Psili Ammos is a beach in the southern part island of Thassos, near Potos. Its name means fine sand.
The beach is 250 meters long with very fine sand. There are no rocks around the shore so you can walk safely without aqua shoes but sometimes there are strong waves. In some places the sea floor goes deep suddenly, so be careful in the water, especially with children. There is a beach bar with restaurant and sunbeds. Some water sports are available. There is one volleyball court and a mini market.
In July and August it gets crowded since it is very close to Potos and is known as one of the most beautiful beaches on Thassos.
