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!

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

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.

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.

This was SO cool! I had never snorkeled before so I was nervous but all the staff were super nice and reassured me. My guide Gabe was very fun and made sure everyone in the group was having a good time, whoch I much appreciated as a solo traveller. And my driver James was very kind and made sure I had a comfortable trip to and from the Silfra. Highly reccommend for such a unique experience!
