Landmannalaugar is famous for its hiking trails. The most popular routes include the 2 hour hike through the Laugahraun lava field to Mt. Brennisteinsalda (Sulphur Wave), the 1-hour hike up Mt. Bláhnjúkur (Blue Peak) and the 4-hour hike to Ljótipollur crater lake (Ugly Puddle). Landmannalaugar can also be the starting point of several longer hiking trails, such as the 3- to 4-day Hellismannaleið route at the base of the Hekla volcano and Sprengisandur route for hikers prepared to travel through the volcanic desert.
