Lake Sørvágsvatn is the largest Lake in the Faroe Islands, which ends in a spectacular waterfall out to sea. A rough path runs parallel the lake, and you can take a short detour to the edge of some cliffs for some pretty awesome sights (not advised for those who fear heights!). Be sure to keep an eye out for WWII relics and the ubiquitous sheep!
The hike took about 3-4 hours; however, we stopped for a long time near the waterfall for a picnic lunch. To get there, drive past the police station in Miðvágur onto a gravel road, up a small hill and park next to a small gate.
