Fodor's Expert Review Silfra

Most people visit Þingvellir for its historical and geological significance, but in this same place another perspective awaits those who don’t mind trading their walking boots and windbreaker for a dry suit and flippers. Named one of the top three freshwater dives on the planet, at Silfra you can snorkel on the surface of crystal clear water or dive to depths up to 30 meters. Exploring these underwater cracks is like entering another world: the silence is striking—a perfect companion to the vision of muted blues, bejeweled with silver globules of gas mushrooming to the surface from the divers below. An adventure in this underwater wonderland between the continents of North America and Europe leaves you with vivid images but no words. For tours with knowledgeable instructors, book with dive.is, Tröll Expeditions, or Arctic Adventures.
