“This is the perfect thing to do if you want just a short adventure outside the city! The lava tunnel was unreal and highly recommend seeing it. It’s a short 45 min drive from BSI (the bus terminal) and you get about an hour inside the tunnel itself. Would do again in a heartbeat!”

“It is nice but if you have seen lava caves before it can be skipped for what it cost. The experience is not very visual - you are basically in a black hole hearing geological explanations. The guide, Joseph, was very nice and funny.”

“Great tour experience! I would recommend.

Climbing to top of the crater is literally breath-taking on a sunny day - and perfect for photos!”

Snorkel the Silfra fissure in Thingvellir, then explore lava tunnels at Raufarholshellir. Small groups, hot cocoa, free photos.
“We started going to the lava cave. The guide was very experienced and told us everything about the lava cave's history. We got to experience real darkness and finally were dropped off at some place to have lunch. Then it was time to head off to Silfra. I was so excited!! We got split up in smaller groups of 5-6, which was great. We had to get changed outside - it was freezing cold (but I expected that and for me it was part of the adventure) and it has been raining, but that didn't really matter, as our hair got wet in the water anyway. Taz has been an…”

“The setting for this visit was just perfect plus the weather definitely helped make it a memorable experience. It is a short drive on a small bus from Reykjavik. The guides were very informative on what to expect but also how to be safe. The cave is in the proximity of some beautiful mountains and picture perfect. If you are claustrophobic this is not for you. I was there in the morning tour. Be prepare to walk and crawl through small spaces.”
