Frequently Asked Questions

Q: Do I need any special equipment when visiting the tunnel?

No, we provide all necessary equipment such as helmets and lights. However, we recommend that you wear good hiking shoes (especially for the Extreme tour) and take note that the temperature inside the cave is around 0 – 4 degrees celcius (32 – 38 Fahrenheit). Water sometimes drips from the ceiling of the cave so wearing a waterproof jacket helps.

Q: Do I have to book the tour in advance?

We highly recommend you book in advance in order to guarantee a place for the hour you want. We do accept walk-ins as long as there is space, but space is limited on each tour so we cannot guarantee it is available unless you book ahead. For groups it is especially important to book ahead as it's unlikely we will fit a large group on a tour if they just show up. You can see the availability here on our website or call us to check if you have a specific time in mind. The standard tour runs every hour on the hour and sometimes on the half hour during the busy seasons. For the Lava Falls Adventure tour you need to book at least 1 day in advance.

Q: How do I get to the tunnel?

The tunnel is very easily accessed and is less than 30 minutes drive from Reykjavik. TheLavaTunnel is easily accessable in the winter time as well. Head east on road no. 1 and drive for about 18 km. Turn right onto road no. 39 (Þorlákshöfn) and drive for another 12 km. The parking lot is right by the road. The GPS coordinates are: N.63º 56.407 / W. 021º 23.742

Q: Is the Lava Falls Adventure tour for everyone?

No, it is not for everyone.  You need to be in good physical shape and be able to walk through rough terrain with big boulders without a difficulty.  You need to have a good balance and generally we recommend the Lava Falls Adventure tour only for people in good physical conditions and we don´t recommend it to those with back or knee issues. The age limit is 12 years old for the Adventure tour.

Q: Do you offer private departures?

Sure, please contact us and we can arrange a private tour for you, whether you are just enjoying this nature wonderland or if you want to shoot a video or even planning to get married in TheLavaTunnel!

Q: Do I need to be part of a group to come on a tour?

No there is not need, you can book the standard tour even as a solo traveler as we depart every hour on the hour. We will run that tour even with one person but you will likely be joining others booked on the same tour. The standard tour group size is usually up to 30 passengers.  If you book yourself on the Lava Falls Adventure tour, then you may find yourself in the company of others exploring the tunnel all the way to its bottom although the Lava Falls tours have maximum capability of 8-10 people.

Q: How long is the tour?

The standard tour is approximately 55-60 minutes in the tunnel. However, the Lava Falls Adventure tour is usually around 2,5 to 3,5 hours in the tunnel.

Q: Can I move my booked departure time without a penalty?

Yes, that is no problem. You can attend a different departure than you booked, as long as there is availability.

Q: Is there an actual flowing lava in the cave?

Flowing lava is an extremely hot liquid. On average, fresh lava can be between 1,300° F and 2,200° F (700° and 1,200° C).  Thankfully, there is no flowing lava in the cave or otherwise it would not be possible to enter it.  However, you will see clearly the path that the lava once flowed, some 5.200  years ago.
