Remarkably preserved Baltic shipwrecks, specialist day boats and island maritime history.
Pick an activity mode to compare signature sites, skill fit, and gear planning notes before you lock your trip.
Divealand runs local, weather-dependent boat outings from its Mariehamn base and groups named wrecks by recreational and technical depth. The attraction is unusually preserved maritime heritage, not easy shore-entry reefs. Government authorization, actual permit boundaries, cold-water skills and each wreck's depth are non-negotiable.
