Cool Experience

I saw folks doing this experience nine years ago and finally came back to do it myself! The tour was very well organized, we were provided with all of the gear to keep us as warm as possible, our guide was informative and took good photos! It wasn't as cold as I expected, but it was indeed cold. I'd highly recommend!

Very nice experience

We had a very nice experience. Our guide Belu was very friendly and explained everything perfectly fine so every form of nerves were gone immediatly. The activity itself was something we had never done before and was very fun. We stayed in the water for around 30 minutes and could see everything perfect. I would reccomend this very much if you love to explore!

Unforgettable

It was definitely an amazing experience! I was really nervous about my limited swimming skills, the cold water, and everything that came with it, but it turned out even better than I could have hoped for. Nothing was planned at all — we literally visited the park on Monday and spontaneously decided to do this on Thursday before heading back! Steven our guide was fantastic and made the whole experience feel safe, fun, and unforgettable. 100% recommended!!

Snorkeling at Silfra

Our guide, Belu, was tops. She used clear instructional language and kept a light and humorous approach. She kept everyone safe and comfortable. She did an amazing job
