Mariehamn is a relaxed, walkable capital, but some of Åland's best experiences lie just beyond its edges. Whether you travel by bike, car or small ferry, a day trip opens up medieval ruins, dramatic viewpoints, sheltered fishing bays and local island culture that you cannot find in town. Here is what to explore.
Historic Sites Worth the Journey
Two landmarks stand out for anyone interested in Åland's history, and both are easily reached from Mariehamn.
- Kastelholm Castle dates from the 14th century and was first mentioned in records in 1388, making it one of the oldest surviving structures in the archipelago. It sits in the municipality of Sund and gives a vivid picture of medieval power in the Baltic.
- Bomarsund fortress, also in Sund, tells a more dramatic story. Construction began in 1832 as a major Russian imperial fortification. It surrendered on 16 August 1854 during the Crimean War and was blown up by allied forces on 2 September 1854. The atmospheric ruins remain spread across the landscape and are free to wander.
Visiting both sites in a single day is comfortable by bicycle or car. Check local tourism information for opening times and any guided tour options, which can vary by season.
Nature, Views and the Outdoors
Ramsholmen nature reserve, located in Jomala close to Mariehamn, is one of the easiest escapes for a few hours of coastal walking among traditional Ålandic meadow landscape. It requires almost no travel time and suits all fitness levels.
For something more ambitious, head north to Getabergen in Geta municipality. At approximately 107 metres above sea level, this is one of the highest points in the archipelago and rewards the short climb with wide views across the surrounding islands and open water. The terrain is rocky and forested, which is as dramatic as Åland's largely flat landscape gets.
Cycling is one of the best ways to explore beyond Mariehamn. Åland has an extensive network of quiet roads and dedicated cycling routes connecting municipalities, ferry links and nature areas. Bike rental is available in Mariehamn — ask at local hire shops or your accommodation for current options and route maps.
Fishing and Local Flavour
Åland's waters offer genuinely rewarding fishing. Common species include pike, perch, pikeperch, whitefish, sea trout, Baltic herring and flounder. Pike fishing is at its best in spring and autumn in sheltered bays and reed beds, while perch can be caught throughout the season from shore or jetties. Many fishing waters are managed by local fishing associations, so always check access before casting. Fishing permits for Åland are handled through fiskevard.ax — this is entirely separate from the mainland Finnish permit system. Children under 18 and adults over 65 are exempt from the permit requirement for rod fishing.
For a taste of local brewing, Stallhagen brewery in Grelsby, Finström was founded in 2004 and produces beers using Åland ingredients. It makes a natural stop on the road between Mariehamn and the historic sites of Sund, and pairs well with a castle visit on the same day.
