This is a nice beach with pebbles and sand located in western Samos, not to be mistaken for the other Psili Amos to the east.
The beach consists of sand/pebbles, the sandy part is popular and will fill up quickly. You will find sunbeds etc on the beach and there are a few tavernas and a hotel, The Blue Horizon, nearby. The path down from the main road is quite steep.
In the south west part of Samos, follow the road through Votsalakia and you can't miss it.
