1. Laugavegur Trail
Location: Landmannalaugar to Þórsmörk
Duration: 4–5 days | Distance: ~55 km
If you are looking for the best trek in Iceland, most people will point you straight to the Laugavegur Trail—and for good reason. This legendary multi-day hike takes you through rainbow-colored mountains, lava fields, steaming vents, and lush valleys. It is like walking through a series of fantasy worlds, each more surreal than the last. Stay in mountain huts or bring your tent for the full experience.
2. Fimmvörðuháls Pass
Location: Þórsmörk to Skógar
Duration: 1 day | Distance: ~25 km
This is one of the most dramatic one-day treks you will ever do. Fimmvörðuháls cuts between two glaciers—Eyjafjallajökull and Mýrdalsjökull—offering a mix of volcanic landscapes, waterfalls, and panoramic views. The trail passes by two craters formed in the 2010 eruption, making it a walk through living geological history. Many hikers combine this with Laugavegur for an extended adventure.
3. Hornstrandir Nature Reserve
Location: Westfjords
Duration: 2–7 days | Distance: Variable
Remote, wild, and untouched—Hornstrandir is Iceland at its most raw. There are no roads or permanent settlements here. What you will find: towering sea cliffs, arctic foxes, wildflowers, and silence. Lots of silence. This is not just one of the best treks in Iceland—it is one of the best in all of Europe for those seeking solitude and unspoiled nature. Access is by boat in summer only, so plan ahead.
4. Glymur Waterfall Hike
Location: Hvalfjörður (just north of Reykjavík)
Duration: 3–4 hours | Distance: ~7 km round trip
Glymur used to be Iceland’s tallest known waterfall, and the hike up to it is an adventure on its own. You will cross a cave, wade a shallow river, and ascend alongside a stunning canyon. The views from the top are well worth the effort. This rewarding half-day hike is ideal for those staying in Reykjavík who want to experience the country’s natural beauty without venturing too far. Its accessibility and stunning scenery make it one of the most beloved hiking trails in Iceland.
5. Reykjadalur Hot Spring Valley
Location: Near Hveragerði (South Iceland)
Duration: 2–3 hours | Distance: ~8 km round trip
Short, scenic, and with a built-in spa break—what’s not to love? Reykjadalur, or “Steam Valley,” is a gentle hike that winds through geothermal landscapes to a natural hot river where you can bathe surrounded by green hills and rising mist. Ideal for families, couples, or anyone who wants to combine hiking with pure relaxation.
