skiathos has exactly one vineyard, and it is further up the same road as the monastery. Parissis opened in 2019, which on an island this size makes it practically brand new, and the climate here suits whites and roses rather than reds. A booked tour walks you through the grapes and the bottling, then sits you on a terrace with a view over the whole town and the bay for the tasting, usually with a cheese and charcuterie board.
Reserve in advance through the winery directly, because they do not take walk-ins reliably. The road up is steep and in poor repair in places, which is the honest argument for booking a tour with transport rather than driving yourself and then tasting. If you cannot get up there, several restaurants on the island pour Parissis wines by the glass.
Lalaria Beach & the Blue Caves
Type: Boat-access beach, sea caves, swimming, photography
Time needed: 2–3 hours at Lalaria; combine with caves and Kastro for a full half-day
Access: By boat only — no road or path reaches Lalaria; excursion boats depart Skiathos new port
Cost: Day cruise tickets from €25–60 per person; private speedboat charters from €350/half day
Best time: Morning light for the clearest water colours; avoid the midday heat and boat crowds
Lalaria sits at the far north of Skiathos, tucked beneath white limestone cliffs that drop sheer to the water. The beach is entirely pebble — smooth, pale grey-white stone polished into almost perfect rounds by the sea — and the water directly off the shore is a deep aquamarine that deepens to navy toward the open Aegean. There is no shade, no facility, no staff. Just the cliffs, the pebbles, the water, and the boat you arrived on.
The adjacent sea caves are accessible through arches carved by wave erosion into the limestone. The most impressive is the largest natural arch, through which the sky is visible above and the sea floor below — in the right light, the water inside glows blue. Boats enter the caves and pause long enough for photographs and, in the calmer conditions of June and September, for confident swimmers to slip in.
Book the Cruise to Lalaria, Kastro, and Tsougris on GetYourGuide
Book the Private Lalaria Beach and Caves Speedboat Tour on GetYourGuide
Both a group day cruise and a private speedboat option are available on GetYourGuide. The day cruise is the most economical and includes stops at Kastro and Tsougris Island; the private speedboat covers Lalaria and the caves more thoroughly and at your own pace.
Good to know: Lalaria is inaccessible in strong north winds (meltemi) — conditions can cancel departures in July–August. Book with free cancellation and check the forecast. The pebbles at Lalaria are slippery at the water's edge; water shoes help considerably. Bring everything you need for the day: water, food, sun protection.
Best for: Anyone visiting Skiathos; Lalaria is the single non-negotiable experience on the island.
Kastro: The Ghost Village on the Cliffs
Type: History, archaeology, hiking, panoramic views
Time needed: 1.5–2 hours including the walk up and the ruins; combine with Lalaria for a half-day boat excursion
Access: By boat to the small beach below, then 15-minute walk up through pine forest; or 8km by rough road and trail from Skiathos Town
Cost: Free; accessible via boat excursions departing Skiathos port
Best time: Morning before the boat-day crowds arrive; the ruins are fully exposed to sun
Kastro was built on a high rocky promontory on the north coast sometime in the 13th or 14th century, when the threat of pirate raids made a defensible hilltop position essential. The village was designed with a single landward entrance — a fortified gate with a drawbridge — and the 50-metre cliffs as its other three walls. At its peak, around 300 houses and 22 churches occupied this windswept peninsula above the sea.
The inhabitants abandoned it entirely in 1829, when Greek independence reduced the piracy threat and the more convenient coastal site of modern Skiathos Town became the island's new centre.
Today Kastro is a ruin: stone walls standing to varying heights, the remains of two restored churches (Christos and the Chapel of the Birth of Christ), and a Byzantine cannon still pointed seaward at an enemy that no longer comes. The promontory views are extraordinary — north over open Aegean, south over the pine-covered hills of the island, and on clear days east to Skopelos.
The walk up from the boat landing takes about 15 minutes through shaded pine forest, which makes it manageable even in midsummer. Most visitors arrive as part of a Lalaria day cruise that includes a Kastro stop.
Good to know: Wear grip-soled shoes for the rocky path up to the ruins. The site is unlit and has no facilities. The restored churches are sometimes locked — visit times can depend on local volunteer custodians. The best view of the promontory itself is from the water, on approach by boat.
Best for: History and archaeology enthusiasts, photographers, hikers combining the north coast trail with a boat return.
Walking to Kastro, and the Rest of the Trail Network
Skiathos has a signposted walking network that almost nobody arriving on a charter flight knows exists. It was built by one man, Ortwin Widmann, who moved here decades ago and cleared and mapped a set of old mule paths into marked circular routes running from under two kilometres to about eleven. They are waymarked in red and white, and a free map circulates in the shops in town.
The two worth your time both involve Kastro. One climbs from Evangelistria Monastery out to the promontory and loops back, which takes roughly four hours and is the best walk on the island. The other runs from Koukounaries through the pine forest and dunes over to Mandraki and Elias on the north coast, which is how you reach those beaches without a vehicle.
Go early, carry more water than you think, and remember the forest shade ends where the ruins begin. Confirm the current route numbering against the latest Skiathos Trails map, which is revised periodically.
Koukounaries & the South Coast Beaches
Type: Beaches, swimming, sunbathing, water sports
Time needed: Half day per main beach; a south coast circuit by road or water bus covers 5–6 beaches
Access: Koukounaries by bus from Skiathos Town (30 min, bus route serves all south coast beaches); water taxi and road access
Cost: Free; beach loungers €10–15/day; water sports from €20
Best time: Early morning for the best light and smallest crowds; June and September for the best ratio of warmth to space
Koukounaries is the most famous beach on Skiathos and one of the most photographed in Greece. A 1.2km arc of white-gold sand backed by a mature Mediterranean pinewood, with a shallow lagoon behind the beach as well as the sea in front, it is objectively beautiful. It is also, in July and August, one of the busiest beaches in Greece — a corridor of sun-loungers, beach bars, and water sports operators from end to end. Arrive before 10am to see what it looks like before the crowd arrives.
The south coast road running from Skiathos Town to Koukounaries passes approximately 20 named beaches, and the island's water bus services several of them on regular circuits. Banana Beach (a double bay of soft sand, popular with water sports enthusiasts), Vromolimnos (wider and slightly less crowded than Koukounaries), and Agia Paraskevi (quieter, good for families) all merit stops. Platanias, Megali Ammos, and Achladies are close enough to town to walk or cycle.
The north coast beaches — Kehria, Mandraki, Megali Xersia — are accessible only by boat or on foot via rough trails and are a complete contrast to the south: isolated, unpacked, in settings of pine forest and rocky headland.
Good to know: The bus along the south coast road runs every 20–30 minutes in peak season from Skiathos Town — it is the cheapest and most practical way to beach-hop. The lagoon behind Koukounaries (Strofilia wetland) is a protected biotope and nesting area for birds; a walking path circles it. Water taxis operate along the south coast with flexible pick-up and drop-off.
Best for: Beach lovers of all types; families; water sports enthusiasts; anyone who wants the full Aegean beach experience.
Xanemos, and Standing Under the Runway
The runway runs almost the full width of the island, and its threshold sits directly behind the beach at the eastern end. This is one of a handful of airports in the world where you can stand underneath an arriving aircraft, and in summer a small crowd gathers on the road at the end of the strip to do exactly that. Departures are the loud ones: the jet blast off the end of the runway will knock you sideways if you stand where the signs tell you not to.
Xanemos Beach, behind the runway, is the place to watch take-offs and has its own bus from the port. Check the airport arrivals board before you go, because outside the mid-afternoon charter bank there can be an hour with nothing moving. Bring ear protection if you are taking children.
Sailing & Day Cruises
Type: Boat trips, sailing, swimming, snorkelling, island views
Time needed: 6–8 hours for a full-day sailing circuit
Access: Depart from Skiathos new port
Cost: From €50–90 per person on shared sailing boats; private charters from €700/day
Best time: June–September; July–August has reliable winds for sailing but busy departure queues
The boat excursion scene in Skiathos is one of the most varied and active in northern Greece. Traditional caique cruises, modern sailing yachts, and private speedboats all depart from the new port daily in season, covering combinations of Lalaria, the Blue Caves, Kastro, the south coast beaches, Tsougris Island, and — on longer itineraries — Skopelos.
A full-day sailing trip with swim stops and lunch is the best single day you can spend on the island. Small-group sailing boats (typically 8–12 passengers) offer a more intimate experience than the large cruise boats, with flexible itineraries that adjust to wind and conditions. Several operators on GYG provide exactly this format, with excellent reviews for food, crew attitude, and access to boat-only beaches.
Book the Day Sailing Trip with Swim Stops and Lunch on GetYourGuide
Good to know: Check what is included — some cruises include lunch and drinks; others do not. Small-group sailing boats provide a noticeably different experience from the 40-person caique cruises. Free cancellation is essential given the weather dependency of sailing itineraries.
Best for: Anyone who wants a relaxed, social day on the water with swimming, good food, and scenery.
Tsougria, the Cheap Version of the Boat Day
The small island you can see from Skiathos Town is Tsougria, and it is twenty minutes away by water taxi from the old port. Two beaches, a taverna, water clear enough to see the bottom well out from shore, and a fraction of the crowd that ends up on the big circuits.
This is the boat day for people who do not want a boat day. You go when you like, you come back when you like, and it costs a fraction of a full-day cruise. Most of the larger tours stop here anyway, which tells you something about the water.
Sea Kayaking the South Coast
Type: Water sports, kayaking, swimming, snorkelling, coastal exploration
Time needed: 3–4 hours (half-day tour)
Access: Meet at Sklithri Beach (bus stop 11); short transfer from Skiathos Town
Cost: See GYG listing for current pricing
Best time: Morning departure; calmer sea conditions in June and September
Skiathos has a well-developed sea kayaking operation along its south coast, and it is one of the most accessible and well-reviewed active experiences on the island. The route follows the coastline past rocky headlands, enters a sea cave, and reaches beaches accessible only from the water — the same features that make the boat trips compelling, but at your own pace, in silence, with a paddle in your hands.
The guided half-day tour departs from Sklithri Beach, passes through a limestone sea cave, and reaches Diamanté Beach — a remote cove of clear water with no road access. Snorkelling gear and fruit are provided at swim stops. The guide is experienced and the group is small, making it one of the more personal water activities available on the island.
Book the SUP and Sea Kayak Tour with Swim Stop on GetYourGuide
Good to know: No kayaking experience is required. The tour is weather-dependent — confirm 24 hours before. Wear a rash vest or UV-protective swimwear; the sun exposure while paddling is significant. Water shoes are useful for the rocky entry and exit points.
Best for: Active travellers, couples, small groups; anyone who wants to explore the coastline at their own pace without a large crowd.
Day Trip to Skopelos & Alonissos
Type: Island hopping, boat excursion, village exploration, cinema tourism
Time needed: Full day (departure ~9am, return ~6:30pm)
Access: Boat departs Skiathos port; various operators run daily in season
Cost: Typically €35–60 per person including boat; lunch at own expense
Best time: June–September; daily departures in high season
Skopelos is the most beautiful and underrated island in the northern Sporades, and from Skiathos it is 1.5 hours away by excursion boat. The island's main town is extraordinary: a compact hillside of white-painted houses, 123 churches, blue-domed chapels perched on clifftops, and a harbour of fishing boats that has been used continuously since ancient times. The chapel of Agios Ioannis, reached by 200 rock-cut steps on a clifftop above Kastani Beach, is the church where key scenes of the film Mamma Mia were shot — and it remains as dramatic and beautiful as it appeared on screen.
Most excursion boats from Skiathos continue to Alonissos after Skopelos, adding a second island to the day. Alonissos has a less photogenic port but a spectacular hilltop Old Town, and the surrounding waters form part of the National Marine Park of the Northern Sporades — one of the most important protected marine habitats in the Mediterranean, home to the rare Mediterranean monk seal.
Book the Skopelos and Alonissos Boat Trip from Skiathos on GetYourGuide
Good to know: Pack a compact daypack with everything you need — the excursion boat does not store luggage. Kastani Beach is typically included as a swim stop on boats doing the Mamma Mia circuit; confirm the itinerary before booking. The chapel of Agios Ioannis involves 200 steps — manageable in trainers, harder in sandals.
Best for: Film fans, island hoppers, anyone with more than 3 days on Skiathos looking to extend the experience into the wider Sporades.
When the Meltemi Blows, or You Came in October
Two things reliably go wrong on a Skiathos holiday, and neither is covered by the standard list.
The first is wind. When the meltemi gets up in July and August, the north coast closes: Lalaria departures are cancelled, the caves are unenterable, and the boat you booked does not sail. This is normal and it is why every operator worth using sells free cancellation. The answer is to flip the day inland rather than write it off. Evangelistria and the Kastro trail are sheltered by pine forest. The town is fine in any wind. The south coast beaches face away from it, so Vromolimnos, Agia Paraskevi and Kanapitsa stay swimmable when the north is unreachable. Book Lalaria for early in your stay, not the last day, so a cancellation has somewhere to go.
The second is season. Skiathos in September is still a full summer island. October is the handover: the sea holds its heat, the light is better than at any point in August, the town stays open, but boat departures thin out to a few a week and some of the beach tavernas have already shut. By November most of the island is closed. If you are coming in October, do the boat trips in your first three days and treat the town, the monastery and the trails as the reliable core of the week, because those do not stop.
Practical Information
Getting to Skiathos: Skiathos Airport (JSI) receives direct charter and scheduled flights from the UK and Europe in summer, and domestic connections from Athens year-round via Sky Express and Olympic Air.
Alternatively, ferry from Volos or Agios Konstantinos on the mainland (approximately 2.5 hours by fast catamaran). Check current schedules on Ferryscanner.
- Book an airport transfer in advance with Welcome Pickups — fixed price, English-speaking driver, no haggling at the rank.
- For cheap flights to Skiathos, compare deals on Kiwi.com — searches across all carriers.
The Bus, and Why You Probably Do Not Need a Car
One line runs the south coast from the port, which is stop 0, to Koukounaries at stop 26, every 15 to 30 minutes from early morning until after midnight in high season. Nearly every beach on that stretch has its own numbered stop, and you tell the driver the number rather than the name, which is the single most useful thing to know before you land.
Fares run in two bands: roughly 2 euros for anything up to Agia Paraskevi at stop 16, and roughly 3 euros beyond that, including the airport. Confirm current fares with the driver or at the port kiosk, as they are set season by season.
Three shorter lines matter too: the port to Evangelistria for the monastery, the port to Xanemos for the beach behind the runway, and Troulos to Aselinos, which is the only bus that crosses to the north coast.
Where the bus stops being enough is the north coast, Kastro by land, and the interior, all of which need a scooter, an ATV or a car. That is genuinely it. If you are staying anywhere on the south coast and are happy there, you can do a full week without renting anything.
Water taxis from the old port are the underrated alternative. They run along the south coast and out to Tsougria, they leave when they are full, and they cost a fraction of a boat tour.
When to go: June and September offer the best balance: warm sea, manageable crowds, accessible accommodation, and the full range of boat excursions operating. July–August are peak season — the island is busy, accommodation prices are at their highest, and Koukounaries fills by mid-morning. The airport handles peak summer traffic that far exceeds the island's permanent population of around 6,000.
Budget: Mid-range travellers should budget €90–150 per person per day including accommodation, meals, and a boat excursion. Eating well in Skiathos Town costs €20–35 per person at dinner. A private speedboat charter for a half-day runs €350–500 depending on size and itinerary.
Staying connected: Non-EU visitors face high roaming charges on Greek networks. Activate a Yesim eSIM before you fly — instant setup, no physical SIM, works the moment your plane lands in Greece.
Skiathos or Skopelos?
People planning the Sporades usually end up choosing between these two, and the honest answer depends on one question: do you want the island to be easy, or do you want it to be quiet?
Skiathos has the airport, which means you fly in directly rather than routing through Athens and a ferry. It has the better beaches, a bus that makes them free to reach, a real town with somewhere to eat every night of the week, and the nightlife. It is also the busiest of the three in August.
Skopelos is greener, slower and has the Mamma Mia sites, including the chapel everyone comes looking for. It has no airport, so you fly into Skiathos anyway and ferry across in 45 minutes.
Which is why most people do not actually choose. They base on Skiathos, day-trip to Skopelos, and get both. If you only have four or five days, that is the answer.
For the Skopelos half of that plan, our guide to Skopelos covers the ferry from Skiathos, the beaches and the Mamma Mia locations.
