The Swiss National Park is located in the canton of Graubünden in the east of Switzerland between Zernez, S-chanf, Scuol and the Fuorn Pass in the Engadin valley on the border with Italy. It is part of the worldwide UNESCO Biosphere Reserve.
As of 2009, it is the only National Park in Switzerland, though there are plans to create more. It has an area of 174.2 km² and is the largest protected area of the country. It was founded on 1 August 1914, the national holiday of Switzerland. It was one of the earliest national parks in Europe.
In the park, one is not allowed to leave the road, make fire or sleep outside the Chamanna Cluozza; the mountain hut located in the park. It is also forbidden to disturb the animals or the plants, or to take home anything found in the park. Dogs are not allowed, not even on a leash.
A visitor centre is located in Zernez. The road through the park leads over the Fuorn Pass (or Ofenpass) to South Tyrol in Italy.
