There are three beaches with the name of Psili Amos (meaning fine sand) on Samos.
The best known Psili Amos is a fine sandbeach in the southwest of Samos, close to Pythagorion. The sea isn't very steep when you go into the water and therefore you must walk a bit into the sea to reach deeper water. That is of the reasons why the beach is popular with families with small children. On beach there are taverna's and you can there also rent sunbeds and parasols.
another Psili Amos beach is also situated in the south, a little bit east of Limnionas on the other side of the island (see pictures). I once read somewhere that someone described it as a small sand beach, but actually it is quite a large sand beach. On part of the beach there are umbrellas and sunbeds for rent and the rest of the beach is for people with beachtowels: there is plenty of room for everybody.
