About this experience
Want to see what's underneath all the lava in Iceland? Then join us and explore the hidden world of the lava fields at The End of the Road, Leidarendi Cave. Leidarendi is a pitch black, 900 meter long circular lava tube, showcasing lava formations such as stalactites and stalagmites, along with surprising colors. A lava tube is created after a volcanic eruption when the lava has hardened on the surface, but magma still flows underneath. When the flow of lava ceases and the rocks cool down, a long hollow cave is formed - this natural wonder is called a lava tube. Leidarendi is less visited than other lava tubes is because of its structure inside. It is not a cave that has proper wooden planks for walking on therefore good sturdy hiking boots are recommended. It has some optional areas where you can crawl through allowing for a more adventurous visit but there are other areas that are accessible for and easier journey and yet end up at the same place, making it a loose figure of 8.

Under the volcano
A great little trip close to Reykjavik. Our guide Gretar was very knowledgeable and taught us a ton about volcanoes and lava tubes. It's a little claustrophobic sometimes, but the colors below are worth it. It was a physical experience, with climbing and crawling. So glad we were able to do this.

Good small afternoon trip
The pace was good for a varied group of all capabilities and the return with the tightest gap (not that bad) was optional. If you’re very tall it might be a little tough to be slouched over in some spots. Don’t leave anything behind!

Awesome experience
We went on the lava tunnel caving tour with friends and it was awesome ! We had the chance to have a wonderful guide, Gretar !! I can only recommend to book this tour with him !
via Tripadvisor
The cave is not far from Reykjavik.
It is difficult to walk inside the cave as the ceiling is very low. You have to crawl many times. It’s a good experience to see the lava cave.

Why this scores 68
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Lava Tunnel Caving with Transfer | Small Group: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Reykjavik.
How much does Lava Tunnel Caving with Transfer | Small Group cost?
+
Prices start at $91 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Reykjavik usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does Lava Tunnel Caving with Transfer | Small Group take?
+
Plan for about 2 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Reykjavik is not rushed.
Is Lava Tunnel Caving with Transfer | Small Group worth it?
+
It holds an Outty Ranking of 68 out of 100, which we label "Solid Choice". That score blends traveler sentiment (4.8/5 across 17 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Reykjavik, and how flexible the cancellation terms are.
Can I cancel or reschedule Lava Tunnel Caving with Transfer | Small Group?
+
Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.
Is Lava Tunnel Caving with Transfer | Small Group suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 2-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Lava Tunnel Caving with Transfer | Small Group?
+
Around 6 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Reykjavik can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.
What should I bring or wear?
+
Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Reykjavik and add a light layer if any part of the 2-hour experience runs outdoors or after sunset.
Where does Lava Tunnel Caving with Transfer | Small Group start and how do I get there?
+
The exact meeting point and directions are on your voucher once you book, and they sit in central Reykjavik within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.
What are the best things to do in Reykjavik?
+
On Outty we rank every Reykjavik experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Reykjavik Food Walk - Local Foodie Adventure in Iceland, Small-Group Golden Circle, Blue Lagoon with Ticket & Kerid Crater, Reykjavík Small group Walking Tour - by CityWalk. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.
When is the best time to visit Reykjavik?
+
Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.
How many days do you need in Reykjavik?
+
Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.
Do I book through Outty or through the operator?
+
Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
