Fun for the whole family!

On this tour, we will go to Iceland’s largest natural lava cave that is located in West Iceland. We will drive from Reykjavík through the beautiful Borgarfjörður towards Húsafell. On the way we will stop at the most powerful hot spring in Europe, Deildartunguhver and the magnificent Hraunfossar lava waterfalls.

After a break in Húsafell, we head to the stunning Víðgelmir cave (148000 m3) which is one of the largest natural lava caves in the world. There we start an adventurous and guided walk down the great, colourful and beautiful lava cave. We will learn about its history and geological uniqueness which dates all the way back to the Viking age.

Following the cave adventure, we relax at the geothermal pool at Húsafell and then we drive straight back to Reykjavík.

    Vidgelmir Lava Caves

    5.0 stars on  Monday, August 28 2017

    We had a great tour of the Lava Caves. The thermal pool was a waste of time but we found a new hotel adjacent with a bar and very pleasant staff. A bonus was the return trip to Reykjavik off the beaten path were the scenery was even more spectacular than visible or imaginable from the main road... more

This hot spring is the highest-flow hot spring in Europe. The water is about 97°C when it emerges and is some of the water used for heating in the towns of Borgarnes and Akranes.



The waterfall is made from a series of rivulets streaming underneath Hallmundarhraun lava. Hallmundarhraun flowed from an eruption from a volcano underneath Langjökull glacier in the 9th century.



Húsafell is a lush green area with summer cabins, camping area, a hotel, a swimming pool and more. It is very popular with Icelanders during the summer months.



The cave is the largest lava cave in Iceland, situated in Hallmundarhraun lava. It is also one of the largest lava caves in Europe.
