In the middle of Brigels, next to the Pradas Resort, lies the naturally landscaped swimming lake. The small lake is a maximum of 1.60 m deep and is pre-warmed to a pleasant 20–22 °C by solar panels. The entrance is free. Around the lake, there is a sunbathing lawn, a barbecue area with seating, as well as showers, changing rooms, and toilets. For families, there is also a paddling pool and various play and leisure facilities. A nice way to cool off on warm days after a hike – although the swimming lake, due to its location near the resort, already appears quite touristy and family-oriented.

The Lag da Breil, in German Brigelsersee, lies at around 1,255 m above sea level, directly above Brigels. The lake, approximately 500 meters long and up to 140 meters wide, was created as a reservoir in 1946 and is used for energy production. The Flem feeds and drains the lake. Despite its function as a reservoir, the Lag da Breil appears very idyllic and blends beautifully into the landscape around Brigels. A pleasant walking path leads all the way around the lake. Important: Swimming is not allowed in the reservoir.
