Silfra Snorkeling Tour: 3 Hours in Glacier WaterSnorkel in the Silfra Fissure at Thingvellir National Park, a UNESCO World Heritage site, where you swim between the North American and Eurasian tectonic plates in water so clear the canyon walls and underwater flora are visible throughout. A PADI Divemaster guide leads the 3-hour snorkel in a small group, and you receive a thermal drysuit, neoprene hoods and gloves, mask, snorkel and fins. You must be between 12 and 69 years old, comfortable swimming, and physically fit; you drive yourself to the meeting point. Free GoPro photos from underwater and above water are emailed after the tour, along with hot chocolate and a chocolate bar.Is it for me?Book this tour for a morning or afternoon when you want to stand in one of the world's few places where you can physically swim between two tectonic plates—the small-group format and fixed timing mean the day stays manageable, and the guide handles the logistics so you focus on the moment in the water.

The water comes from Langjökull Glacier and travels through lava before reaching the fissure, creating an underwater landscape found nowhere else. Your guide photographs you underwater at no extra cost, and hot chocolate and cookies warm you up after.Is it for me?Swim between two continents through Earth's clearest water, where volcanic rock walls frame a surreal passage that reveals the planet's geological forces in real time—a natural extension of your Golden Circle route.
