Djúpavatn - Sog - Trölladyngja - Grænavatn - Krókamýri

Technically demanding sections and one or two hiking bits. Gravel roads lead to both sides of the mountains so the trip can start by either Djúpavatn or Sog. The tack follows old jeep tracks, some single track and gravel roads. Rocky and demanding downhill sections. Counterclockwise is recommended. The trail is scenic and passes through an active geothermal canyon with strange blue clay and crystal needles!
