The Tjusträsk bird tower offers a view of the lake, the reeds along the shore, and the farmland landscape of Siuntio. The tower is a BirdLife Lohja–Siuntio observation site used to monitor waterfowl and migratory birds. In the fall, the area is particularly known as a resting place for cranes. To reach the tower, take Lepopirtintie: park your car in the recreational area’s parking lot and continue on foot along the Högbacken trails to the lake’s northern shore. The arrival address directs you to the area, and the map marker shows the tower itself. Visitors explore the site on their own; no specific weekly visiting hours have been set. Contact information is for the chairperson of BirdLife Lohja–Siuntio, which manages the site, not for the staff on duty at the tower.
