About Tomasee

Tomasee, situated in the picturesque Swiss Alps, is renowned as the source of the Rhine River. Its pristine alpine environment attracts visitors seeking hiking, natural beauty, and a glimpse of this significant waterway's origins.

Wilderness Landscape & Natural Heritage

Tomasee sits at an elevation of approximately 7,615 feet (2,320 meters) in the Swiss Alps, within the Canton of Graubünden. This small alpine lake is revered as the source of the Rhine River, one of Europe's major waterways. Surrounded by rugged peaks and verdant valleys, Tomasee offers a quintessential alpine experience. Its clear waters and surrounding meadows serve as a habitat for a variety of alpine flora and fauna, including marmots and the occasional eagle overhead. Historically, the area around Tomasee has been used for seasonal pastoralism, and remnants of this traditional use can still be observed. The lake is a popular destination for hikers who often trek the marked trails leading from Oberalp Pass, rewarding them with breathtaking views and the tranquility of the high mountains. Despite its remote location, Tomasee's appeal as a natural wonder and its role as the starting point of the Rhine draw nature enthusiasts and those interested in hydrology alike.
