Lava Tunnel Tour
A good tour of a Lava tunnel . Very interesting and worth taking even if you are not into volcanos. Well conducted and informative. The tour length in time was just right. You have to be able to do metal grated stairs and walkways. There are some rock areas used as stairs as well. My wife and I are fit and in our 70's. We had no problems. You can hang back a bit if you need to take your time.
Response from the operator: Hi there, good to hear this. Just the right length and interesting even for non-volcano people is a strong endorsement. Glad you and your wife enjoyed it. Arctic Adventures Team

Well worth the experience...
Well worth the experience We had a great guide knowledgeable and informative and fun If you don’t have much time a good one to choose

Our afternoon underground excursion was worth the price of admission.
The booking was easy with no issues. Transfer from our hotel to the bus terminal was convenient and from the activity site back to our hotel was direct with no transfer involved. The tour guide was outstanding, answering all of our questions and adding appropriate history of the cave experience. We wish we could remember her name.
Response from the operator: Hi Tom, thanks for sharing! The lava caving day works best when the logistics get out of the way and the guide can focus on the cave itself, so it's great to hear both came together. The history side of it is one of our favorite parts of the tour. We'll pass your note back to the crew. Arctic Adventures Team

A great morning trip, well organised and our 8 year old loved it.

We are happy to hear that your lava caving adventure was such an exciting and enjoyable trip for you and your family. It is fantastic to know that everything was well organized and that your 8-year-old loved the experience, that is what we always aim for. Thank you for taking the time to tell us about your wonderful experience. We would love to have you join us again for another memorable journey in Iceland. - Arctic Adventures Team

Amazing experience but expensive
Our tour guide Juan was amazing and the lava cave was a great experience. Juan was very knowledgeable, funny, and interactive with the large group. It was a little pricey being $100 for an hour but everything else was great.

Why this scores 69
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Lava Caving Experience: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Reykjavik.
How much does Lava Caving Experience cost?
+
Prices start at $41 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 Caving Experience take?
+
Plan for about 1 hour 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 Caving Experience worth it?
+
It holds an Outty Ranking of 69 out of 100, which we label "Solid Choice". That score blends traveler sentiment (4.8/5 across 29 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 Caving Experience?
+
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 Caving Experience suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 1-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Lava Caving Experience?
+
Around 10 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 1-hour experience runs outdoors or after sunset.
Where does Lava Caving Experience 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.
