Snorkeling in Greece
Including Kleftiko Bay, Marathi Bay, and Paleokastritsa. On the map.
The vibe
Snorkeling here feels like drifting through a submerged archaeological site, where the clarity of the water makes every rock formation feel ancient and deliberate. Late spring through early autumn provides the best visibility, as the water warms and the winds settle down. It is a casual, DIY affair where you simply walk off the shore and find yourself surrounded by small, curious silver fish in the shallows.
