It is a protected wetland with abundant fauna and flora. It’s fairly rare to find wetlands on Greek islands and it is characteristic of the special tradition of Skiathos.

Tsougrias

Opposite Skiathos island there’s a group of small islands with Tsougrias being the most seen of them. There is a small snack bar on the side of the island which sell sandwiches and Refreshing drinks. Daily tours run from Skiathos Town and most visitors prefer These islands to get a nice swim in the turquoise shallow water and the tranquil atmosphere.
