Tlos is one of the great Lycian sites and one of the most visually impressive — a massive acropolis rising from a crag above a wide valley, scattered with rock-cut tombs, an agora, baths, a theatre, and the remains of an Ottoman fortress built over the ancient citadel. The site is large and requires some scrambling to explore properly.
The rock tombs here are carved into the cliff face below the acropolis, several with elaborate carved facades. The most famous is the Tomb of Bellerophon, which depicts the mythological hero riding Pegasus. The site is about 45 km from Fethiye — reachable by car or on an organized day trip, often combined with a visit to the Saklıkent gorge nearby. Allow three to four hours.
