Template:Samothraki or Samothrace is an island of Greece at the North. This is less touristic island of Greece so if you are looking for a calm place to stay it can be a good choice. You can get there by ferry from Alexandroupolis (ticket cost 10-15€). There are a lot of good sideviews (lonely beaches, waterfalls).
Accommodation and Sleep
There are some camping on the islands where you can stay (one of those is even free of charge - you check it by the presence of hippies who are living there). But normally you don't need to look for a clamping place because all what is needed can be found at island: there are showers on the beach near the cities; you can wildcamp in every beach (it's safe) f.e. "Kypos beach" is a pretty good one for that.
