Private Kerlingarfjoll Highlands Adventure: Day Tour to Iceland’s Geothermal Witch Mountains
A private day tour to Kerlingarfjöll turns an 8–9 hour itinerary into an immersion in Iceland’s geothermal highlands: rhyolite ridges, steaming vents, and snow-scoured valleys. This guide covers what to expect on the trail, the geology underfoot, and practical tips to prepare for rapidly changing weather.
The Experience
Before You Go
Layer for variable weather
Temperatures and wind change quickly—pack a breathable insulating layer and a waterproof shell.
Wear sturdy, waterproof boots
Trails are uneven and often wet or muddy; ankle support and good soles improve comfort and safety.
Respect geothermal features
Stay on marked paths and observation areas—ground can be fragile and dangerously hot near vents.
Bring snacks and water
Long driving times and limited services in the highlands mean self-sufficiency on the trail is useful.
Local Knowledge
Hidden Gems
- •Hveradalir valley viewpoints just above the geothermal vents for low-crowd panoramas
- •The thermal pools at the highland hotel— quieter early in the afternoon after day-trippers leave
Wildlife
- •Arctic fox (rarely seen)
- •Ptarmigan and highland waders
Conservation Note
The highlands are ecologically fragile—stick to marked trails, avoid introducing non-native plants on boots, and pack out all waste to protect geothermal habitats.
The Kjölur highland route nearby has been used for centuries to cross Iceland; Kerlingarfjöll itself was long avoided except by shepherds and highland travelers due to harsh conditions.
Photographer's Notes
- • Ridge above Hveradalir for panoramic shots of rhyolite colors
- • Edge of the main geothermal valley to capture steam plumes against snow

Common Questions
How long is the tour from Reykjavík?
The full excursion runs about 8–9 hours, including roughly five hours of driving round-trip between Reykjavík and Kerlingarfjöll.
Is the hike strenuous?
No—the hike in Hveradalir is short (around 2–4 km round-trip) with modest elevation gain, but the terrain can be uneven and muddy.
Can I use a regular rental car?
No—highland roads are rough and some are F-roads; tours use appropriate vehicles and private transfers are included on this trip.
Are there changing facilities or baths?
There’s a highland hotel on site where you can stop for lunch and, seasonally, swim in thermal baths—bring a swimsuit and towel if you plan to go in.
Is the area safe around steam vents?
Only when you stay on marked trails; crust around hot springs can be thin and dangerously hot—follow your guide’s instructions.
Do I need to bring cash?
Most tour payments are handled in advance; bring a small amount of cash or card if you plan to buy refreshments at the highland hotel.
