Dodecanese Islands: The Complete Visitor and Island-Hopping Guide

The Dodecanese are the easternmost islands of Greece — the chain that runs along the Turkish coast from Samos in the north to Rhodes in the south, with Kastellorizo sitting alone, 570 km from Athens and 2 km from Turkey. To fly from Athens to Rhodes takes 45 minutes; to reach Kastellorizo takes 45 minutes plus a stop. The geography shapes everything: the Turkish coast is visible from almost every Dodecanese island, the historical relationship with the East runs deeper here than anywhere else in Greece, and the combination of Byzantine, Crusader, Ottoman, and Italian occupation has produced towns and cultures of extraordinary layered complexity.

The group is not a uniform destination. It is fifteen inhabited islands ranging from Rhodes (population 115,000, international airport, 400-hotel resort strip) to Agathonissi (population 160, no cars, a small harbour and a handful of houses). Planning a Dodecanese trip means choosing your position on that spectrum and building the right combination.

The Main Dodecanese Islands

Rhodes (Ρόδος): History, Beaches, and the Medieval City

Rhodes is the capital, hub, and largest island of the Dodecanese — 1,401 km², a population of roughly 115,000, and the most visited island in the eastern Aegean. It has an international airport with direct flights from across Europe, the most developed tourist infrastructure in the group, and the most extraordinary medieval city in the Mediterranean.

The Old Town of Rhodes is the reason to visit. The walled medieval city — built by the Knights of St John after 1309 and expanded across two centuries — is inhabited, functioning, and intact in a way that is almost uniquely found in Europe. The walls are complete. The moat is dry but walkable. The Street of the Knights (Ippoton Street) is lined with the original inns of the seven national "tongues" of the Order, perfectly preserved in their 15th-century form. The Palace of the Grand Master was destroyed in an ammunition explosion in 1856 and rebuilt by the Italians in the 1930s as a summer residence for Mussolini (who never came) — the result is a historically ambiguous but visually striking museum.

Inside the Old Town: the old Jewish quarter (largely deported to Auschwitz in 1944, commemorated in the museum near Plateia Martyron Evreon), the Ottoman quarter with its mosques and hammam, and Byzantine churches incorporated into later structures. Outside: Lindos — whitewashed village, a Crusader castle, and a Doric temple of Athena on the acropolis above a fishing harbour. See the Lindos guide for the full visit guide.

Kos (Κώς): Hippocrates, Archaeology, and the Northern Hub

Kos is the second largest and second most visited Dodecanese island — 290 km², flat terrain ideal for cycling, and some of the best sandy beaches in the group. It is also the birthplace of Hippocrates, the father of medicine, and the historical weight of this sits strangely alongside the beach bars and resort hotels of the northern coast.

Kos Town is a compelling mix of ancient ruins, the medieval Castle of the Knights, and Italian Rationalist architecture. The Asklepieion (4 km from town) is the ancient sanctuary where Hippocrates taught — three terraced levels of ruins on a pine-forested hillside with views to Turkey. The Plane Tree of Hippocrates in the main square is reputedly the oldest tree in Europe (probably not, but it is at least 500 years old, and the story is good). Mastichari is the ferry port for Kalymnos day trips — 30 minutes by boat.

See the Kos travel guide for the complete island guide.

Symi (Σύμη): The Most Beautiful Harbour in the Dodecanese

Symi is the Dodecanese's aesthetic jewel — a small island 24 km north of Rhodes whose harbour town is one of the most architecturally cohesive and visually striking in all of Greece. The neoclassical mansions of Gialos (the lower harbour) rise in tiers of ochre, terracotta, and gold above the horseshoe bay, built by wealthy sponge merchants and sea captains in the 18th and 19th centuries.

Most visitors come as day trips from Rhodes (50–90 minutes crossing). The correct visit is an overnight or multi-night stay — the afternoon boats carry the day-trippers away and leave behind the island's genuine pace, which is slow, sun-drenched, and entirely without urgency. Key sights: the Clock Tower above the upper town (Chorio), the Monastery of Archangel Michael Panormitis (one of the most important pilgrimage sites in the Dodecanese), and beaches that must be reached by boat — with some of the clearest water in the Aegean.

Patmos (Πάτμος): The Sacred Island

Patmos is where St John the Apostle, exiled by the Emperor Domitian, is said to have received the visions described in the Book of Revelation. The Cave of the Apocalypse is on a hillside between the port of Skala and the fortified hilltop monastery. The Monastery of St John the Theologian (founded 1088) dominates the island's skyline — a Byzantine fortress whose library holds some of the most important Byzantine manuscripts in existence.

Patmos is a small island (34 km²) with a mystical atmosphere that is genuinely different from the rest of the Dodecanese. It attracts pilgrims, intellectually curious travellers, and a small international community who have chosen the island for its specific quality of peace. The main town of Chora has some of the finest traditional Aegean architecture in the group — whitewashed houses, stone lanes, and views across to the surrounding islands. Psili Ammos beach in the south (reached by boat) is considered one of the finest in the Dodecanese.

Kalymnos (Κάλυμνος): The Sponge Diving Island

Kalymnos is defined culturally by sponge diving — a tradition embedded in its museum, its mythology, and its architecture. Today it is also one of the world's top rock-climbing destinations, with the limestone cliffs above the main town drawing climbers from across Europe particularly in spring and autumn. The port town of Pothia is a genuine working town, not a resort, and has some of the most interesting island capital architecture in the Dodecanese.

From Mastichari on Kos, the ferry to Kalymnos takes 30 minutes. From Kalymnos, the day trip to tiny Telendos (€3 return by local caique, 5 minutes) is one of the best short trips in the Dodecanese — an almost uninhabited island of total tranquillity and excellent swimming.

Karpathos (Κάρπαθος): The Traditional One

Karpathos is one of the least-changed traditional islands in the entire Aegean. The northern village of Olympos preserves customs, costumes, and a dialect that disappeared from the rest of Greece a century ago. Women in Olympos wear traditional dress daily — not for tourists but because this is what they wear. The island has excellent beaches (Apella is frequently listed among the finest in the Dodecanese), a dramatic mountainous interior, and an airport with direct Athens connections. For visitors wanting the Dodecanese's physical beauty without the resort infrastructure, Karpathos is the right answer.

Nisyros (Νίσυρος): The Volcano

Nisyros is a volcanic island with an active caldera. The Stefanos crater is the most accessible active volcanic crater in Greece — a short walk from the rim to the crater floor, where sulphur vents hiss and the ground is warm underfoot. The entire island is the surviving rim of a volcanic cone; the almost circular island shape visible on any map is the volcano's outline.

The main village of Mandraki has the finest intact traditional architecture in the smaller Dodecanese — stone houses, a Byzantine church, a Crusader kastro above the village, and the extraordinary Panagia Spiliani monastery built into a cave in the castle rock. Nisyros has a population of around 950 and almost no mass tourism. Most visitors come on day trips from Kos (1.5–2 hours). An overnight stay, after the day-trippers leave, is one of the best choices in the Dodecanese.

Leros (Λέρος): Italian Architecture and Atmosphere

Leros is one of the most interesting smaller Dodecanese islands for architecture. The Italian Rationalist buildings here are more concentrated and better preserved than almost anywhere else in the group. The Lakki port — built by Italy as a naval base in the 1930s — is an extraordinary example of Fascist-era planned urbanism: wide boulevards, a circular market hall, a cinema, and a hotel in impeccable Rationalist style, all set in one of the finest natural harbours in the Aegean. The island also has excellent beaches, a Byzantine castle above the main town of Platanos, and a significantly less touristy atmosphere than Rhodes or Kos.

Kastellorizo (Καστελλόριζο): The Furthest Point

Kastellorizo (also called Megisti) is the most remote inhabited island in Greece — 570 km from Athens, 2 km from Turkey, population around 500. It was the setting for the Oscar-winning Italian film Mediterraneo and has the most colourful harbour front in the Dodecanese — painted houses in red, blue, and yellow reflected in water of extraordinary clarity.

There are no beaches; swimming is from rocks or by boat. The Blue Cave (Galazia Spilaio) — a sea cave with bioluminescent reflections at midday — is the primary excursion. Reaching Kastellorizo requires either a domestic flight from Rhodes or Athens, or a ferry from Rhodes (3–3.5 hours). The effort is the point.

Island-Hopping the Dodecanese: How It Works

The Two Hub Strategy

The Dodecanese ferry network is organised around two hubs. Rhodes serves the southern islands: Symi, Tilos, Nisyros, Kos, and longer routes to Karpathos and Kastellorizo. Kos serves the northern chain: Kalymnos, Leros, Patmos, Lipsi, and smaller islands further north.

The most practical approach: choose one hub as your entry point and work outward. Trying to combine both in a single trip requires backtracking and significantly complicates logistics.

Main Ferry Operators

Blue Star Ferries run the primary Piraeus-to-Dodecanese route several times per week, calling at multiple islands. The overnight Piraeus–Rhodes ferry (approximately 16–18 hours) stops at Patmos, Leros, Kalymnos, and Kos — one of the classic Greek ferry journeys.

Dodekanisos Seaways is the inter-island high-speed catamaran covering most of the chain. The essential operator for island-hopping within the group — check their seasonal schedule, as services reduce significantly outside May–October.

Getting to the Dodecanese

By air: Rhodes (RHO) and Kos (KGS) have international airports with direct summer charter flights from the UK, Germany, and Scandinavia, plus year-round Athens connections. Karpathos and Leros have domestic airports with Athens links.

By ferry from Piraeus: Blue Star Ferries run the Piraeus-Dodecanese route several times per week. The overnight ferry to Rhodes takes approximately 16–18 hours; to Kos approximately 12 hours. Book via Ferryhopper or direct with Blue Star.

By ferry from Turkey: Short crossings operate between Bodrum and Kos, and between Marmaris and Rhodes — making the Dodecanese a natural part of a combined Greece-Turkey itinerary.
