Hike through the forests around Flims and cool off with a swim in the clear, sparkling waters of Lake Cauma and Lake Cresta, both less than an hour from Chur, the capital of the canton of Graubünden. The striking landscape that separates the two lakes is the Ruinaulta, often called the Swiss Grand Canyon for its steep, wooded gorges and dramatic cliffs.
