Snorkeling in Silfra
Tour Description
Contact us on info@troll.is if you wish to book a Private Tour
The Silfra Fissure is located in Thingvellir National Park, a UNESCO World Heritage site. Once you arrive there, you will listen as your experienced certified PADI Dive Master provides a safety briefing. Then, you will receive all of the necessary equipment for snorkeling in Silfra, including neoprene hoods and gloves, a thermal undersuit, a drysuit, and of course mask, snorkel and fins. This equipment will keep you floating throughout your time in the fissure, as well as offering a protection against the cold glacier water. Once in the water, your eyes will meet the incredible shades of blue so prevalent in the fissure, as well as the natural underwater flora of canyon walls.
As you are swimming you will have the opportunity to move across continents, as you will be swimming between the North American and Eurasian tectonic plates, which is one of Thingvellir’s most famous characteristics. You will meet Silfra Hall, which is the widest section on the fissure and then the majestic Silfra Cathedral, its deepest section. Even more, the stunning shallow oasis will be presented before your eyes at the end, “the Real Blue Lagoon”.
Upon exiting the water, you’ll be invited to warm up with hot chocolate with your friendly guide. After the tour is over you will receive the free GoPro underwater photos in your email.
You get the option to book a transfer from Reykjavik as an extra.

Join this unforgettable tour to see and experience the world’s rarest natural wonder - Iceland’s majestic glacier.
Glaciers formed during our previous ice ages, when temperatures dropped worldwide. Nowadays only a few countries in the world can enjoy the stunning glaciers - including Iceland.
Sólheimajökull is a beautiful outlet, which is the most accessible glacier from Reykjavík.
It is also known for being the Glacier of Fire & Ice, because of all the ashes covering and mixing up with ice from the previous volcanic eruptions. Underneath the glacier lies an active volcano Katla, which erupted last time in 1918.
It is believed that Katla should erupt within the next few decades, therefore completely melting the ice. However volcanoes are highly monitored in Iceland, making it absolutely safe to travel in the area, hike on a glacier, and explore the wild ice caves.
