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!

Great Natural Experience - Amazing natural lava caves. Our tour guide was great too. We took our 70 yr old parents and it was ok. They skipped a crawling section but the rest was ok for them.

Fantastic driver - Voeran our transfer guide was amazing. He told us all the history about iceland and was very knowledgeable. He then linked it to the lava tunnel so we knew all the background information before thing part. The lava tunnel and tour guide in the cave was also good. Over all really enjoyed the experience. Can't wait to come back!

Very nice and unique experience. - The tour of the tunnel was longer then expected (which is good). Guide (Luis, sorry if I misspelled) was very friendly and funny, but professional, and was quite informative about the cave/tunnel. The cave, by itself, is natural, very interesting and unique. We enjoyed the tour very much.

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.
