Silfra snorkeling and caving gives you the ultra experience of Icelandic nature. You will explore the hidden world of the lava fields by foot by caving in the Blue Mountain area and visit the UNESCO World Heritage site, Þingvellir national park and snorkel the freshwater fissure Silfra, one of the best diving site in the world.

Silfra is a freshwater fissure about 60-63 meters where it is the deepest and you can almost see to end of it as the water is so clear. The water is so pristine it feels like flying. No diving experience is needed as you will snorkel at the surface of the canyon. We provide all the gear that you need and offer snorkeling in wetsuit and drysuit all dependant on your interest. We however recommend the wetsuit as you will feel more free and be able to dive as well, no diving license is required. Not sure which suit to choose? Take a look at our blog post wetsuit vs. drysuit to help you decide.

The cave we will visit is called Leiðarendi. The 900 meter long lava tube offers unique rock formations, such as stalactites and shelves. Some light crawling may be required yet Leiðarendi cave has a rather easy access to the underworld wonders of the Icelandic lava fields.
