5.00The equipment provided kept us warm and dry. Our guide Quim was the best! He made sure everything was perfect before getting into the water. His excitement and enthusiasm for his job was obvious. He loved what he does. We had an experience of a lifetime. One we won’t forget.

5.00If you do one thing in Iceland, it should be this. Highest recommendation. Groups are limited to six people (I think that's Silfra's rules) which makes for a very personal experience. Our guide was so thorough and friendly. The photos he took were incredible. I had no experience snorkeling previously and should add, it's taxing on the body. The medical waiver they send is legit. Anyone can do it, but just know it's more than just floating there. If you do this, make sure to take a sip of the water! The best I've ever tasted.

5.00Superb experience. Well organised and really enjoyed this. It's a phenomenal experience. Our guide Sara was superb and explained everything so well as we went. Don't be put off by the water temperature. You can't really feel the temperature because the suits are that good! You do feel it in your hands / face but I would do it again without question. At the end take a swim in the lagoon to the other mini-silfra and go thru the rocks - so amazing.
Such an amazing experience

5.00Efficient pickup and everything is organized (it’s very important that you listen to all the instructions). Staff were super friendly and our guide Flor was also very friendly and professional. It’s such an amazing experience the ester was icy cold def wear thermal underlayers before you leave hotel that day (you won’t have a chance/place to put them on at the site). Your clothes stay completely dry if you listen to their instructions. But warn you the water is icy cold be prepared to have frozen hands and face. But the view was amazing and they take photos of you and share them back with you.
Once in a lifetime

5.00You do not feel cold so don’t let that stop you. It was so crystal clear and an experience you can’t get anywhere else. Alex was an awesome guide. He had to deal with our group of over 40’s age group and was always there to help.
Eloisa worlds best tour guide.
