Castri beach is only 3km from Nikiti and is a great place to escape from crowd. Especially small Castri beach. It is not easy to find it because private homes have completely blocked access, but if you do a little effort, you will see a trail between two private yards leading to the beach.

There is no crowd in August, just some tourists. The sea is crystal clear because there are pebbles on the bottom, not the sand that rises. On the beach there are no sunbeds and sunshades, so it's best to take your own.

The sea in this part has no turquoise color that is characteristic of Sithonia, but it is clear and calm, and sunsets are wonderful. Excellent beach for enjoying peace.
