More ways to explore the area's outdoor wonders
You step off the jeep into a steam-laced bowl of color: ochre ridges, black lava scars and sulfur-streaked snow patches frame a valley that seems to breathe. Kerlingarfjöll’s Hveradalir valley challenges the senses with hissing fumaroles, bubbling mud pools and the mineral tang of hot springs — the highlands making themselves known in sound and scent.

History
Kerlingarfjöll sits within Iceland’s volcanic highlands, an area historically used seasonally by farmers and later explored by geologists tracking geothermal activity.
Conservation
The highlands are fragile; stay on established paths to protect thermal ground and practice leave-no-trace. Operators limit group sizes to reduce erosion and disturbance.

Dress in layers
Weather changes rapidly in the highlands — pack a breathable base layer, insulating mid-layer and waterproof outer shell.
Sturdy footwear
Trails include loose scree, mud and wet boardwalks; hiking boots with ankle support and good tread are recommended.
Protect your camera gear
Steam and acidic minerals can damage equipment — use waterproof cases or plastic covers and clean gear after the trip.
Bring swimwear and towel
If you plan to use the Highland Baths, have a swimsuit and quick-dry towel ready — drying facilities may be basic.
Waterproof hardshell jacket
Keeps wind and driving rain off during exposed sections of the hike.
Hiking boots with good traction
Essential for rocky, muddy and scree-filled terrain common in the highlands.
Insulating mid-layer (fleece or down)
Temperatures can be cold even in summer, especially when wind is strong.
Daypack with water and snacks
Carry at least 1–2 liters of water, lunch and spare clothing for the long day.
