Lag Prau Pulté

Highlight • Lake

The lake has no surface inflow. It drains in the fall and remains empty in the winter. At some point during the snowmelt in the spring, it begins to fill through an underground inflow. When it's full, it feeds the Lag Prau Tuleritg through an above-ground outflow, which then has only an underground outflow. This is a peculiarity, and in the spring, it's impossible to predict exactly when it will fill.

Lake Prau Tuleritg

Highlight • Lake

This lake always dries up by the end of the summer due to the seepage of water underground as the lake has no outlet. Every year with the onset of snowmelt, the lake is refilled by meltwater from the mountains above.

There is no tourist infrastructure at the lake and access from the shore is usually very difficult. Unfortunately, swimming is not possible here. Overall, however, the lake is beautifully embedded in the landscape, and a visit to this beautiful and quiet spot is highly recommended.

Lake Cauma

Highlight • Lake

One of the most beautiful mountain lakes in Switzerland. Best to visit early in the morning and during the week, otherwise very crowded with people. Unfortunately, the steep access to the lake is also child's play via the train.

Cresta Lake

Highlight • Lake

Lake Cresta, with its crystal-clear water, is nestled between dark fir trees – a picture straight out of a fairytale. It is a spring-fed lake whose water flows underground, while the outflow into the Flem River is above ground. Due to constant exchange, the entire volume of water is renewed within three days and is always drinkable.

Lake Cresta is only accessible on foot; from the Trin Mulin parking lot (village center), a stroller-friendly hiking trail leads to the natural pool. There is a restaurant at the lake.

Opening hours of the natural pool: During the summer season, depending on the weather, approximately mid-May to mid-September.
Admission to the natural pool: Adults CHF 7, children (6 to 16 years) CHF 3.

The first two lakes were almost completely dry, with only a puddle in each. Lake Cauma has very little water. It was a beautiful tour.

Start at the “Flims Waldhaus Camping” bus stop on the 081 bus from Chur (tip: take the express, which saves the village stops at the beginning). Back from "Flims Waldhaus Caumasee", but also go to the original bus stop or many others on the bus line.

The hike begins in Flims Waldhaus, where there are plenty of parking spaces. Almost without exception, you walk on gravel paths/trails in the shade through the forest. 💦1st lake: Lag Prau Pulté: Small and cute, can be walked around in a few minutes. 💦2nd lake: Lag Prau Tuleritg: less worth seeing 💦 3rd lake: Caumasee: very beautiful, touristy. Fenced in; without an entrance fee you can "only" walk past outside. 📍 Excursion restaurant Conn 📍 Observation platform "Il Spir" 💦 4th lake: Crestasee: wonderful for swimming (7Fr. entrance fee) 📍Felsbachschlucht
