Don’t miss out!

Amaaaaazing! Absolutely loved it and would do it again. Great guides to work with, especially Jana. Took great care of everyone in our group. When I was floating along it felt like I was on another planet. Highly recommend!

Once in a lifetime!

It was a great experience. Guide Veli was great. Honestly, it is a lot of prep for a relatively short snorkel experience. 45 minute ride to the site, waiting for your turn and getting geared up takes quite a while, then waiting for your turn among lots of other groups using one launch pad was a lot. It's fun, it's gorgeous, it's invigorating, the DIVE team is great. Definitely do it!

Awesome Experience

This was an awesome experience! The whole crew was awesome, so helpful. Being over 70 they went out of their was to make sure we were comfortable with everything. The dry suit experience was easier than I thought but if you are claustrophobic you should think twice.

Super beautiful experience and an absolute highlight

It was super! Starting with the pickup at the harbor (we arrived by cruise ship), everything worked out super well. Very nice bus driver. We had great weather and drove through the national park to the Silfra Fissure. Everything worked out perfectly. You get dressed and snorkel in a small group. Our guide Elsa was great, super sweet and nice, explained everything wonderfully, and was always there for us. It is an incredible experience to snorkel in the glacial water, and the dry suits keep you dry and warm. Initially, your face and hands have to get used to the cold for a moment; it is possible that your hands might get a bit cold. Elsa takes the photos and she does a great job. At the end, we got hot chocolate and cookies and were brought back safely. The tour is highly recommended! THANK YOU!!!

Amazing experience

I hope this review reaches out to Konrad, our fantastic guide who deserves acknowledgement for his great job. Other than that, on the site there was written that during the transfer from Reykjavík to Silfra, some geological explanation would be done. Unfortunately, this was not the case; but other than this it was a fantastic experience.
