Snorkel in the Silfra Fissure, Golden Circle

Such a neat experience! You have to wear thermal underwear of some sort and warm socks. You put on a suit, and then a dry suit over it. It is tight, and uncomfortable around the neck and wrists - but it's to keep the 2°c water out sooo it's worth it. There's a short walk to the entry point. We had to wait about 20 mins to get into the water because of other groups ahead of us. Once you are in the water, it naturally propels you and the suit loosens up a bit. You barely have to do work. Our guide was funny and nice. At the end we all drank hot chocolate and talked about the experience.

Great guide and staff. Wish it was longer. really cool experience.

Exceeded expectations. This was a highlight of the trip and one of my favorite travel experiences. You go in groups of 6 per guide so you get a really good experience and attention from the guide.

Very cool experience! Highly recommend doing it!

Did this with her two teenage boys. It was very cool. It was a bit cold, but not intolerable. The staff was awesome.

The Silfra Snorkeling was a unique experience and I'm glad we did it. The dry suit is quite an experience if you have not used one before, and while not comfortable, they work well in the cold water. The guide was great and took great care of us. We are not sure we would do this again, although one of our group would consider a scuba tour.

Leon loved this very unique experience! Unlike anything else he has ever done.

Carla was amazing. The water is clear (and cold). This exceeded our expectations. Being able to see where the tectontic plates come together is amazing.

Amazing. Staff was also helpful and made everyone comfortable with their gear. The water is cold…not sure this would have been as fun in the winter! Everyone enjoyed this.

The most unique experience - very special to be snorkeling between two tectonic plates! Our guide Gabriel was excellent, caring, funny and very friendly. He did a great job and gave us an experience that we will never forget. When you are in the water and snorkeling between the tectonic plates, it feels very special and you feel like pinching yourself!

I have not given 5 stars for this activity because I found that dive.is has taken on too many people and is not able to process this volume of tourists effectively. The expected 30-minute prep took 2 hours. Our 11am snorkel in fact started at 1pm. Our group of 6 people also had two issues with the equipment/dry-suits as two of them were leaking. There seems to be too much pressure on the guides to keep things moving and weight of numbers of tourists is too high. My strong recommendation is that dive.is review what is a realistic number of tourists and cut down a little bit. They should charge higher prices if need be but it is important to reduce the volume of people to keep it fun and enjoyable and safe.
