Look for the gravel lot off Route 862, north of the Ring Road – Dettifoss marks the spot where the paved road ends and lava fields open up. Most people approach from the west side; the trail starts here, marked and mostly flat, winding over black volcanic rock. The falls come into earshot before they’re in view, and the walk from the lot takes about 15 minutes at a steady pace.
Dettifoss is the largest waterfall in Iceland by volume – about 100 meters wide and 44 meters high – with a reputation for being among the most powerful in Europe. Two viewing platforms sit on the west side. The upper one gives a wide look over the falls and canyon; the lower platform cuts in closer for a direct view, often shrouded in mist that soaks jackets and fogs camera lenses. On some days, the lower platform is closed off if the ground isn’t stable, but the upper spot stays accessible.
The ground near the falls vibrates underfoot. In winter, everything can freeze over – the rock gets slick and locals often bring walking sticks or microspikes. Both platforms are fully exposed, so wind and spray are a constant, even in summer.
From the main trail, a side path heads upstream to Selfoss, a broad cascade framed by cliffs. It’s a short walk, though the trail ends before the main drop. Hafragilsfoss is farther downstream, with its own lot about 2.5 kilometers north.
Some days, a food truck parks up by the west lot, serving hot dogs and soup. The rest is bare bones: marked paths, viewing platforms, and the river’s roar. The whole area is wide open – rock, water, and sky – nothing between you and the edge but the sound and spray.
