Telendos is actually nothing but a rock in the sea, only 750m away from the coasts of Kalymnos.
It is a barren and rocky island, except for the plain on the base of the peninsula that is formed on its southeastern side, behind the characteristic traditional settlement extending along the eastern-southeastern beach.
It has a maximum length of approximately 4km, an area of 4.6m2 and a maximum altitude of 460m.
The major capes are Aspros Kavos on the west coast and Pnimenos on the northeastern terminal.
Telendos is accessible by boat and visitors can wander around on foot to discover corners rich in archaeological treasures.
The island’s architecture is a characteristic example of the traditional Dodecanese architecture and the settlement of Telendos has been declared traditional.
