Dalyan sits where the Köyceğiz lake drains to the Mediterranean through a maze of reed-lined channels. Wooden river boats thread these channels past the rock-cut tombs of ancient Kaunos, pause at sulphur-rich mud baths, and carry visitors out to Iztuzu, one of the most important loggerhead turtle nesting beaches in the eastern Mediterranean.

01Why Dalyan & Iztuzu
Few day trips on the Turkish coast pack so much variety into a single boat. In one circuit you drift past 2,400-year-old Lycian-style tombs carved into a cliff face, soak in warm mineral mud, and end up on a protected sandbar beach that has been kept wild precisely because it is a turtle nursery. It is part nature reserve, part open-air archaeology, and part beach day — without a single long coach transfer in between.
The Kaunos tombs are best seen from the water, glowing amber in the late afternoon light as the boats turn back toward town.
02The river route
- Dalyan quay · boats set off from the town waterfront and head into the reed channels of the delta
- Kaunos rock tombs · the carved temple-front tombs of the ancient city loom over the river bend
- Mud baths & hot springs · a stop at the sulphur mud pools and thermal pool near Köyceğiz
- Iztuzu beach · the long sandbar between river and sea, with several hours of beach time
- Return cruise · back through the channels to Dalyan, often timed for the softer evening light

05Best time to go
May–June and September–October are the sweet spots, with warm water and thinner crowds. July–August is hottest and busiest, so early starts help. Most boats run April to October; winter service is limited and weather-dependent. Note that Iztuzu is a protected nesting beach: it closes at night during the loggerhead nesting season (roughly May to October), and sun loungers are kept back from the marked nesting zone.
06What you will see
On the river and at Kaunos:
- Kaunos rock tombs — temple-front tombs cut into the cliff above the river
- The ruins of ancient Kaunos — theatre, acropolis and harbour basin
- The reed channels and birdlife of the Köyceğiz–Dalyan delta
- The sulphur mud baths and open-air thermal pool
At Iztuzu beach:
- The ~4.5 km sandbar dividing the river from the open Mediterranean
- Protected loggerhead (caretta caretta) nesting grounds
- The sea-turtle rehabilitation centre (DEKAMER) near the beach
- Shallow, calm water on the river side, sheltered for swimming
- Boat moorings at both the river and beach-road ends of the sand
