Dodecanese Islands Cruises

The Dodecanese are a chain of Greek islands strung along the southeastern Aegean, hard against the Turkish coast — 15 sizeable islands and some 150 islets, 26 of them inhabited, covering 2,714 sq km (1,048 sq mi). Rhodes and Kos are the big, well-served names; Patmos, Symi, Kalymnos, Nisyros, Leros, Tilos and Karpathos are the quieter ones that reward a cruise or a charter. They were the last part of Greece to join the modern state, formally incorporated on 7 March 1948 after 36 years of Italian rule.

Patmos sits in the northern Dodecanese, roughly halfway between Kos and Samos, and about 6 km (4 mi) off the Turkish coastline at its closest point. It is small — 34 sq km (13 sq mi), rising to Profitis Ilias at 269 m (883 ft) — with the port of Skala below the hilltop village of Chorá. The Monastery of Saint John the Theologian and the Cave of the Apocalypse were inscribed as a UNESCO World Heritage Site in 1999, which is why so many small ships call here.

The classic Dodecanese week runs north to south with the prevailing meltemi behind you: Kos to Kalymnos, then Leros, Lipsi and Patmos, or the southern loop from Rhodes to Symi, Tilos and Nisyros. Legs are short — mostly 15–25 nautical miles (28–46 km) — and the Turkish coast to the east breaks the swell that batters the open Cyclades. Plan the long hops for the morning: the meltemi freshens after midday and can push Force 6–7 through the island channels from July to August.

The chain runs roughly north–south for about 200 nautical miles (370 km / 230 mi) down the eastern edge of the Aegean, from Patmos in the north to Karpathos and Kasos in the south, closer to Asia Minor than to mainland Greece. Rhodes, the southern anchor, lies 363 km (226 mi) east-southeast of the Greek mainland but just 18 km (11 mi) from Turkey at the nearest point. On a map, they form the frontier of Greece — which is exactly why their history is so layered.

Patmos has no airport, so every arrival is by sea — which is part of its appeal. Dodekanisos Seaways catamarans link it with Kos in 1½ to 2 hours and with Rhodes and Leros daily in season, while Blue Star runs the long overnight sailing from Piraeus. Small cruise ships anchor off Skala and tender in, then climb the 4 km (2.5 mi) road to Chorá.

Walk the walled medieval town of Rhodes, float over the sunken Roman remains off Kos, and descend into the Stefanos crater on Nisyros, an elliptical hydrothermal vent roughly 260 by 330 m (850 by 1,080 ft) and 27 m (89 ft) deep where the ground steams under your boots. Kalymnos has become one of Europe's great sport-climbing islands, with more than 4,000 bolted routes across 61 crags, according to the 2025 guidebook. Symi's harbor of ochre neoclassical mansions and Patmos's monastery are the two sights most cruise itineraries center on.

It is Greek for 'twelve islands' — dódeka, twelve, and nìsos, island — and it is pronounced doh-dek-uh-NEEZ. The name is misleading: there are far more than twelve, and it was originally attached to a group of Cycladic islands before being transferred here under Ottoman rule, when twelve of these islands held special tax privileges. So the number records an administrative arrangement, not a headcount of land.

Rhodes, comfortably — 1,401 sq km (541 sq mi), about 80 km (50 mi) long and 38 km (24 mi) across at its widest, with a population of roughly 125,000. Karpathos is a distant second at 325 sq km (125 sq mi), then Kos at 290 sq km (112 sq mi). Everything else in the group is under 110 sq km (42 sq mi), which is why island-hopping here feels so unhurried.

The Cyclades ring the sacred island of Delos in the central Aegean — whitewashed cubes, bare rock, and the full force of the meltemi. The Dodecanese lie further east along the Turkish coast and wear a different history: Byzantine, then Knights Hospitaller, then Ottoman, then Italian until 1948, which left neoclassical harbors and Rationalist architecture you will not find on Mykonos. For sailors, the practical difference is shelter — the Cyclades take the worst of the summer wind, while the Dodecanese offer shorter, more protected hops.

Kos lies within about 5 km (3 mi) of the Bodrum peninsula — close enough that the lights of Turkey are visible from its eastern beaches — and there are daily summer ferries between the two. Rhodes is also strikingly close, 18 km (11 mi) at the nearest headland and roughly 25 nautical miles (46 km / 29 mi) from Marmaris by fast ferry, a crossing of about an hour. Kastellorizo, the easternmost point of Greece, lies barely 2 km (1.2 mi) off the Turkish town of Kaş.

Rhodes has by far the largest forests in the group — pine and cypress across the Profitis Ilias range and the flanks of Mount Attavyros, which rises to 1,216 m (3,990 ft). Among the smaller islands, Leros and Tilos are the ones usually called green, though that means olive groves, pine pockets, and spring wildflowers rather than continuous woodland. Kos is agriculturally lush without being forested; the rest of the chain is classic Aegean scrub and terraced stone.

Eight of them. Rhodes (Diagoras) and Kos (Hippocrates) are the usual gateways for a cruise or charter; Karpathos, Kalymnos, Astypalaia, Kasos, Leros, and Kastellorizo have smaller domestic airfields served from Athens and Rhodes. Patmos, Symi, Nisyros, Tilos, Chalki and Lipsi have no airport at all — you reach them by ferry, which is why small ships have the run of them.

Yes, and they suit the geography better than big ships do. Vessels of 30 to 200 passengers can tie up in Symi's Gialos harbor or anchor off Patmos and Nisyros, where cruise terminals do not exist, and the water is deep close in; many itineraries string the Dodecanese together with the eastern Cyclades over seven to ten nights. The season runs roughly April to October, with the calmest cruising in May–June and September–October as of 2026.

Two systems overlap. Dodekanisos Seaways high-speed catamarans run the chain daily in season for the short hops — Rhodes to Symi in 45 minutes to 1½ hours, Kos to Patmos in about two hours — while Blue Star's conventional ships handle the long overnight run from Piraeus, 15 to 25 hours to Rhodes. The catch is the meltemi: from July to August, strong northerlies cancel fast-craft sailings at short notice, so leave a buffer day before a flight home.
