The tour begins with a thrilling snorkeling adventure at Silfra Fissure. The fissure is located in Thingvellir National Park on a rift valley between the North American and Eurasian tectonic plates. Silfra was formed by a powerful earthquake in 1789, and the tectonic plates continue to drift apart at a yearly rate of about 0.79 in (2 cm). So when you go snorkeling you will actually be swimming between two continents!
To get to your Silfra snorkeling location you can either choose to be picked up from Reykjavik or meet us on-location at Thingvellir, where our friendly guides will be waiting for you.
Once you're onsite you'll be given all the necessary snorkeling gear and drysuit. Don't have any prior snorkeling experience? No worries. Our knowledgeable guides will walk you through everything you need to know. The only requirements are that you are able to swim, are in good health, and have an adventurous spirit.
For the tour, you'll swim in the "lazy current," a glacial water stream that flows calmly in the fissure. The crystal water has been filtered for decades by lava rock and is so pure you can drink it. Marvel at the vibrant blue and green water shades, orange seaweed, and spectacular rock formations. The water at Silfra boasts 100-meter (328 ft) visibility, so you'll have the perfect conditions for exploring the geological wonders below.
- Silfra Big Crack is the narrowest and deepest section of the fissure at 394-ft (120 m) long and 147ft (45 m) deep. Along the passage are various caverns and swim-through holes.
- Silfra Hall is where the fissure widens out and leads into a 26 ft (8 m) wide and 46 ft (14 m) deep area. The bottom of this 'hall' is covered with giant rocks, some half the size of a car!
- Silfra Cathedral is 328-ft (100 m) long and 75-ft (23 m) deep. The area has such a strong current it almost feels like you are flying.
- Silfra Lagoon is 16ft (5 m) deep and offers the best visibility. Here you’ll find the most dramatic views of the fissure floor and turquoise blue water.
After you dry off and change, enjoy a treat of hot cocoa and cookies.
