Leirhnjukur Iceland (in the Krafla lava fields) – Visit Tips + Photos

The geothermal area of Leirhnjukur near lake Myvatn has been one of my favorite places to visit in Iceland. Even though I had just admired the colorful Hverir and the surprising Viti crater, I still managed to be blown away by the volcanic nature of Iceland. The particularity of this place? The lava field is still fuming!

Leirhnjukur & the Krafla Lava Fields

Leirhnjukur is a great example of why I love Iceland: this is a place where you can feel the power of Nature. Indeed, this geothermal area in North Iceland is partly composed of a lava field that is still steaming 30 years after the last volcanic event. As you will see in the photos below, this small hike was like landing on another planet.

Leirhnjukur is part of the Krafla Caldera and the Krafla Lava fields. 
The Caldera is 10km long and 2km deep.
In the last few centuries, two major periods of volcanic activity have occurred, the former in the Myvatn fires 1724-1729, and the latter in the Krafla fires 1975-1984.

Leirhnjúkur geology

What is called Leirhnjukur is an area of the Krafla caldera around a rhyolite formation (593 meter above sea level). The hill rises less than 50 meters above the surrounding lava field. The rhyolite of the hill is porous due to the geothermal heat and has in several places turned into clay, hence the name “clay hill”. 

Planning Tips - Leirhnjukur Iceland

Getting to Leirhnjukur

• North Iceland, close to Lake Myvatn
• From Myvatn, drive East on Road 1 for 6 km. Then turn left towards Viti/ Krafla and drive past the power plant
• The various features of the area are not well indicated. You will see other carparks. After driving past the power plant, the first parking on your left is the one for the Leirhnjukur trail.

Leirhnjukur (with its GPS coordinates) is included in my eBook to help you easily plan your road trip:

Visiting Leirhnjukur - Trail map

• Small loop (1h) -the first half of small loop is a board walk which was actually the slippery part
• Big loop (2h taking my time, 5km) – Nothing steep but wear good shoes
• DO NOT go off-path unless you want to melt your shoes.
• Amenities: toilets at the parking
• Be careful in the lava, some trail markers disappear in the snow in Winter. Watch Leirhnjukur covered in snow on the 91 days in Iceland website

Staying close by

There is a good offer of accommodations around Lake Myvatn.
I chose the Dimmuborgir guesthouse on the shore of the lake and had a great time - Check out photos and book

Walk from the parking of the Leirhnjukur Lava Fields

Just 100m from the parking, you get in the mood: you enter amazing scenery that looks post-apocalyptic with interesting colors. No need to push me to continue walking further. The bar is set.

The pools at Leirhnjukur mountain

One of the first features on the small loop is the pools. The boardwalk goes 3/4 around it. As often in a geothermal area, the colors are fascinating, I especially liked the view with Viti and Krafla in the background.

The fuming lava field of Leirhnjukur

As I wrote earlier, my favorite part was walking in the lava that was still fuming. It was an incredible experience and I took all my time walking the loop discovering interesting rock formations. On this part there are no boardwalks. Little poles indicate the path to follow to avoid melting the sole of your shoes 🙂

Other geological features of the Leihrnjukur hiking trail

Part of the small loop goes across the rhyolite hill where you can see strange colors: some features are very white, others red, many dark and grass still manages to strive!

Along the way I found many fissures. I love photographing them. I think this one looks very impressive.

Surreal landscape

This was taken on my way back. The lava has created here some soft shapes. In the background are Viti and Krafla.
