There is a parking lot near a hiking trail, located close to a substation. The trail is mostly flat and there is no traffic during the nighttime after the guards have changed, so it is peaceful and quiet. Along the western trail, there is a lake around 200 meters away.
We spent our first night here in early September after taking the ferry, as the spot by the lake was already taken. It was totally fine and you can enjoy a nice walk to the lake. Just be aware that you can hear the nearby power lines quite loudly.
