Lost in the heart of Iceland, Kerlingarfjöll, literally: “the mountains of the good woman”, is a very active geothermal site.
It is a remote mountain range in central Iceland that offers unforgettable hikes.
The highest point in this mountain range is Mount Snaekollur (1488 m). Kerlingarfjöll is part of the rift zone in the Atlantic Ridge that crosses Iceland from south-east to north-west and belongs to a volcanic network that stretches 100 km².

Kerlingarfjöll: one of the most beautiful sites in Iceland
Kerlingarfjöll and its contrasts, near the second car park
The particularity of Kerlingarfjöll is the orange color of its flanks, which comes from the rhyolitic stone that makes up the vast majority of this mountain.
Not being located along Road number 1, you won't find that many tourists in Kerlingarfjoll, yet it is one of the two or three most beautiful sites in the country. Any visitor who goes to Kerlingarfjöll is struck by the chromatic harmony, almost a painted composition with the flame-coloured mountains contrasted by the snow, especially on a clear day.
Like the Landmannalaugar region, the Kerlingarfjöll region is renowned for its incredible landscapes and panoramas and is a must for all hiking enthusiasts.
How to get to Kerlingarfjöll?
Though it is possible to reach Kerlingarfjöll via the F347 east and the F26, the easiest and most convenient way to get there is to get there from the south or from the north via the Kjölur trail: number 35. Generally, after spending the night near the Golden Circle, visitors leave the next morning to visit the Kerlingarfjöll Mountains, as the Golden Circle connects to off-road trail 35.
4x4 journey via Trail 35, then F347
Starting from Gullfoss, take the Kjölur red stone road for about an hour until the next junction, driving past the beautiful Hvitarvatn lake. It's a bumpy ride, very much so in fact, with deserted landscapes that bring to mind the red planet Mars.
From the crossroads mentioned above you have two options: continue straight on the 35 towards Blonduos via the oasis of Hveravellir for about 30 km from here, or branch off onto the F347. The F347 track is now in much better condition than it used to be but beware: a few unbridged stream crossings may remain (usually shallow, but check the weather and the condition of the track on umferdin.is). After a short quarter of an hour on the trail (10 km), you will see Gýgjarfoss, a small waterfall that is worth at least a quick stop.
A few kilometers away, you'll find the first car park for the Kerlingarfjöll site, complete with chalets and a sign leading to Asgarðsfjall.
In the end, the track that leads to Kerlingarfjöll is quite easy and although you'll need a 4x4 vehicle (for the off-road trail F347), it's not a particularly challenging drive.
By bus
The site is also accessible by bus. Note that there is no longer a regular bus service on the Kjölur (the former SBA line 610 between Reykjavík and Akureyri no longer runs). In summer, however, the site operator, Highland Base, runs bus shuttles from Reykjavík (8:30) and Gullfoss (10:30), returning from Kerlingarfjöll at 17:00, daily in July and August (16,500 ISK one way). Dates and times should be checked on highlandbase.is.
For additional information, consult the website http://www.publictransport.is/ or our article on buses in Iceland.
Guided tours
The superb reliefs of Kerlingarfjöll
It is possible to visit Kerlingarfjöll on a day tour from Reykjavík, with a bus transfer, a guided visit of the Hveradalir valley, access to the hot springs and stops at Gullfoss and Geysir (daily in July-August, on selected days in June and September).
Where to park?
In fact, there are two parking lots in Kerlingarfjöll where you can park and strike out on foot for the hiking trail. Look for the green and red huts easily recognized from afar which point you to the main car park, the location named Neðri-Hveradalir.
The second car park is slightly higher up the trail. Pass the huts for about 4.5 km on the bumpy track to the small car park at the Kastali hut.
The choice of parking depends on your hiking skills and what you plan to do (see below). Neðri-Hveradalir is the main car park from which the majority of hikers leave.
Kerlingarfjöll hikes
As soon as you arrive on site, you'll realize the place is big, in fact immense and worth every drop of sweat as it is truly magnificent, the color contrasts simply magical. The flaming orange-yellow rhyolite hills contrast with the bright green grass and white streaks of snow, add to that the fumaroles and solfatars, with all around you the pungent smell of sulfur, and you have one of the most magical places in Iceland.
Perhaps the most impressive thing is when you get a sense of scale seeing the size of the hikers in the distance compared to the majestic mountains. If you have the chance to visit with good weather, the sunlight hitting the orange flanks is a spectacle unlike any other.
Hikes everywhere
Kerlingarfjöll hiking map
There are so many hiking trails in Kerlingarfjöll, almost twenty. Some will take you on a complete ascent of the Fannborg and Snaekollur mountains, with a splendid view of all of Central Iceland from the peak.
The map of possible hiking trails is posted in the image above. Depending on the car park you choose (Neðri-Hveradalir or the Kastali hut), the site offers enough hiking options for every taste.
You are sure to find exactly what you want, from a 1-hour leisurely hike to a full 3-day marathon! All official hikes are listed on the official website http://www.kerlingarfjoll.is.
The Hveradalir hike
The best known hike in Kerlingarfjöll is without a doubt the Hveradalir trail and we highly recommend it. This hike is detailed in our dedicated article about this hike. Its 6.5 km will take you at least 2 hours to reach the Hveradalir site (one way only) with a significant elevation factor. This hike starts from the main car park in Neðri-Hveradalir and offers absolutely breathtaking landscapes!
The Austurfjöll hike
This walk starts from the Kastali hut, the second parking lot, and takes you to the steep slopes of Lodmundur and Fannborg. The ascent continues until you reach the summit of Snaekollur at 1488 m. The walk is 7 km long, and you have to count 5h30 to complete the whole loop.
Swim in a hot spring!
As promised, this is your reward for all the effort. Kerlingarfjöll is an important geothermal area, and this often means hot springs nearby.
Very close to the campsite, hike up the Hveradalir for less than 1 km to find a gorgeous stone pond.
In the Asgarður valley, the operator of the site has built the “Highland Baths”: a hot pool, a cold bath and a sauna, with views over the mountains. They are open to everyone from 15 June to 30 September (around ISK 5,500 per adult, booking recommended, access included for hotel and chalet guests). Check highlandbase.is before you go, as the old small natural pools are no longer signposted by the site.
When to go there?
Neðri-Hveradalir huts in Kerlingarfjöll
Summer between mid-June and early September is the ideal period.
As strange as it may seem, the site is open all year round in winter and summer for the hotel and the chalets, but the campsite, the A-frame huts and the dormitory are only open in summer. Although it is clearly in summer that the contrasts and colors of the place exude the most magic, some visitors go there outside of summer for a bit of peace and quiet.
However, you should know that in winter, the tracks are not cleared of snow and the site can only be reached by 4x4 super jeep with a professional driver (transfer to be booked in advance), and generally, from October to May, the region is covered in snow.
Sleep in Kerlingarfjöll
The first parking lot and the huts of Neðri-Hveradalir in Kerlingarfjöll
Neðri-Hveradalir, with the red and green huts mentioned previously, is next to the Kerlingarfjöll Mountains camp site, which has its official website http://www.kerlingarfjoll.is. It is the only place to sleep in the entire region.
The place is very well-equipped and has a restaurant that serves breakfast, as well as a building with an equipped kitchen.
Recently, the site has expanded to include a new building with no less than 20 double rooms with very modern private bathrooms. In addition, there are also 10 small independent chalets, and another chalet where you can lay out your sleeping bag for a budget option.
Very close to the huts, you can even pitch your tent on a large camping ground. A former ski resort dating back to 1991, only the chalets remain open today.
The place is very popular, obviously since it is the only place to sleep for miles in every direction, so you'll need to book as early as humanly possible.
Our opinion
Kerlingarfjöll color palettes
The Kerlingarfjöll site is most definitely remote, requiring quite the expedition to get there, but it is really a little slice of paradise that offers absolutely incredible views you won't see anywhere else.
There are so many absolutely stunning hiking trails that it would be a shame not to go there. Being located along Route 35, it is also a convenient mid-point on any journey from the south to the north, such as visitors leaving the Golden Circle to go to Lake Myvatn or Akureyri.
