Full description
Combining snorkeling and caving 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 meters at its 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 dependant 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.

Amazing experience!

We were a group of 5 so we had the guides to ourself which was really nice and gave us a more personal experience. Our guide was Bryndis, she had both knowledge about the caves and silfra so she had no problem answering all our questions. We also really appreciated the tips she gave us for the rest of the holiday. Would definitely recommend both the activity and Bryndis!

WOW what an experience, so great and yes the water is cold, but not too bad at all (2 degrees but feels less cold) The getting out of the water and taking the suite part of is the worse part, but the team makes it go as fast and smooth as possible so you can jump in your own warm clothes again. Thank you Veronica, I'm looking forward to the pictures you took!
