We loved this experience! It was much cooler than what we expected, and much colder so dress properly. It’s amazing to see the colors and formations! I would do it again

A must to see

Lynton_G, Feb 2026
What a great experience this was, we all thoroughly enjoyed this and were extremely lucky that there were only 3 of us on the tour, the lady that took us was very informative but not too serious (keeping it at our level) really enjoyed it and would definitely recommend

Very cool & educational!

Blake_K, Jan 2026
This lava tunnel tour was MUCH cooler than we all expected it to be, and well worth the cost and the hour-long stop! Our guide was wonderful and hilarious as well. We learned a lot about how the lava tunnels are formed. Make sure to bring a good camera!

A great place for photos...

Sheila_C, Jan 2026
A great place for photos and to learn about the volcanic activity on Iceland. We paired this with a hike to see the lava fields and active volcanoes along the coast nearby. Highly recommend a volcano day on Iceland.

Magical

Leigh_T, Dec 2025
I have read some negative comments about this experience, especially on Google, but, personally, I really enjoyed it. Luckily, it was a quiet day so there were only 5 total in the group. The guide was very informative and explained things without being patronising and with good humour. We had the full hour, and more, giving us time to take photos. I’m more annoyed that I am not a good enough photographer to give the photos justice to the beauty of the tunnel. I’ve only not given it 5 stars as it is quite expensive but then again, it’s probably reasonably priced for Iceland.

Great, night time exploration

Camille_H, Dec 2025
Wonderful trip into the Lava Tunnel. I am amazed at the way Lava flows and the caves then created. I recommend this.

Brilliant experience

tracey_g, Dec 2025
This was a great experience with the family, a huge lava tunnel with very informative guide. Helmets with torches provided.

Cool experience

Jennifer_M, Nov 2025
Our family did the tour with our kids, age 7 and 9. It was perfect for these age groups, easy walking path but still able to see all the things. We had a great time! The tour guide was amazing !

The Lava Tunnel experience for first timer

SiongLye_L, Oct 2025
The Lava Tunnel tour was an amazing experience! The view inside the tunnel was absolutely stunning, and it was fascinating to see the different rock formations created by ancient lava flows. Our guide was very knowledgeable and made the tour both educational and enjoyable. I especially appreciated learning about the difference between a regular cave and a lava tunnel — for example, how sound behaves differently, since you don’t hear an echo in the lava tunnel. It’s those kinds of small details that made the experience so unique and memorable.

Great Experience

Matthew_C, Oct 2025
Really a great and unique experience of something natural near the city. We really enjoyed the semi guided experience and being able to explore. Great experience!

Lava cave tour

Dori_E, Oct 2025
Seeing the lava tunnel is a unique experience. It it very different than other lava tunes we have seen, like the ones in Hawaii. Our guide had a heavy German accent and we found him to be hard to understand. I think if he would not try to speak so fast we may have understood more of his words.

Cool 😎 experience Lava Tunnel in Iceland

Kevin_K, Sep 2025
The tour lasted about an hour and Meagan was a great guide. Very informative with some stories as well. Being able to explore this lava tunnel was not something I would be able to experience where I live.

The wonders below the ground

Sandra_K, Sep 2025
It was cold, wet, interesting, informative and surprising. When the guide shut off all the lights and we shut all our lamps off it was awesome just being in complete, total darkness. Our hearing heightened and we were able to hear the dripping of all the water. Fantastic!

Awesome Experience!

Kamryn_S, Sep 2025
It was so cool to see and walk through this lave tunnel. The guide was very informative and she gave such cool details about the cave. I really enjoyed this tour and would definitely recommend it to others.

Great tour of the lava tunnel

rshear, Sep 2025
We really enjoyed this one hour tour of the lava tunnel. The ground is uneven and rocky, but very passable. Our guide did a great job of explaining all the cool details of the lava tunnel.

Excellent excursion

Jennie_G, Sep 2025
The lava tunnel is amazing and definitely worth visiting if you have the time. Our guide was very knowledgeable and spoke very good English, as well as Catalon. He had a good sense of humor and kept his commentary very engaging.

Nice tour!

Lorie_M, Aug 2025
Great tour, amazing guide. Was fun to walk the trails through the cave and learn about the formation. Good bit of humor and engagement.

great tour! a must see!

Leslie_M, Aug 2025
It was very interesting and informative. I didn't realize there was a longer tour but we only had 1 hour so it was perfect. The guide was very knowledgeable and excited to share the history of the lava tunnel.

No thanks

Kat_D, Aug 2025
We never made to the tunnel. Trouble with rental car. Lost over 200 dollars. Could get back our money.

Raufarhólshellir Lava Tunnel Tour in Iceland:

Dallas_C, Aug 2025
Walking inside a lava tube is a truly uniqur experience. Once inside the lava tube, the guide explained the fascinating geology of the lava flows, the formation of the tunnel, and pointed out the incredible natural features like lava stalactites and multi-colored rock walls. The lighting inside is minimal and atmospheric, highlighting the raw beauty of the cave without overdoing it. Our guide was fantastic – enthusiastic, knowledgeable, and clearly passionate about volcanic science and Iceland’s natural history. The walk itself isn’t too strenuous. It felt safe throughout, and the group size was small enough that it didn’t feel crowded. Highly recommended if you’re into geology, adventure, or just want to do something completely different from the typical sightseeing tours. It's a literal walk into the heart of Iceland’s volcanic history.

Fun with Lava

Chelsea_L, Aug 2025
We had such a fun time and enjoyed the learning experience of the lava tunnel! Our guide, Alex, was super knowledgeable and funny and accommodating! Highly recommend!

Must do on your next trip

Kevin_E, Aug 2025
The Lava Tunnel is well worth your time. The tour guide was informative, funny and engaging. The tunnel itself is bigger than you think it’s going to be. The path was easy enough for my 3 kids to walk. You won’t regret taking this hour tour.
