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. 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 150 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.
