Skiathos is not a secret. It has a small airport that receives direct charter flights from Britain and northern Europe all summer, 60-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.
The north coast is wild and largely inaccessible by land — its beaches, caves, and the ghost village of Kastro visible only from the sea. The sailing scene is diverse and well-run: everything from 40-person cruise boats to two-person kayaks.
Skopelos, the greener and quieter Mamma Mia island, is 1.5 hours away by boat. And the evening atmosphere in the old port, with the Bourtzi fortified islet in the foreground and the boats lit in the harbour, is genuinely one of the most pleasant in Greece.
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.

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.
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.

Book the Private Lalaria Beach and Caves Speedboat Tour on GetYourGuide
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.
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.
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.
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 Guided Sea Kayaking 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.
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.
Getting around: The island bus runs along the south coast road every 20–30 minutes in season, stopping at all major beaches from Skiathos Town to Koukounaries — a practical and cheap way to beach-hop. Taxis are available from the old port taxi rank. Scooters and small cars can be hired from agencies near the port; the main road is reasonably well-maintained.
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.
