The beaches in the southern part include Azapiko, Tristinika, Kalamitsi and Kriaritsi.

South, from the harbour's exit there is Kartalia, the most southern part of Sithonia, a very impressive area which puts its visitors under a spell with its rocky secluded beaches.

The main villages in the peninsula are Nikiti, Neos Marmaras, Parthenonas, Sarti, Sykia, Vourvourou and Agios Nikolaos.

In the middle of Sithonia peninsula, near the village of Neos Marmaras, is the holiday resort of Porto Carras; the place of the 2003 European Union leaders Summit.
