More ways to explore the area's outdoor wonders
You step out of the van in Kollafjörður and the mountain that frames Reykjavík rises like a gray door, jagged ridges slicing into the cold light. The trail follows the Mógilsá drainage at first, then tightens into scree and stone as it climbs toward Þverfellshorn. Wind tests your balance; stone underfoot dares you forward.

Wear grippy boots
Upper slopes are loose scree and slabs—sturdy hiking boots with good tread reduce slip risk.
Layer for wind
Windproof outer layers and a warm mid-layer make summit stops comfortable even on clear days.
Carry more water than you think
Guides provide water, but smaller groups and effort on the ascent mean you should carry at least 1–1.5 L.
Watch the weather window
Iceland weather can change fast; start after checking forecasts and plan extra time for descent in poor conditions.
Sturdy hiking boots
Provides ankle support and traction on scree and rocky slabs.
Windproof jacket
Blocks cold gusts exposed near the summit and keeps core temperature stable.
Daypack with 1–1.5 L water
Carries water, snacks, layers and basic first aid for a 4–5 hour outing.
Trekking poles
Helpful on steep descents and loose scree to protect knees and improve balance.
