About this experience

Adventure Vikings offer caving in Leidarendi Cave in Iceland. You should definitely go on this tour if you want to see what’s underneath all the lava in Iceland. Together we will explore the hidden world of the lava fields as we will take you down to The End of the Road (I. Leiðarendi).

Leiðarendi is about 900 meter long and in there is about 150 meter walk towards it. The cave lies in fact in a circle. The cave is pitch black without light but you will get a helmet and headlight so you will easily see the wonders that the cave has to offer. You will see magnificent lava formations such as stalactites and drip stalagmites and have an underground adventure. You might need to hunch and crawl a bit but all in all the cave gives an easy access to the underworld of the Icelandic lava fields. The lava above the cave was formated more than 2000 years ago.

Cancellation for this tour

Free cancellation until 2 days before departure; no refund after that. If the operator cancels for weather or safety, you get a full refund or a new date.

If the weather cancels this tour

Iceland's weather is real. What usually stops this one is wind on the ridge or a change in eruption activity — civil protection decides, not the operator. Here is exactly what happens to your booking.

1Adventure Vikings decides, and tells us. Operators cancel when it is unsafe or pointless, and we back that call every time — we do not ask them to run anyway.
2We contact you by email, and by phone if your tour is the same or next day. You choose: another date if there is one you can make, or a full refund. There is no fee and nothing to argue.
3The refund goes back to the card you paid with, through Stripe, usually visible within a few working days. If this tour was one of several in your booking, the others are untouched.

What you do not get is the day back. If this is the only free day in your plan, put a spare day next to it — the planner leaves days free with the rest-day option. And if you want out because the forecast looks bad, that is your own cancellation: free until 2 days before departure, the operator's policy after that.

We had a most excellent driving tour of the Golden Circle. This included lunch at Fridheimar Tomato Farm which was fabulous. The tour was educational and highly enjoyable. I highly recommend this tour. Our guide was Gretar and he was an excellent tour guide.

We had a lot of fun with Adventure Vikings. The pick up was smoothly handled and given the snowy conditions I was glad not to be driving. We weren’t too cold at all thanks to drysuits (even though we looked like Patrick from SpongeBob!) and the snorkelling was super cool and easy. Thanks Gretar! Susan and Harry 🙂

We just got back from the Silfra snorkeling tour. It was incredible! Our guide Arnie was phenomenal. Everything was organized, educational and supported. We were very excited and had an awesome experience.!! Other than the not great weather with rain and chill… The experience was awesome and the water didn’t even feel cold because we were so prepared! You should go!! Our water photos aren’t ready yet or I would add them!

Best experience ever. And adventure Vikings are amazing. I had a change in travel plan at the last moment, but the team accommodated me very nicely and with understanding. Special thanks to Bjarki for being so responsive on email. Also thanks to Kaya, who has been an amazing guide through out the adventure. She has good knowledge about the area and also the activity. She later shared some of her favourite places in Iceland for us to visit, which were amazing. Also, the GoPro pictures were amazing and she is fun. I would recommend booking your trip with them.

Read before you book

Black & Blue tour: combo or book separately?The Black & Blue combo pairs Silfra snorkelling with the Raufarhólshellir lava tunnel. It saves €21 to €59 on booking the two apart, if you want both on one day.
Blue Lagoon transfer: private car, shuttle or taxi?A private Blue Lagoon transfer costs €107 to €232 per car. Under three people the bus is cheaper; with luggage or a late flight the car wins.
Guided day hikes from Reykjavík: which one to bookFour guided hikes from Reykjavík on the Reykjanes peninsula, €117 to €1,040: the Seltún trek, a volcano bus tour and two private options compared.

Lava caves — questions people ask

Which lava cave near Reykjavík is the easiest to visit?

Raufarhólshellir, sold as The Lava Tunnel, thirty minutes east of the city. It has a lit walkway and a one-hour guided walk (/experience/32545/ meet on location, or /experience/222055/ with pickup), so no crawling and no head torches. It runs all year. Viðgelmir in West Iceland is longer and quieter, an hour and a half away, and Leiðarendi is a proper caving trip with helmets and scrambling.

What is the difference between a lava cave and an ice cave?

A lava cave is a tunnel left when a lava flow drained out thousands of years ago; it is rock, permanent and open all year. An ice cave is a meltwater tunnel in a glacier, usually only safe November to March, and rebuilt by nature every year. Lava caves show colours in the rock, ice stalactites in winter and total darkness. Ice caves show blue light. If you are here in summer and someone offers a natural ice cave, ask which one.

Is lava caving suitable for children and older people?

The Lava Tunnel, yes. The main walk is on a flat walkway with lights and handrails, and children of most ages manage it. Viðgelmir has a good path too. Leiðarendi and the caving combos (/experience/268/) involve crouching, uneven floors and some scrambling, so the operator sets a minimum age; check the tour page. Anyone with a bad back or knees should stick to the walkway caves.

What do I wear in a lava cave?

It is around zero to four degrees inside, whatever the weather outside, and floors drip. Wear a warm jacket, closed shoes with grip and long trousers. The operator provides a helmet with a head torch where needed. For caving trips, wear clothes you do not mind scraping on rock; gloves help. The Lava Tunnel is easier on clothing, but it is still a cold, wet cave, not a museum.
