Lag da Breil

Lag da Breil (German: Brigelser See) is a small lake on the eastern edge of Breil/Brigels in the Swiss canton of Graubünden, in the Surselva region. At 1,255 m above sea level and roughly 500 m long, it is known for its turquoise water and sits close enough to the village to reach on a short stroll.

Where is Lag da Breil and how do you get there?

The lake lies east of the built-up area of Breil/Brigels. Its name is Romansh, the language spoken in this part of Graubünden. Drivers can reach the car park and resort at the western end. On foot, start at the Postplatz in Brigels: the route heads towards the golf course, passes a playground and mini-golf, follows the shore and returns to the village. It is about 2.7 km, takes around 45 minutes and climbs only 47 m. The path suits strollers.

What is there to see and do?

Walking once around the water takes about 20 minutes. The south side has mini-golf and a tennis court, and you will find a playground and food stops nearby, including a kiosk at the bathing area. Most visitors stay in the village and come for a short walk. Cyclists can ride a demanding 26 km Brigels – Lag da Breil loop, while an easy 9 km route leads from Waltensburg towards the lake.

Can you swim in Lag da Breil?

The official Surselva tourism page says the lake's water is used to generate electricity, so bathing is not allowed, and Komoot contributors also advise against swimming. For a dip, use the separate bathing lake nearby. It is about 35 m wide and up to 1.60 m deep, with solar collectors warming the water to 20-22 degrees. It has a children's pool, a grassy area with fire pits, changing rooms, toilets, showers and a snack bar. Dogs must stay on a lead at the lake and may not enter the water.

When should you visit?

Summer is best: the bathing lake is open and the paths are dry. At 1,255 m, mornings can be cool even in season. Check current bathing rules with the region before you travel.
