Iceland's Laugavegur Trail runs about 55 kilometres across the southern highlands, from the hot springs of Landmannalaugar to the birch woods of Þórsmörk. Hikers walk it over four days, 12 to 17 kilometres a day, sleeping in mountain huts or at the campsites beside them. The trail passes the sulphur-streaked slopes of Brennisteinsalda, crosses obsidian fields and snow below Hrafntinnusker, drops to the lake at Álftavatn, and ends after the black sand deserts and the cold river fords at Emstrur and Þröngá, which are waded on foot and can rise after rain. 1
Two things shape a trip more than the walking does. The season runs only from late June to early September, when the buses to Landmannalaugar and back from Þórsmörk operate, and every hut or campsite has to be booked before you set off — the trail association says the huts often sell out in peak season. Self-driving visitors must also reserve parking at Landmannalaugar and pay a service fee before arrival between 20 June and 14 September, from 9 AM to 4 PM. 12
The trail association's own description calls it recognised by National Geographic as one of the world's most beautiful, and that is the reputation it carries: a four-day crossing of colourful rhyolite, black sand and glacier views with a hard, wet edge to it. 1
