Iceland is known for its volcanic activity across the country. This is your chance to explore the fascinating subterranean landscape beneath the lava fields. 

Raufarhólshellir is one of the longest and best-known lava tubes in Iceland. This is a great opportunity to see the path of an ancient volcanic eruption. The Leitahraun eruption carved out the landscape around 5200 years ago. Every winter, wondrous icicles appear at the mouth of the cave. 

The tunnel stretches about 4500 ft (1360 m), 30 m wide with headroom up to 10 m high.

Really nice guide

We (my boyfriend and I) did the Underworld tour. The guide was very friendly. I also ended up facebook messaging the actual company, and they were pretty responsive (~30 mins to an hour). The only thing I had trouble with was the directions on where to go to meet on site. The tour itself was a lot of fun. You were crawling/walking over rocks at some parts though.

Meet on location means travelling to the location of the tour yourself and then meeting our tour guides rather than being picked up and taken to the location.

This is a great question. We ask all participants to be ready from the start of the pickup time indicated. This is because you may well be the first pick up of the day. Please be at your assigned location at the start time that you chose when booking the tour.

Here you should wait for your guide.

Have your email and phone number listed with us so we can contact you if we run into any trouble finding you.

Before and during activities on the multi-day tours consumption of alcohol is prohibited. If we suspect that a participant is intoxicated, we will prohibit them from joining the activity.

After the activities of the day are finished, you are welcome to have a drink and relax.

Yes, we do. Langjökull Ice Cave is a magical experience, the tour has no minimum age and is a wonderful option for the whole family. Whale Watching with our partner company Elding has been a favourite with families traveling with young children, these guys have a great success rate in seeing whales (upwards of 98% in the summertime).

Another option would be the Landmannalaugar Safari on this tour you get to explore parts of the Icelandic highlands and bathe in natural hot springs. Most of our super jeep tours are also suitable for children over the age of 6 years old. If you would like a nice and relaxing experience we would also recommend the Golden Circle & Secret Lagoon tour.

Your safety is our number one priority! Keeping this in mind, Arctic Adventures reserves the right to adjust the itinerary and/or take different routes depending on conditions. Please read more information in our cancellation policy.

Yes, there is a specially trained and certified guide on each of our tours. The only exception to this is for our self-drive tours.

All of our tours are guided in English.

No, for all your questions and concerns you would need to contact our customer service.

The standard in Iceland is 230V and 50Hz and we use F-type power sockets and plugs, so you might have to bring an adaptor if you are visiting from UK, USA, Canada or other countries using a different voltage, Hz or plugs.

We’ve partnered with the Kolviður Fund in a new carbon offsetting program, which passengers can select to participate in at the time of booking.

The Kolviður Fund is the oldest, most respected carbon offsetting program in Iceland. With your support, one tree will be planted in special Kolviður forests in Iceland to carbon offset your tour with us.

Kolviður forests are strategically planted to absorb the maximum amount of CO2 and the forests are protected for a minimum of 60 years. During their lifetime the trees absorb carbon and store it in their root system, trunk, and branches. Trees also prevent soil erosion and maintain storage of carbon in the soil.

We provide you with a headlight and a helmet.

Like always in Iceland, it’s best to dress in layers. Warm layers closest to you preferably wool/thermal underwear, pants sweater and on top waterproof outdoor clothing. We also recommend that you wear good hiking boots and gloves. Jeans have proven to be a bad choice.

Peak experience underground!

This lava tube cave tour was fascinating and quite different from the limestone caves we've visited in other countries. Our guide was punctual, friendly, informative, and attentive to the needs/concerns of the various members of our tour group. Highly recommended!

Amazing Experience

Going through the lava tube was one of the most exciting and scariest things I've ever tried. Having to squeeze through some of the tight spaces was something I never expected, but absolutely my favourite part. The tour guide was knowledgeable and very friendly.

The lava cave tour was great! Pedro was a fantastic guide, and was able to assist me through the more challenging areas since I have hip replacements & very bad knees. I love that the cave is kept natural. It's fascinating to learn how the cave was created, and see what's been left behind. Sitting in total darkness was relaxing. I like that it was just challenging enough to feel.a bit adventurous. I would definitely recommend this excursion.
