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.

We had a great time doing the Silfra swim experience. Luca was a knowledgeable, attentive and supportive guide who made the whole experience fun and easy to enjoy. The water is definitely cold, so be prepared for that, but it’s absolutely worth it for such a unique experience. We’d also recommend planning ahead and bringing a second spare layer of thermals (top and leggings) to wear under the dry suits for extra warmth and comfort. Overall, a fantastic activity that we would highly recommend.

What an incredible experience for my family of 4. For a geology nerd like myself, and having the opportunity to snorkel between this fissure was pretty incredible. WE booked the 8:30am experience, and we were the first people to enter the fissure for the day. It was calm and the whole time we felt unrushed. Jaoquin, our guide, was simply incredible and helped my family be at ease. The dry suits, keep you dry and warm, but they can be bulky and awkward. My family of four, including my 12 and 13 year old daughters loved the experience and again, Jaoquin was great with them. The dry suits keep you warm and dry. Your face gets cold and numb, but both my wife and I after the experience, commented how our mid 40 year old wrinkles had disappeared for the rest of the day, so we'll take it as a win. We had an incredible experience and we thank the entire troll.is team for helping us discover the beauty of Iceland and Mother Earth!

Amazing snorkel tour between the continents. Kevin was excellent in his pre experience talk and during. A unique natural wonder. Stayed dry the entire time. The clarity of the water was remarkable. We did not see any fish but the experience was enough.
