This tour offers multiple departures a day from Reykjavík where you will be picked up from your Reykjavík hotel.

We enter through the top crater and descend to the bottom of its magma chamber, which was once filled with steaming hot lava. Thrihnukagigur Volcano is the only spot on earth where it’s advisable to explore a magma chamber from the inside. The volcano has not erupted for 4.000 years and shows no signs of coming to life anytime soon, so it is safe to enter.

The volcano is located approximately 25 minutes from Reykjavik. Once we arrive, we will need to hike across a lava field in order to reach the crater the surface can be hilly and uneven. The walk is moderate and usually takes around 45-50 minutes (3km / 2miles each way).

When we have reached the crater you will be lowered 120 meters (400 feet) in an open elevator for about 6 minutes. All equipment and procedures have been tested extensively and approved by the administration of Occupational Safety and Health in Iceland.
Everyone that goes down into the crater will have a harness and required to use a helmet at all times. All guides are experienced mountain guides and cave explorers and will be with you at all times. You will spend approximately 40 minutes inside the volcano.
Groups are small, so you will have the personal attention of your experienced guides.

What to bring: Good & sturdy hiking shoes are important, warm outdoor clothing as the temperature inside the crater is always the same 5-6°C / 42-43°F.

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

This is a great question. We would like to ask all participants to be ready from the start of the pick-up time as you could be our first pick up.
Please be at your assigned pick-up location from the start time of your pick-up and wait for your guide to arrive.

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?

No, absolutely not. Due to safety reasons, it is strictly prohibited. If we suspect that participants are intoxicated we will prohibit them from joining the tour.

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 favorite with families traveling with young children, these guys have a great success rate in seeing whales (upwards of 98% in the summer time). 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 (the hot spring part is particularly popular with the kids:)). 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.

Do I need an insurance before going on an Arctic Adventures trip?

We recommend that you have personal health insurance coverage when participating in any adventure activities in Iceland, we actually recommend that whenever and whereever you travel you take out a good travel insurance, as world travelers ourselves it has saved us money and aggravation many times.

What is a safety briefing?

Before starting any of our more technical trips, participants will receive a safety briefing highlighting the safe and proper use of equipment, the role of guides during the trip, and the significant risks and hazards involved in their particular trip. The safety briefing will also cover potentially foreseeable scenarios that may arise and explain how participants should react in such circumstances. Our guides will also outline their expectations of participants during the trip where needed and address any specific questions or concerns that may arise during this time.

Any medical conditions or personal health concerns that may jeopardize your well-being or affect your ability to meet the physical demands of the trip must be clearly communicated to the trip leader before the tour start. Any medications you may require for minor medical conditions (asthma inhalers, etc.), should be kept close and you should bring it with you on the trip if possible. It is important that you notify your guide about such medications and their whereabouts before setting off.

Last we would like to underline how important it is to dress according to instructions of the tour and the weather of the day. Always read the “what to bring” very well.
