Why sailors love Åland
The Åland archipelago is one of the most popular boating areas in the Baltic. More than 6,000 islands, islets and skerries create a seascape where you can choose between sheltered channels between green islands and open stretches of water where the wind picks up. Distances between harbours are short, the scenery is beautiful and there is always another bay to explore. Åland also sits right between Sweden and Finland, making the islands a natural stop for anyone crossing the Sea of Åland or sailing on towards the Archipelago Sea.
When to go
The boating season runs in practice from May to September. July and early August are peak season, with the most boats in the guest harbours and the best chance of settled summer weather. Around Midsummer the days are almost endless, which makes evening sailing an experience in itself. June and late August are quieter and suit those who want the harbours more to themselves – but expect cooler nights and colder water.
Guest harbours and natural anchorages
Åland has a well-developed network of guest harbours, from Mariehamn with full services to small village harbours in the archipelago with a jetty, a sauna and a kiosk. Mariehamn is the natural place to provision and find services. Out in the archipelago municipalities – such as Brändö, Kökar, Kumlinge and Föglö – you will find quieter harbours with a completely different atmosphere.
Many sailors also prefer to anchor in sheltered natural harbours. Show consideration for residents and for birdlife: some areas are closed to visitors during the nesting season, and you should never moor at private jetties without permission.
Navigation and safety
The archipelago is full of shallows and submerged rocks, so up-to-date nautical charts are essential. Official charts for Åland waters are published by the Finnish Transport and Communications Agency (Traficom) and are available both in print and in navigation apps. Never rely blindly on a plotter – stay in marked channels and keep a margin from the shallows.
- Check the forecast every morning. On open stretches and the Sea of Åland, conditions can become rough quickly.
- Life jackets should be on board for everyone and worn by children.
- Give way in narrow sounds – the large passenger ferries have limited manoeuvrability and must always have a clear path.
- Refuel in good time – fuel is not available in every harbour, especially in the outer archipelago.
Renting a boat or bringing your own
Many visitors arrive in their own boat from Sweden or mainland Finland. If you want to rent, charter options exist on Åland, both skippered and bareboat – ask the tourist information office about current operators. Bareboat charter usually requires documented experience. If you have little boating experience, you can explore the archipelago by kayak or on the public ferries instead; see our guide to kayaking on Åland.
Experiences along the way
Combine your sailing with swims from the rocks, fishing in quiet bays and visits to the archipelago's lighthouses. Our guides to fishing on Åland and lighthouses in the archipelago offer inspiration.
