About this tour, from the operator
You'll arrive at Thingvellir National Park, a UNESCO World Heritage site. Once there, you'll take a short journey through the volcanic, moss-laden fields of the park. Here, you will listen as your friendly and experienced PADI Divemaster guide.
Later, you'll receive all of the necessary equipment for snorkeling in Silfra, including neoprene hoods and gloves, a thermal drysuit, snorkel and fins. The equipment will keep you buoyant throughout your time in the fissure, as well as offering a protection against the water.
Once in the water, your eyes will meet the incredible shades of blue so prevalent in the fissure, as well as the natural under-water flora canyon walls. As you are swimming you will have the opportunity to swim across continents, as you will be switching back and forth from the North American and Eurasian tectonic plates. After the tour GoPRO pictures will be sent to you by email for free.
