Get to know the place
Åland is an archipelago of Finland where Swedish governs the names on signs. Mariehamn, its administrative center, occupies a strip of land between two harbors. The maritime museum presents the islands’ relationship with navigation, complemented by the quay and sailing-boat scenery.
On the main island, Kastelholm lets you visit a medieval castle, while Bomarsund features the ruins of a 19th-century fortress. Both sites are in Sund and make a road itinerary from Mariehamn. The smaller islands require attention to ferry connections.
Plan arrival as part of the trip: the ferry offers Baltic views but has its own duration and disembarkation port. A bicycle covers chosen routes depending on distance, while bus and car help for longer transfers. Check museums’ schedules before allocating days.
This destination brings together 1 city: Mariehamn.

Before you go
A little planning leaves more time to enjoy the journey.
From May to September there are usually more visits and tourist crossings. Between December and February winter typically brings cold and short days.
The seasons shown are the most usual ones; nature doesn't always follow the calendar.
Three days allow you to see Mariehamn and reserve a day for Sund. Add nights if you want to cross to other islands without relying on multiple connections in one day.
Mariehamn makes access to museums, dining and many departures easy. A rural base can work if you have transport; check the distance to the arrival port and to the day’s last service.
Take your trash with you, follow the signs and support local businesses. In natural areas, follow the visiting guidelines.
