Top 25 Moments of 2025 | 10 Scuba Diving Silfra in Iceland The water was 33 degrees and absolutely freezing, but it was also the clearest water in the world. It is so clean you can take your regulator out and drink it. Every crack and contour felt unreal, like floating through glass. Getting to dive Silfra with my Italian brother Gabe made it even better. Sharing that experience together turned an incredible dive into something truly special. This is a must dive for every diver out there. #Silfr
