Hot Spring Snorkeling

Where few have been before

Snorkeling in bubbling hot springs is usually impossible as the water is far too hot, but the hot springs at the bottom of Lake Kleifarvatn provide us with the opportunity to do just that. Lake Kleifarvatn is hidden within a stunning volcanic landscape just 30 minutes outside of Reykjavík and only 20 minutes from the active volcano at Geldingadalir in Reykjanes peninsula. Talk about a unique tour!

Standing at the lake shore and changing into your dry suit, you will probably catch a whiff of the sulfur emitted from nearby hot springs and the total silence will let you forget that you are anywhere near civilization.

The underwater hot springs in lake Kleifarvatn have only recently been discovered and are about a 50 meter swim from the shore. Upon entering the lake you can see the white and yellow sulfur deposits on the lake floor. When we swim closer, you’ll begin to sense the environent around you changing as you approach the gas emanating from below the lake’s floor. We’ve heard this sensation described as similar to ‘snorkeling in a glass of Champagne’—the fact that you are snorkeling in a caldera is also impressive enough!

When back on land we will enjoy some refreshments at the shore before moving on to Seltún, a nearby high temperature geothermal area on land. In Seltún we will walk along the boiling mud pots and colorful sulfur deposits.

We highly recommend that you bring your swimsuit with you. Your next stop after this tour could be the nearby Blue Lagoon or at one of Reykjavík’s local geothermal pools where you can relax in the hot tubs and end the day in traditional Icelandic fashion.

Incredible GEOTHERMAL SNORKELING - the ONLY company in iceland to offer this incredible experience!

What can I say!? Mind blowing geothermal snorkeling at Kleifarvatn. It was the first time I had ever snorkelled and definitely won't be the last, and definitely not the last with dive.is.

  • I felt like a mermaid swimming amongst the streams of bubbles erupting straight from the centre of the earth, whilst floating above the glittering mineral deposits.
  • Completely tourist free experience. Just the 4 of us and the whole geothermal area to ourselves. Not another human or car in sight! Definitely an off the beaten track tour.
  • Perfect small group experience with an amazing guide - shout out to Jukka, who was incredibly friendly and well informed about the geology of the area and how the geothermal fissures in the lake formed.
  • WARMER WATER THAN SILFRA. And warm soup, fresh bread, hot chocolate and chocolate biscuits after!
  • Post-snorkel visit to the geothermal area Seltun - very similar to Hveravellir near Myvatn, without having to travel to the northeast! Perfect if you are only staying around the Reykjavik area.
    Could not recommend it any more highly!
