Fimmvörðuháls is the pass between the Eyjafjallajökull and Mýrdalsjökull glaciers, and the trail over it is the one hike everyone who visits Iceland in summer should do. You start at the top of Skógafoss and follow the river up past waterfall after waterfall, cross a high plateau with snowfields, walk over the lava that erupted in 2010 (still warm in places), and then drop steeply into the green amphitheatre of Þórsmörk.
It's long. You need fitness and some stubbornness, and a weather window — we run it only on decent forecasts, July and August. The reward is absurd: glaciers left and right, a new volcano under your feet, birch woods at the bottom.

Level 4. 25 km, 1,000 m up, 800 m down, 10 hours. If you regularly hike long days you'll love it; if your longest hike is 10 km, train first or do Esja and Landmannalaugar.
We cancel the night before on a bad forecast — full refund or free rebooking. On the pass, the guide can turn the group back to Skógar.
