Alajuoksu

Alajuoksu is a scenic Baltic Sea dive site in the Southern Finland archipelago, offering beginner-friendly exploration along granite rock formations typical of the Finnish coastline. The site features shallow reef areas where divers encounter perch, pike, and Baltic herring moving through clear northern waters. Bladderwrack seaweed covers the rocky substrate, creating habitat for invertebrates and small fish. Summer months provide the best visibility and water temperatures around 15-20°C at the surface, making this an accessible introduction to Finnish diving.
