Marscholsee

Marscholsee is a small alpine lake in the Swiss canton of Graubünden, sitting at 2,053 m above sea level near the San Bernardino Pass, in the Rheinwald area. It suits walkers who want high-mountain scenery without crowds or heavy infrastructure.

Where is Marscholsee?

The lake lies in the Lepontine Alps close to the San Bernardino Pass, the route that links the Hinterrhein valley (Rheinwald) with the Italian-speaking Mesolcina valley. Its coordinates are roughly 46.51° N, 9.17° E. The surroundings belong to a protected moorland landscape, and the name echoes the neighbouring Marscholhorn massif, also known as Piz Moesola. Some sources place Marscholsee alongside the name Lago Marschola and mention a separate small lake, Moesola, nearby. Check a swisstopo map on site to tell them apart.

How do you get there?

The pass is the natural starting point. The pass road is normally open from May to November. In summer, Postauto line 541 serves the pass area, and the village of San Bernardino has a large car park behind the youth hostel. From the village (1,608 m) an old road paved with Roman stones climbs to the pass: about 5 km, under two hours on foot and roughly 500 m of ascent. From the pass summit, the water is a short walk away.

What will you see?

• A high-altitude lake at 2,053 m, framed by pasture and rock.
• Surrounding peaks, including Marscholhorn.
• The nearby Moesola lake, the source of the Moesa river.
• Stretches of Roman paving and a pass route used for centuries.

The lake is stocked with brown trout, so you may meet anglers. Check local Graubünden rules and permit requirements before fishing.

When should you go?

Summer and early autumn are best, when the pass road is open and trails are clear of snow. Weather above 2,000 m changes fast, so pack a warm layer, a rain jacket and sun protection. In winter the pass is closed to traffic and any approach needs snow equipment and experience.

What should you bring?

Sturdy hiking shoes, water and a snack are enough. A restaurant operates at the Ospizio by the pass, but confirm opening hours first. According to tourism listings, the loop from San Bernardino village over the pass and back along the road takes about four hours, covering around 12 km with roughly 600 m of climbing. For longer outings, check the pass forecast, since summer afternoon thunderstorms are common in the Alps.
