Raufarhólshellir Lava Tube

Raufarhólshellir Lava Tube is a prime example of Iceland’s volcanic caves. The cave formed when a lava flow from a volcanic eruption nearly 5,200 years ago gradually cooled on the outside. Underneath the crust, the liquid rock kept moving until it drained away thus forming tunnel below the surface.

It takes just a half-hour ride from Reykjavik to reach this hidden gem. Once we arrive, get prepared for an eerie adventure! We will walk through a moss-capped lava field and descend into a hole in the ground. When in the cave, vibrant colors and unique rock formations take your breath away. Stunning stalactite structures hang from the ceiling, and stalagmites rise from the floor of the cave. In winter, you even have a chance to spot icicles hanging together with other mind-bending formations.

The Blue Lagoon

After the caving activity, we will transfer you to the Blue Lagoon resort, the most popular attraction in Iceland. The thermal bath is famed for its milky blue waters and quirky history. It appeared quite unexpectedly when a geothermal power plant filled a lava field with run-off water that was unsuitable for heating systems. Since the water was hot and rich in minerals, it became a perfect place for a replenishing swim. The brilliant turquoise color is due to the silica and algae present in the water.

Today this iconic destination is famed for its curing properties. You will be able to have a luxury soak in hot water surrounded by the lunar-like landscape of the Reykjanes Peninsula. Just don’t miss out on the famous Blue Lagoon’s face mask of silica mud!


After the caving tour, we will stop for a lunch break at BSI Bus Terminal in Reykjavik. There is a cafeteria where you can try out some traditional Icelandic dishes or feel free to bring your own lunch.

How is it best to be ready for a pick-up for a tour with Arctic Adventures?

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.

Can I drink alcohol before or during Arctic Adventures tours?

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.

Do you offer any family friendly tours, for younger children?

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 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.

Can the itinerary for the tour change?

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.

Is there a guide on each Arctic Adventures tour?

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.

Can the guide advise if I am eligible for rescheduling the tour and/or a refund?

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

What type of power outlets are used in Iceland? Do I need to bring an adapter?

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.

How are the tours rated in terms of difficulty?

Our tours are split into four different categories that help participants to understand what to expect from the tour. The categories are Easy, Moderate, Challenging and Demanding. Each tour is rated making it easier to find tours that suit you.

For further information about the difficulty ratings and descriptions.


How does carbon offsetting work?

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.

What equipment do you provide for the lava tube caving trip?

We provide you with a headlight and a helmet.

What should I wear on a lava caving tour in Iceland?

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.
