Scenic lake with shelters and fire pits – perfect for a break, swim, or camping. Plenty of spots around Trehörningen, even for bigger groups.

There is a cliff here and a small area separated from the main path. It offers a great view of the lake as well as ample space for pitching tents as well as trees for hammocks.

Shelter with fireplace just next to the main hiking path. Not really any other amenities, and there are reeds growing along the water, so it is not really a swimming spot.

Besides just parking, there is an outhouse, a water pump, as well as a fireplace and several sets of tables and benches here. It is a good starting point for a lot of trails throughout the Paradiset area.
