Fårö is a small island just north of Gotland.

The island is known for its beaches and "rauks" along the coastline.

Main goal with the route is to run around the whole island of Fårö. 

For the most part you will be able to have the coastline on your right (or left side depending on the direction you start in). Some areas along the coast are private property and there you need to diverge from the path.
