Most hikers come to Landmannalaugar to start (or finish) hiking the Laugavegur trail. But if you're only visiting for a short time, there is a wonderful and short 4-km loop trail at Landmannalaugar with absolutely breathtaking sights, without the time and commitment of a long-distance backpacking trip. As other reviewers have said, the best way to experience this area is backpacking the entire trail. But if that's not possible, it is still definitely worth a visit for a short time. We visited Landmannalaugar on a day tour with Iceland Guided Tours and only had about 2 hours here. After quickly eating lunch, the tour guide warned us that it could take up to 2 hours to hike the loop, but we assured him we could finish it in time. The loop starts following the Laugavegur Trail behind the huts up into the Laugahraun lava field and proceeds mostly west until it comes out in the most beautiful valley surrounded by the lava field on one side and multi-colored rhyloite mountains on the others. Although most of the area is devoid of life, this valley was full of green grasses and small white wildflowers. From here, the trail turns south and heads towards Mount Brennisteinsalda (sulphur wave). It's easy to tell that this volcano is still active from the numerous fumaroles spewing sulphurous gases. Quite beautiful, but not the most pleasant smell. The Laugavegur Trail continues up the volcano, while the Grænagil trail turns east and heads back into the lava fields. This trail goes through the lava fields and into the namesake gorge, formed by a river flowing between Mount Bláhnúkur and the lava fields. The river is quite small so the gorge is very narrow, but quite beautiful. The trail winds down into the gorge with side trails heading up Blánúkur and approaches the river as it exits the gorge. From here, the trail turns north and heads back to the camping area. We finished the hike in just over an hour, with taking many pictures, and still had time for a quick dip in the hot springs before our bus was getting ready to leave.
