Tour description
Caving and Snorkeling 

Combining caving and snorkeling gives you the ultra experience of Icelandic nature. You will explore the hidden world of the lava fields on foot and underwater.

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.

You will snorkel under the UNESCO World Heritage site, Þingvellir national park  at the freshwater fissure Silfra, one of the best diving site in the world.

Silfra is about 60-63 meter where it is deepest. Silfra is a freshwater fissure and you can almost see end to end as the water is so clear. 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 depending on your interest. Adventure Vikings is the only company in Iceland offering wetsuit snorkeling and we really recommend you to do that as you will get more freedom in your snorkeling experience.
