About this tour, from the operator
The Silfra Fissure is more than a snorkelling site - it is a surreal passage between two continents! Slip into the clearest water on Earth and watch a hidden world unfold around you. You’re gliding through a cathedral of rocks and shimmering blues, surrounded by volcanic rock walls that drift apart 2cm every year. Few places on the planet let you feel so connected to the forces that shape the Earth. Our expert guides are trained to ensure your safety and confidence in the water, so you’re free to focus on the wonder around you. This is not a typical swim, it’s a once in a lifetime adventure into the heart of Iceland.
