What a blast! We loved the authentic caving experience! It does require some climbing - but I am not in great shape and did just fine! Our guide was friendly, encouraging and knowledgable. Our small group of 10 was the perfect size. The snorkeling was awesome too! What a view! Do this tour!

Worth every penny! This was one of the highlights of my trip. Before I went I thought that it was kind of expensive, but after the day was over I realized it really wasn't. The water is unbelievablely clear and even though the water is cold I never once felt cold myself. Absolutely AMAZING!!!!

This tour was fun, a little bit challenging, and a great way to see parts of Iceland beyond your usual bus tour.

Juan was a great guide - he picked us up from our hotel promptly and took us straight to the National Park to snorkel with the other guests in the small tour. Getting suited up in the dry suits was a bit of a long process, but Richard and Juan explained everything and made sure everyone was comfortable before going in the water. They both had some great tips for how to deal with the cold and where to look to see the best views underwater. I've never seen water that clear or felt it that cold!!, and saying you snorkeled in the continental divide is pretty awesome.

After a brief lunch stop, we were off to the lava tubes on the other side of Reykjavik - Juan told us all about how they were formed, helped us through the tight spots in the tunnels, and made it a fun experience with a few stories. The lava tubes were fascinating to see up close, and this was one of the more authentic caving experiences I've seen.

It was amazing!! it is a life time experience. Before the tour I was scared that I was going to freeze my soul and get sick (I did it during the winter), but the dry suit really keeps you warm. The guides are amazing, they are really professionals and know what they are doing. I really had a fantastic time, I'm so glad I decided to do it, and I would recommend it to everybody.

This tour, with Arctic Adventures, was a truly amazing adventure. With very knowledgeable and friendly guides we walked through a lava tube and then went snorkeling in Silfra in a fissure with one of the clearest waters in the world. Getting into a dry suit is not easy but definitely worth the effort!

The trip was great. The 'cave' was interesting in the fact one cannot walk in lava tubes in too many places - worth doing it once. The snorkeling was fantastic especially when the sun came out and shone through the water. I was expecting it to be very cold but the down undersuits and dry suits really worked. Well worth the trip. Would love to do the dive next time if we make it back to Iceland.

Loved it but my hands burned so much from the cold it was hard to enjoy for the full a mount of time. Guides were outstanding both caving and snorkeling . I wonder if hand warders could have helped

Fabulous tour and highly recommend even during winter. Was the first time I snorkelled in a dry suite and apart for my hands and face going numb due to the 2 degrees water. The experience of snorkelling in the clearest water I have ever seen was amazing. Was the highlight of my Iceland trip.

Anticipating the full eco-adventure event, this tour delivered 5 stars. The staff were very knowledgeable of the area/history and displayed a high level of expertise/safety in coordinating the snorkeling and lava tube cave exploration. Both events need a moderate level of fitness. I am 60 years old and my wife is 53. My wife had never put on a dry suit, but the staff went over and above to assist and made sure the "old folks of the group" enjoyed the tour to its fullest.The lava tube exploration was superb and experiencing "total blackout darkness" in the middle of the cave was something I will never forget.We will return to Iceland to further our experience of this country.

Snorkeling in Silfra is definitely one of the most exciting things I've ever done!
Walking through the lava tube cave was fine, but it was pretty tame.
We spent the morning driving to the cave, walking through the short cave and checking out some of the Iceland scenery. It was a super windy day, so instead of a picnic we ate lunch in the van as we drove to Silfra. The sandwich was amazingly tasty!
Once at Silfra we stripped down to our skivvies, or leggings and t-shirts (guys outside, gals in the van - no changing rooms in the parking lot). Then we put on cozy "teddy bear" suits, which were basically like children's snow-suits, a big one piece down suit. Then the diving socks, then the dry suit with built on boots goes over everything. Hilarious watching everyone put these on, they can be a small struggle - with the rubber cuffs at the wrists and neck to keep the water out. Then the diving head piece and gloves. The suit, especially the rubber neck lightly squeezing your throat can be a tiny claustrophobic, but you get used to it before you get to the water, so it's ok.
Finally with flippers and snorkel mask in hand we walked to the waters edge, climbed down metal stairs and began floating effortlessly on the glacier water.
Basically only the skin around your mouth is exposed to the water, which goes numb very quickly - so the 50 minutes in the cold water is not uncomfortable at all.
The visibility is incredible and the colors are stunning!
After we got out of the water and walked a short way - we had an opportunity to jump off a little cliff into the water - a total rush!
Such an exciting thing to float between two continents!

My family (all adults) loved this outing. I especially appreciated the careful and sensitive way we were treated, since we were all absolute beginners. The staff were well informed and helpful, ensuring that everything went smoothly. This is what we come to Iceland for: experiencing the unique geography. I will say that I am quite out of shape, so I found the cave exploring to be a bit of a challenge - but it simply meant that I had to go a bit slower. Good hiking shoes a must for the cave; there are loose and slippery rocks and boulders. For snorkeling: my street clothes were bone dry inside the dry-suit, didn't even need the extra change of clothes, but I may have been lucky.

Absolutely brilliant. Ali, the guide, was top quality guy, ensuring that we had a great time. The snorkelling was amazing, beautiful crystal clear water which you could drink freely. We got a good hour or so. The caves were fun. Be prepared to crouch and squat. Quite tiring, but very enjoyable.

Very thoughtful group and the snorkeling was very interesting. However, it would best for someone who wasn't over 60 . . . need to be nimble.
