The dormant Þríhnúkagígur volcano is a unique natural phenomenon. By setting up the necessary gear and equipment, we’ve created a tour that opens the door to a new world.
Enter Þríhnúkagígur volcano and descend into the only accessible lava chamber on planet Earth. What awaits you down there is truly magnificent.

To be able to experience this wonder, all you need is the willingness to do a moderate 45–50 minute hike (to get to the crater) and the guts to descend 120 meters/400 feet to the bottom of the crater in an open cable lift. The hike to the volcano is an integral part of the tour, not only because of the breathtaking scenery, but also because it’s one of only two ways of getting to the base of the volcano. The other option is to use a helicopter.

The name!
The volcano’s name Þríhnúkagígur, mostly unpronounceable for anyone other than locals, would be directly translated as ‘Three Peaks Crater’.

The only accessible lava chamber on Earth
Þríhnúkar is a safely dormant volcano that has erupted three times. The last eruption, which took place about 4,500 years ago, left behind a unique natural phenomena: Þríhnúkagígur. It is truly one of a kind and the only accessible lava chamber on Earth. Inside, the beautiful coloration and unique rock formations represent all the shades and shapes of the earth where its size is enormous and to some extent intimidating.

What’s included?

  • All safety gear, helmets, harnesses, etc.
  • Small groups, plenty of guides = personal experience
  • Volcano tour of a lifetime
  • Traditional Icelandic meat soup, coffee/tea and perhaps some sweets as well. We also serve vegetarian soup.

Difficulty level:
Moderate fitness level required (see more below)




Please note

  • We operate form May 5th to October 31st every year
  • The tour takes about 5-6 hours including pick-up


5–6 hours (about 40 minutes are spent inside the volcano).

Fitness level needed:

Moderate (the level of difficulty is 2 out of 5). No knowledge of hiking or climbing is required. It’s not a steep uphill walk, but the surface is uneven in places. The last 10 minutes of the hike are the more challenging, with an elevation of around 50 m/150 ft. This is NOT a tour for those in limited physical shape.

Distance walked:

Approximately 3.5 km (2 miles) each way. The walk usually takes around 45–50 minutes (depending on the condition of people in the group). A guide will be with you at all times during the walk.

Minimum age limit:

8 years old, but we do make exceptions. Children that are able to hike 2 times 3.5 kilometers, even in bad weather, are welcome to join the tour. If this applies to your child and you have appropriate clothing, then you can go ahead and book your ticket on the booking site. Note that we cannot make a refund if it turns out that your child is not able to finish the hike. Also note that we do not recommend that people bring infants into the crater.

What do I need to bring?

  • Good shoes – We recommend wearing hiking boots on the tour since the trail is rocky and can get wet and muddy on a rainy day.
  • Outdoor clothing. The weather in the mountains can be very different from the conditions in the city. It’s important for guests to realize that the weather is very unpredictable, and you should definitely bring warm, rainproof clothes with you, even if the weather in Reykjavík is nice and the forecast looks good. Not least because it’s always the same temperature inside the crater – about 3°C (37°F). That’s cold!
  • A camera. You will want to remember this trip. Yes, you can take as many pictures as you want!
  • A good spirit. This tour is all about having fun.
