Torfajökull Volcano
In 1477, Iceland saw its largest rhyolite eruption in over a millennium. It came from the Torfajökull (pronounced “Toor-va-yo-kytl) volcano.
A Story Written in Fire
North of Mýrdalsjökull glacier, Torfajökull rests in a remote area of South Iceland. Over a thousand years ago, Icelandic settlers passed through steaming valleys and multicolored mountains here. They called the area "Torfi's Glacier," after a man named Torfi Jónsson who, according to legend, may have hidden there during a plague.
This might be a legend, but the volcano is real and very much alive. One of the most active geothermal zones in Iceland today is inside the area including the famous Landmannalaugar.

What Is Torfajökull?
Torfajökull is a glacier located in the centre of a large volcanic system, the Torfajökull Volcano. It includes a huge caldera, lava flows, geothermal areas, and hot springs.
The volcano lies in a rift zone where tectonic plates pull apart. This allows magma to rise close to the surface.
The caldera is about 18 km (11 miles) wide. It was formed by past eruptions and the collapse of the volcano's center. Although sometimes described as a crater, the feature is actually a type of sinkhole as it is formed through subsidence or collapse rather than an explosion or impact.

Eruptions That Changed Iceland
Around the year 870, a powerful eruption from Torfajökull blanketed the entire island in ash. This layer became a vital reference point, helping archaeologists date many artifacts from Iceland’s early settlement period.
The eruption in 1477 was another major event. It was part of a rare mixed eruption involving both basalt and rhyolite magma. This means that two different magma chambers were involved. The eruption spread ash and lava across a large area.

A Geothermal Wonderland
Torfajökull is rich in geothermal activity. High-temperature areas produce steam vents, bubbling mud pools, and sulfur deposits.
It is easy to spot from a distance because of its colorful rhyolite mountains. These colors - red, yellow, green, blue, and pink hues - come from chemical changes caused by heat and water.
Hot springs are scattered throughout the region. Some are safe to bathe in, while others are too hot.
A Living Landscape In Motion
Torfajökull gives scientists a view into Iceland’s volcanic system. The presence of two magma chambers is rare. It shows how complex volcanic systems can be.
It’s also a reminder of how the land continues to change. The area is shaped by both ancient and recent volcanic events.
Visiting Torfajökull
Torfajökull is one of those places that feels like another planet. It’s way out in the highlands of South Iceland, and you can only get there in summer, with a 4x4 vehicle. There are no towns or shops, and barely any cell signal. Just you and the wild.
If you go, you’ll need to bring everything: food, water, warm clothes, and a good map. But the trip is worth it. As you drive in, the landscape changes. Black lava stretches for miles. Steam rises from the ground. Lava flows and geothermal steam mark the landscape.
You are walking through a place shaped by ancient eruptions and deep heat below the surface. It’s quiet, raw, and completely unforgettable.
Tips for Visitors
- Only travel in summer
- Use a 4x4 vehicle
- Check weather and road conditions
- Stay on marked trails
- Do not bathe in unknown hot springs

Hiking in the Area
This region is a favorite for hikers, particularly the Landmannalaugar area on Torfajökull’s northern edge, known for its scenic trails, colorful landscapes, and geothermal bathing spots.
Popular hikes include:
- Landmannalaugar to Hrafntinnusker trail
- Brennisteinsalda hiking trail
- Around the caldera rim.
The trails take you through lava fields, steaming valleys, and vibrant hills.
