The Tomasee lake (Romansh "Lai da Tuma") is located in a nature reserve at the foot of Piz Badus. At 2344 m above sea level it is the highest point in the Surselva region. From its source the Rhine flows over boulders and between limestone rocks through the Surselva region, passing the bizarre eroded landscape of the Rhine Gorge, also known as the "Swiss Grand Canyon", before joining up with the Hinterrhein (Posterior Rhine) in Reichenau
