Kerlingarfjöll Mountain Range In a Nutshell
Kerlingarfjöll is a relatively young mountain range formed about 10,000 years ago by Iceland's volcanic activity. Covering roughly 100 square kilometers (39 square miles), it's part of the Tuya volcano system and reaches a height of 1,477 meters (4,846 feet).
Known for its vibrant rhyolite mountains, Kerlingarfjöll displays colors that shift with the sunlight, creating a stunning visual effect throughout the day. A highlight here is the Hveradalir geothermal valley, home to Iceland's third-largest geothermal area. Visitors can see geysers, steam vents, bubbling clay pits, and the iconic Kerlingarfjoll hot springs.
This surreal landscape is a striking mix of steam clouds rising against glacier-capped mountains, with a few small ice caps nestled under the shadow of the massive Hofsjökull glacier. Since 2017, the 367 square-kilometer (141 square-mile) Kerlingarfjöll area has been a protected nature reserve, offering an off-the-beaten-path experience similar to Landmannalaugar.
How to Get to Kerlingarfjöll in Iceland
To reach Kerlingarfjöll in Iceland from Reykjavik, plan for a scenic drive of approximately 200 km (124 miles), which takes around 3-4 hours. Start from the iconic Gullfoss waterfall and head north along the F35, known as the Kjölur Road.
Historically, this route served as a vital horse trail and trading path through Iceland's interior. The journey begins with about 15 km (9 miles) of asphalt, then shifts to a 38 km (24 miles) gravel road.
For access to the mountain base and the Hveradalir geothermal area, continue on the F347 road. The F347 winds through highland landscapes, leading directly into Kerlingarfjöll.
Driving Advice
- Vehicle Requirements: A 4x4 is essential for navigating these F-roads (Highland Roads), as standard vehicles are not equipped to handle the challenging conditions, which include potholes and uneven surfaces. Attempting to drive a smaller car can lead to damage or getting stuck.
- Road Conditions: These roads are typically open from late June to September, but conditions can vary greatly due to weather. Always check the weather and current road conditions at the Icelandic Road and Coastal Administration website before your trip.
- Fuel: Ensure your vehicle has a full tank before setting out, as gas stations are scarce in this remote area.

Hveradalir Hike
- Distance: 11 km / 7 mi (return)
- Hiking Time: 5-6 hours
- Difficulty: Challenging
The Hveradalir hiking trail begins at the car park, where hikers cross a small footbridge over a stream. Look for a large red sign marking directions to Hveradalir (straight) and the Kerlingarfjöll hotpot (left). The well-marked trail makes navigation easy in clear weather.

The trail then descends and ascends two small slopes, crossing snowy névé fields, and reveals landscapes that shift from rocky to ocher-colored slopes, rich in rhyolite minerals. The contrasting ochre, snow, and green moss create stunning scenery.
As you approach the summit, sulfur fumes and the unmistakable smell of geothermal activity fill the air, visible from a plateau 1.1 km (0.7 mi) away. Enjoy 360° views of active fumaroles and vibrant rock colors. The return is a downhill path, taking about 1 hour and 40 minutes to complete.
Snækollur Summit

The Snækollur Summit hike begins at the Hveradalir geothermal area car park and follows a straightforward out-and-back trail, making it the easiest option for navigation. The main route first leads hikers to Fannborg Peak before continuing on to Snækollur.
While there are several alternative paths to Snækollur, many are unmarked, adding to the challenge and making it easy to lose your way.

The striking colors in the landscape come from sulfur and salt deposits, making this an unforgettable way to explore Hveradalir's geothermal wonders.
Mænir Peak

The journey back to Ásgarður covers the final 17 kilometers (11 mi), bringing the adventure full circle. Despite its reliance on remote and challenging conditions, such as snow and high altitudes, this trail provides a less crowded alternative to the popular Laugavegur route for those seeking solitude and a deeper connection with Iceland's rugged terrain.
