Like a little Sardinian Tahiti
Cala Brandinchi is one the way to Capo Coda Cavallo in the San Teodoro municipality. Due to the clarity and color of the sea, the area is known locally as "Little Tahiti." And it's true! If you go during the high-season be prepared for crowds. I went in August and honestly it was too crowded for my liking.
It's a white-sand beach and the sea is so clear that you just want to spend all day there. In the area, you can also explore the shady pine forests and the sand dunes. There are two bar-cafes along the beach, one at the beginning and the other at the end. You can also rent sun chairs and umbrellas if you like.
