Potami Beach is a long pebble beach with clean waters on Samos Island northeast coast. The beach is accessible by car or on foot from Karlovassi Town. Potami consists of pebbles. When visiting Potami Beach make sure to add a walk by the river up to the famous waterfalls in Island. 

The walk, roughly 2 km, will take you through a lovely forest and eventually ends at a small lake where you can swim, the falls are then straight ahead.
