Swiss National Park

The oldest national park in the Alps, founded in 1914, in the Engadine valley of eastern Switzerland. It's a strictly protected wilderness where nature is left to itself, home to red deer, chamois, ibex, marmots and bearded vultures. You must stay on the 21 marked trails.

The visitor centre in Zernez explains the park. The walk to the Macun lakes and the trail through the Val Trupchun, famous for red deer in autumn, are favourites. Entry is free; it's open from June to October.
