It's situated in the east of Switzerland, in the canton of Graubünden At nearly 175 square km, the Swiss National Park is the largest protected area in the country.
Restrictions in the park are quite tight, with it being forbidden to disturb the animals or pick any flowers or plants, and dogs are not allowed in the park, even if they are on leads.
