Founded in 1914, Swiss National Park is the oldest national park in the Alps and central Europe, and Switzerland's only national park. It is famous for its alpine plants--such as the edelweiss, a protected flower that grows thousands of feet above sea level and was immortalized by "The Sound of Music"—and alpine animals, like the chamois, deer and marmot. Its 80-kilometer network of trails makes this park a hiker's paradise.
