Lava Cave & Geothermal Adventure

Lava Cave & Geothermal Adventure
Cold water springs run through the lava rock at Hraunfossar, spiraling out into many miniature waterfalls.
Hraunfossar ('Lava Waterfall') is a rare example of natural phenomenon rarely seen in Icelandic waterfall.
A 'lava tube' is where a hot lava river once flowed underground, and where the cooler rock around it hardens, thus leaving a hollowed out tube.

Sign up for this one of a kind geothermal adventure, exploring the depths of Iceland’s largest natural lava cave, Víðgelmir!

Once you have been picked up from your hotel in Reykjavík, you will be driven through the beautiful Borgarfjörður region toward the sprawling farm and church estate of Húsafell.

Borgarfjörður is an area of untouched wilderness, an epic landscape of waterfalls, mountains and open sky. As you travel through the region, you will be truly awe-inspired by the breadth of natural beauty around you. Make sure not to forget your camera!

On your way to the lava cave, you will stop off at the most powerful hot spring in Europe, Deildartunguhver. Here, a very high flow rate pushed water from the spring at a scorching 97° C! This is a unique geothermal spot and you will be amazed by the active vents pouring huge steam clouds into the sky.

You will also stop at the Hraunfossar lava waterfalls, a rare natural phenomenon. This series of falls comes directly from the rivers within Hallmundarhraun, an area consisting of dried lava that originated from one of the volcanoes beneath the incredible Langjökull glacier. The falls are an amazing sight to behold, and your guide will be quick to inform you that the water cascading here originally came from cool underground springs.

After a short break at Húsafell, you will head to your main destination, Víðgelmir lava cave. The cave is 148,000 square metres and is famous for eerie, subterranean beauty. Deep inside, you will find lava stalagmites and stalactites, intricate ice formations and multi-coloured rock faces.

Specialists believe that this lava cave is one of the most geologically remarkable caves on earth. Following your trip inside the cave, you will take some time relaxing at the Húsafell geothermal pools before heading back toward Reykjavík.

So don’t delay! Book today to reserve your place on this intriguing geothermal expedition, exploring Europe’s largest lava cave, and many fascinating spots along the way! Check availability by choosing a date.
