Remarkably preserved Baltic shipwrecks, specialist day boats and island maritime history.
Overview
Aland is a cold-water wreck destination, not a tropical reef getaway. Wooden schooners, iron sailing vessels and deep technical wrecks lie in brackish Baltic waters, where preservation has been helped by low salinity and strict heritage protection. The official Aland tourism guide says scuba visitors need government authorization, normally arranged through a professional guide. The Mariehamn-based Divealand offers weather-planned day outings, including possible two-dive days. The best combined holiday months are generally June to August; specialist divers may also prefer spring or autumn visibility when itineraries and conditions permit. Non-divers can enjoy the Maritime Museum, Pommern, kayaking, cycling and sandy beaches. Expect cold depths, shifting visibility and permit restrictions. Confirm current charter availability and the exact wrecks covered before buying ferry or airline tickets.
Brackish Baltic conditions and legal protection preserve distinctive wooden and metal wreck structures. See the official wreck overview.

A local operator separates roughly 0 to 35 m recreational listings from deeper technical and expedition categories. The list is not a promise of access or a personal depth clearance.
Non-divers can enjoy a maritime museum, historic sites, beaches, kayaking and sauna without joining the dive boat.
