Samothraki is a small island that is basically the conical tip of a mountain rising out of the sea. There are two main towns; Kamariotissa and Chora; between them they provide most of the facilities one small town would normally have. There are two campsites. The island is surprisingly lush and green for an Agean Island, due to the rainfall caused by the central mount 'fengari'. The goat population (estimated at approx 100,000) outnumbers the inhabitants by 33 goats to every person.
Due to the fact that the land rises steeply out of the sea, there are not many large beaches with the possible exception of the beach known as 'Fat Sand' which is located at the far end of the island from the main centers.
Samothraki is an ideal place for a rural retreat, it is very unsophisticated and lacks almost all tourist infrastructure (there is no nightlife, except during the annual music festival). The inhabitants are extremely warm, friendly people who will go out of their way to make you feel welcome.
