Ängsö is located on the west side of the island Ängsö in Mälaren near Ängsö castle. Drive the old E18 to Kungsåra church and turn south towards Ängsö. Follow the road past Ängsö castle to the car park just south of the castle approx. 900m. The car park is a small hidden clearing, unmarked. Walk along the path that starts in the southwest corner of the parking lot (on the left as seen from the entrance). The path is marked with orange paint on the trees, keep to the left/south when the path splits into the forest. After approx. 500 meters of winding forest path, you arrive at the nude pool. The bath has a rocky beach.
