5.00Our guide Adri was fantastic. He was super helpful and patient with our group while we put the gear on. He explained everything in detail and made it a great experience. It was a bonus that the photos he took turned out great.
It was a top priority, and our top experience.

5.00Exceeded every expectation I had. I felt fully informed, and perfectly safe. They kept us warm and (mostly) dry, while experiencing a unique and mesmerizing underwater landscape.

5.00Our guide Leo helped us gear up for this one-of-a-kind experience. It was super cold but we were warm in our wet suits. The views and pictures he took were out of this world. One of the most special things we did in Iceland. For families with children or people with limited mobility, the suits were very uncomfortable and tough to put on. For us, it was worth it!
This is a must do! Not as cold as you think!

5.00This trip was very well organized. It wasn’t as cold as you expect because you are so layered. You will miss a real adventure if you don’t try it.
Thank you, Armand!

5.00Hella cold in March, but so worth it. You wear a dry suit, not a wet suit so be sure to wear a solid thermal layer and double socks. The coldest part is getting out, but the view is unbeatable. We had Jana as a guide and the other group had James. They were terrific and did a great job of explaining the process to a bunch of people who had never done it.
