5.00Can’t miss, otherworldly experience! Step out of your comfort zone and you will be rewarded with the lifetime of a memory! I promise you that any discomfort you feel from the cold on your face and hands is completely overpowered by the sense of awe you feel as you snorkel through Silfra and its crystal clear water. The guides we had were incredible (Diogo and Linn), couldn’t recommend them enough!! Would do it again in a heartbeat.
Great experience and Lillian is awesome!

5.00Had an incredible experience with Dive.is! Their entire staff was very knowledgeable and explained everything well to this first-time snorkeler. They had a very well-orchestrated tour and system for getting people from check-in to suited up and into the water and back. My tour guide, Anna, was fantastic; she made me feel safe trying this new experience and took wonderful photos of my group. The views were spectacular! I'd love to do it again!
