From Höfn, Glacier Jeeps (478 1000) focus on trips to one of the nearby glaciers descending Vatnajökull. Base camp is the snowline at Jöklasel hut, some 45km west of town along the Ringroad and then 16km up the four-wheel-drive-only Route F985. From here you mount a skidoo and drive out onto the glacier, tearing across a frozen, empty horizon at upwards of 40km an hour. The usual destination is Brókarbotnstindur, a sharp-edged nunatak with great views west across a deep valley to more tall peaks and ice. Warm clothing, crash helmet and full instruction are provided (bringing sunglasses is a good idea).
For a different take on glaciers contact Ice Guide (661 0900), who offer two hours’ kayaking on a glacial lagoon and, in winter only, ice cave exploration; Glacier Trips (glaciertrips.is) take you out on full-day glacier hikes. Finally, Fallastakkur (478 1517) make four-wheel-drive trips into Lónsöræfi.
