The Fimmvörðuháls Trail is one of Iceland’s most dramatic day hikes, connecting Skógafoss waterfall to the Þórsmörk valley. The route takes hikers between glaciers, across raw volcanic terrain, and past dozens of waterfalls.
Fire and ice shaped every metre of this trail — and you feel both the whole way.
Route Overview
- Distance: 25 km
- Duration: 10–12 hours
- Difficulty: Difficult
Waterfall Section
The hike starts at Skógafoss and follows the Skógá River upstream, ticking off over 20 waterfalls along the way. It’s a relentless procession of cascades, and easily one of the most scenic stretches of trail in the country.
Volcanic Highlands
Climb high enough and the greenery drops away entirely. You’re left on a stark volcanic plateau wedged between the glaciers Eyjafjallajökull and Mýrdalsjökull — a landscape that looks like it was assembled yesterday, because in geological terms, parts of it were.
The Magni and Móði craters, born during the 2010 eruption, sit right along the route and are well worth a slow look.
Descent into Þórsmörk
The trail’s final section drops steeply into a lush valley of birch forest and glacial rivers. After hours on the barren plateau, the contrast is almost disorienting — in the best possible way.
Best Time to Hike
Late June to September is the window most hikers aim for, when snow levels are manageable and the trail is at its most accessible.
Essential Tips
- Start early for daylight safety
- Wear layered waterproof clothing
- Bring food, water, and navigation tools
Conclusion
The Fimmvörðuháls Trail packs a lot into one day — waterfalls, glaciers, active volcanic craters, and a descent into one of Iceland’s most sheltered valleys. Few hikes in the country offer that kind of range.
