The most unique experience of our Iceland trip. - The whole thing might sound scary but it's a really once in a lifetime experience. The drysuits really do keep the water and cold out plus you'll really float along so there's no danger there. And the views of the Silfra fissure are just spectacular. Also have to call out our guide Diogo who was fantastic throughout the day and made the experience all the more better.

Beautiful and incredible landscapes and amazing experience. - This was an amazing trip right from pick up. The views and the sunrise as we drove from Reykjavik to Silfra were incredible. When we arrived everything was explained clearly and was well organised. It’s a bit tricky getting into the suits inside the van when everyone is in together but worth it for the experience. I had some issues with my mask but the guide was helpful and tried to sort it for me. Top tip is to wear good socks and thermals as this will keep you warm under the dry suit. It is truly beautiful and clear under the water and definitely worth seeing. Wish we had more time to look in the area around the lake as well but that would be my only slight issue.

Would do it again in a heartbeat! - Amazing experience! No where near as cold as I was expecting! Visibility was great. All the guides were super fun! Had fun with us, each other and other groups. Would love to do the deeper dive next time!

Super amazing!! - This was such a cool experience!! It was freezing the day I went, but I warmed up pretty quickly with the hot chocolate they provided after. I got the tour with the add on of the photos but I saw that you could pay to get them after the tour if you didn’t book the photos originally. I definitely recommend bringing an extra pair of warm socks & warm thermals to wear under the dry suit!

Amazing Family Fun - The experience was fantastic! Anticipation of the cold water soon passed when we entered the water. Gabe was a great guide & all the additional help/prep for the swim was top notch from Dive.IS!

Really great experience. - This was an awesome experience! Pick up at my bus stop and travel to Silfra we smooth and relaxing. The guides were really friendly and knowledgeable. It was my first time in a dry suit and they walked you through all the steps and helped. They were also really clear with instructions and how the snorkeling experience would go. There was plenty of time allotted and it didn't feel like you were being rushed through. I believe my guide was CG on 12/3

What a fun experience! - I enjoyed the experience. It was smooth from pickup to putting on the gear, getting instructions from the guides & snorkeling to returning back to my drop off location. I thought I would be cold, but the dry suit kept me warm... and dry. The water was beautiful and I definitely recommend.

An unforgettable experience - The whole process of service was very professional and very kind, especially led by my coach Quim, who was very patient with the guidance and with the enthusiasm, it was quite not easy because they were repeating these things every day and he was also grateful for our arrival and choosing this experience (diving) that allowed him to engage in the activities he loved all the time. Quim reflects the height of the coach.
