A turquoise alpine lake (the color is really insane!) perfect for swimming and relaxing by the shore (entry fee required). From Flims Waldhaus, take a short walk or the free funicular down to Caumasee. Walking around the lake takes about 45–60 minutes on mostly flat paths.

What I recommend after enjoying Caumasee is a 40 minute walk to the Il Spir viewpoint, stoping at Restaurant Conn just before you get there. Continue to Crestasee for another swim or SUP stop. The full loop Flims Waldhaus – Caumasee – Il Spir – Crestasee – Flims is about 10 km (3–4 hours). If you want to shorten it, you can take Bus 81 from Crestasee back to Flims – which is what I usually do.

Tips

• Swimming season: June-September, water temp ranges 17–24°C
