Aland Archipelago
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.
What would you like to do in Aland?
Start with the experience, then find the right place for it. Conditions and access vary between destinations.
The waters off Mariehamn and the southern and western skerries are a specialist wreck-diving destination. Wooden Nederland, iron-hulled Plus and deeper technical targets are best approached through a licensed local operation such as Divealand. The more distant eastern archipelago is a ferry-and-nature region, not a documented substitute dive center. Every breathing-gas scuba outing requires the applicable Aland Government authorization, and individual sites may have further restrictions.

Things to do in Aland Archipelago
Planning your trip
Use Aland Archipelago for the country-specific dive map and treat linked site records as research leads, not booking confirmation. Ask a Mariehamn operator for the exact permitted wreck, maximum depth, site exclusions, group size, conditions, fill gas and departure dock. An operator's published wreck list does not establish a guaranteed outing. Build in a backup weather day and an adequate no-fly interval.
Conditions and timing
- Best window
May - June and September - October for experienced wreck divers; June - August for mixed trips
Expect variable visibility, suspended sediment and cold thermoclines; deep Baltic water can remain around 4°C. Boat exposure, fishing gear, shipping channels and fragile wreck parts add risk. Drysuit competence, suitable gas, redundant lighting and rescue support may be necessary. Do not enter wrecks or use recreational qualifications to justify technical depth.
