Nuuksio National Park is Espoo’s great natural treasure, a protected wilderness of ancient forests, clear lakes, bogs and rugged hills that is home to the elusive Siberian flying squirrel. Crisscrossed by marked trails, campfire sites and duckboard paths, it invites hiking, foraging, swimming and wild camping under Finland’s everyman’s right. Enjoying it responsibly, by keeping to trails and leaving no trace, protects this fragile landscape, making a visit both a wonderful escape into nature and a lesson in sustainable outdoor life.
