Snorkeling in Finland
Including Lake Pyhäjärvi (Tampere), Lake Saimaa (Savonlinna), and Lake Vesijärvi. On the map.
The vibe
Snorkeling here is a niche pursuit, as the Baltic waters are often brackish and visibility varies significantly depending on the weather. You are looking at a cold-water experience that requires a thick wetsuit even in the height of summer. It is a solitary, exploratory activity that feels far removed from the typical tropical holiday scene.
