The Part 10 Lakes Hike passes four of the lakes.
The Obersee is situated at 1'739 m.a.s.l. and is the larger of the two lakes in the middle of the development area of Arosa. Numerous waterfowl and reed birds, as well as diving ducks and most European swimming ducks can be found on the Obersee.
The Lower Prätschsee is situated at 1,910 m.a.s.l., a bit below the Upper Prätschsee and a bit hidden, but accessible via a narrow path.
The Scheideggseeli is located at 2,080 m.a.s.l. in an alpine pasture in the alpine zone at the Scheidegghalde. Wild ducks breed at this lake from time to time, although the secluded water body offers no natural protection for the clutch.
The Upper Prätschsee is located at 1,987 m.a.s.l., as the name suggests, in the Prätsch area. A fireplace with wood is available for everyone at the lake.
The board for the 10-Lake-Plausch is placed at the outflow of the lake.
