Beyond Iceland’s Golden Circle: A 6-Day Kerlingarfjöll Highlands Itinerary

Iceland is not short on geothermal landscapes. The problem is that most first-time itineraries funnel everyone toward the same roadside waterfalls, geysers and parking lots.
Kerlingarfjöll is the antidote: a highland mountain range of rust-colored ridges, steaming valleys, snowfields and trails where the weather still dictates the day. The destination is also part of a broader 2026 travel shift toward more physical, restorative trips—what some current travel coverage is calling “sweat-jetting”: travel built around movement first, spa recovery second.
In Kerlingarfjöll, the hot bath feels better because you earned it on the trail.
The combination works. Hike through geothermal terrain in Hveradalir, climb toward Snækollur, ride an e-bike across the highlands, then finish the day in Highland Baths with a sauna and cold plunge. It is Icelandic wellness without pretending the landscape is merely a backdrop.
Beyond Iceland’s Golden Circle: Why Kerlingarfjöll Is Having a Moment
Highland Base has turned a once-rustic mountain outpost into a comfortable base for hikers while keeping the geography front and center. At the same time, events such as the sold-out 2026 Kerlingarfjöll Ultra have introduced a wider active-travel audience to the region.
This is still not the easy Iceland. Access depends on highland road conditions, weather can shift quickly, and a 4×4 is the sensible default for self-drivers when the roads are open. That friction is part of what protects the experience.
The 6-Day Itinerary
Day 1 — Reykjavík, But Keep It Short
Arrive in Reykjavík, recover from the flight and use the evening for an early dinner. The point is not to build another capital-city itinerary; it is to be rested for the highlands.
Dorian pick: Stay somewhere that makes a fast morning departure easy. One good dinner and a full night’s sleep beats squeezing in every city landmark.
Day 2 — Into the Highlands
Pick up a suitable 4×4 and drive toward Kerlingarfjöll when seasonal roads are open, or book a private highland transfer if you do not want to manage F-road conditions yourself. Arrive at Highland Base, check in and take a short orientation walk rather than attempting a major hike immediately.
Finish with the Highland Baths. In the main summer season, the baths are open to both guests and day visitors, with sauna and cold-plunge elements built into the experience.
Day 3 — Hveradalir Geothermal Valley
Make Hveradalir the first serious hiking day. The valley is close enough to Highland Base to be approachable but dramatic enough to deliver the full Kerlingarfjöll effect: steaming vents, mineral-colored slopes and trails threading between active geothermal features.
Dorian pick: Start early, carry waterproof layers even when the morning looks clear and stay strictly on marked routes around geothermal ground.
Day 4 — Snækollur Summit Day
For fit travelers, use the clearest forecast day for Snækollur. Route references commonly estimate roughly four hours return from the Highland Base area, depending on conditions and chosen approach. The payoff is broad highland views that make the region’s isolation tangible.
If wind or visibility is poor, do not force the summit. Swap in a lower route and save the mountain for another day.
Day 5 — E-Bike, Recovery & Long Bath
After two hiking days, change the movement pattern. Highland Base offers seasonal e-bike activities, and the broader area is well suited to a guided ride that lets you cover more ground without turning the day into another summit push.
Return for a long soak, sauna and early dinner. This is the day the “sweat-jetting” idea actually makes sense: exertion followed by deliberate recovery, not a wellness treatment squeezed between sightseeing stops.
Day 6 — Return via the Interior
Leave Kerlingarfjöll after breakfast and return toward Reykjavík. If conditions and timing are good, add one carefully selected stop from Iceland’s Golden Circle on the way back rather than trying to do the entire circuit.
Dorian pick: Stay near the airport or Reykjavík for one final night if your international departure is early. Highland road weather and flight connections should not be stacked tightly together.
Standout Excursions
Hveradalir: The essential hike. Even travelers who skip a summit day should make time for the geothermal valley.
Snækollur: The best option for hikers who want the trip to feel genuinely alpine rather than simply scenic.
Highland Baths: Not an add-on. The contrast between cold, wind, hiking and hot water is central to the experience.
Guided e-bike: A smart way to add range without repeating the same type of physical effort every day.
Best Time to Go
The practical self-drive highland season is usually concentrated between roughly mid-June and mid-September, but road openings and closures are controlled by conditions, not a fixed calendar. Highland Baths currently lists a broader summer operating period through September 30. For a 2026 trip in early September, confirm road status before departure; for 2027 planning, do not book a tight nonrefundable driving schedule until seasonal access is clear. Unlike Iceland’s Golden Circle, which is drivable in nearly any weather, this itinerary depends entirely on the highland road being open.
Who This Trip Is For
Active couples, small groups and repeat Iceland travelers will get the most from it. You should enjoy walking in exposed weather, be comfortable with plans changing and value landscape over nightlife — in short, travelers ready to go beyond Iceland’s Golden Circle rather than repeat it.
Booking & Logistics
Reserve Highland Base well ahead for peak summer. Self-drivers should use a vehicle permitted for highland/F-road travel and check road and weather conditions daily. Travelers who do not want that responsibility should arrange a private highland transfer or guided super-jeep access.
Pack waterproof shell layers, gloves, a warm hat and proper hiking footwear even in summer. Kerlingarfjöll is not difficult because it is technically extreme; it is difficult because highland weather can change faster than casual travelers expect.

Dorian Destinations Verdict
Kerlingarfjöll is the Iceland trip we would build for someone who has already seen the obvious—or for a first-timer who cares more about being in the landscape than checking boxes.
Give the highlands several nights. Let weather dictate the summit day. Hike hard enough that the baths feel necessary. That is a much better story than another rushed lap around Iceland’s Golden Circle.
