5.00This was a once in a lifetime tour. The guide Sara was fantastic. She was so knowledgeable and helpful. The tour was something to behold. The water was crystal clear and the experience was incredible. Please don't let the thoughts of the frigid water deter you. It is cold BUT after a few minutes you don't even know it. You should put this on your list of must trys

5.00Wow! This was such a unique and cool experience. We drove through a yellow weather warning to get here from Rekjavik but it was not terrible as it wasnât windy just snowy. Super worth it. Our guide, Quim, with Dive.IS was wonderful. Though the conditions were snowy and cold, the vans where you change are warm and they have a smooth system setup. This was the favorite activity for 3/4 of our family and definitely an incredibly unique and thing that you can only do here! Very Highly recommend!
An experience not to miss

5.00We had such a good time. The instructor was great and helped make my wife feel comfortable She wanted to back out before getting into the water. She was so happy she went. We were not cold at all. We'll worth the trip. Do not hesitate. Do it. Even if you cant swim. The suit keeps you a float.
Guides Were Awesome and Very Helpful

5.00This was a true once-in-a-lifetime experience!! My teenagers and I were a bit nervous, but our guide (Papi) was incredible. It took a while to get suited up (and the strip around my neck felt tight at first), but once we were in the water everything else disappeared as we floated along enjoying this amazing location. While there were several dozen people signed up for our time slot, each guide only had about 4-5 people in their group to ensure everyone's safety.
