About 3 kilometers north of Sarti, we find Platanisti beach in the Sithonia area on the east side.

Awarded with the blue flag in 2019 it is a beach about 550 meters long of soft white sand both on the shore and as a backdrop. The transparent and turquoise water slopes gently and is suitable for a nice swim or for families with children.

A part is equipped with sunbeds and umbrellas and a beach bar, another free part. In the middle of the beach there is a passage channel that usually dries up during the summer and behind the rocks on the left side there are several smaller bays and a slightly larger one.
