Although small, this island situated to the south of Nisyros captures the imagination of anyone interested in paleontology, for here there once lived a prehistoric dwarf elephant, whose skeletons were found in one of its caves.
The capital of Tilos is Megalo Horio (literally Big Village), located in the interior to the north of the island. It is built like an amphitheatre on a hillside, topped by a ruined castle erected by the Knights. The village occupies the site of the ancient town, whose remains can still be seen scattered among the houses.
Some 2.5 kilometres west of Megalo Horio, you can visit the monastery of Agios Antonios, while 6.5 kilometres to the northwest is another monastery with guesthouse - dedicated to Agios Panteleimon. Lush greenery surrounds this walled 18th century edifice Tilos's main port is Livadia, southeast of Megalo Horio. The island's best beaches are at Livadia, Agios Antonios, Plaka and Erysto (2.5 km from Megalo Horio).
