Länsi Mustasaari is the wildest island of Suomenlinna. Many bare rocks areas, several cliffs and small vegetation on the ground. Atypical relief due to the fortification system of Suomenlinna. Some private areas.

Please respect private areas, forbidden areas, dangerous areas (impassable cliffs) and the nature (bird nests and flowers). Avoid spike shoes.

The course is 2,3 km with a flip map over. There is no flags on the terrain.

Map has been made in April 2024. You can also order the map without courses.

Susisaari is coming soon. Stay tuned !
