Norway By the Gutulsjøen Lake

The Gutulia National Park is the smallest Norwegian national park, also bordering Sweden. You can walk freely in the park, but there is only one way in. From a hikers' car park, which is also suitable as pitch for the night, at Lake Gutulia, an approximately three-kilometre-long hiking trail leads just into the park.
The lake and forest along this trail are wildly romantic.
