When leaving Prêles and heading towards Neuveville, there is a second path on the left after the campsite. This flat area is perfect for having a meal and even spending the night, as there are no restrictions. You can enjoy a view of Lake Biel through the trees.
The location of the accommodation in a peaceful area provided a great night's rest. Although the parking area was surrounded by trees, it did not bother us as we were still able to enjoy nature. The view of the lake was not visible from the parking spot.
Thanks to sylvain57 for creating this helpful place. It's a calm and peaceful location with very little car traffic at night. Just a reminder to pick up any paper (toilet) that you may see. It's a beautiful forest area that needs to be preserved.
