Two weeks to sail the whole Dodecanese from Kos: south past the Nisyros volcano, Tilos and Halki to Rhodes and Symi, then back north through Kalymnos, Leros, Patmos and Lipsi. It is the only way to see both faces of the archipelago without a one-way charter: the knights' city and neoclassical waterfronts in the south, monasteries and quiet islets in the north. Around 265 miles, with one key leg to sail upwind. Details below.

Highlights

Nisyros, the Dodecanese volcano: from Pali, head up to the Stefanos crater, then explore Mandraki and its lanes below the Spiliani monastery.
Tilos and Halki, two tiny, almost car-free islands that set the slow pace of the southern archipelago.
Rhodes, the medieval city of the knights, a UNESCO World Heritage site, explored on foot from Mandraki. The day ashore is well spent.

Symi, the neoclassical amphitheatre of Gialos, then the enclosed bay of Panormitis and its monastery, one of the best-sheltered moorings of the loop.

Leros, the Lakki roadstead and its 1930s Italian rationalist architecture, one of the safest natural harbours in the eastern Aegean.
Patmos, the Monastery of Saint John and the Cave of the Apocalypse above Chora, the second UNESCO site on the route.
Marathi, Arki and Lipsi, the quiet Dodecanese: fishermen's tavernas, turquoise water, one anchorage per islet. Full details in our 7-day northern Dodecanese itinerary.
Vathy fjord on Kalymnos, a narrow rocky inlet opening onto a valley of mandarin groves.
Technical points and watch-outs
- Turkish waters: between Rhodes, Symi and Kos the route runs a few miles off the Turkish coast. Do not enter Turkish territorial waters without Schengen exit and entry formalities, and check your charter contract, which usually forbids it.
- D8, Panormitis to Kos: the key leg, 40 miles upwind in the north-westerly Meltemi. Leave at dawn, before the wind builds, or break it at Nisyros (Pali) if the breeze is strong. This is why two buffer days come before it (the day in Rhodes, the short hop on Symi).
- D4, Halki to Rhodes: 38 miles up the west coast of Rhodes and round the northern tip, where the sea gets confused. Book Rhodes marina in high season, Mandraki is packed.
- Symi, Gialos: a very busy harbour in summer, with afternoon gusts racing down the hills. Arrive before 2 pm, set the anchor well, double your lines.
- Kalymnos, Vathy: a narrow fjord, moor alongside or stern-to, no swinging room. Well sheltered from the Meltemi.
- D14: midday swim at the Pserimos anchorage, then back to Kos within the base's check-in window.
Book and prepare
- Compare the yachts and catamarans available from Kos.
- Charter insurance recommended, all the more over two weeks.
- Flights: to Kos (KGS), direct in season; Rhodes (RHO) as an alternative for a one-way version.
- Activities: Nisyros crater, Rhodes old town, Patmos monastery, climbing on Kalymnos.

A word from the crew
Logbook. Two weeks in the Dodecanese means no longer choosing between Rhodes and Patmos. The southern week is sailed downwind, the northern week in the shelter of the big islands: this archipelago suits a loop better than the Cyclades.
The mistake to avoid. Sailing the loop the other way round. Heading north first leaves the upwind leg from Symi for the last two days, with no margin if the Meltemi picks up.
Our favourite, and what we skip. Favourite: Panormitis bay at sunset, and Arki. Skip: Kos town in the middle of August; one evening at the start is enough.
Our verdict. Beauty 5/5. Anchorages 4/5. Ease 3/5. Crowds 4/5. Verdict: the most varied loop in eastern Greece, as long as you respect the direction of travel.
