Hot Spring Diving Tour

Diving in bubbles like a champagne glass

Diving the Devil's jacuzzi

The underwater hot springs in Kleifarvatn lake have only recently been discovered and the bubbling springs are just a 100 meter swim from the shore of the lake.

Only a 30-minute drive from Reykjavík, Kleifarvatn lake is nestled within an impressive volcanic terrain. One can experience complete silence in this stunning landscape. As there are only rugged tire tracks that lead to Kleifarvatn, we take our 4×4 dive bus equipped for this frontier diving adventure.

Your briefing will take place on the shores of Kleifarvatn. Depending on the direction of the wind, you might then already smell the nearby hot springs.

At the lake’s entry point, you can already see the white and yellow sulfur deposits on the lake floor and the gas emanating from below the lake’s floor.

In the center area of the hot springs is a wide caldera that releases large amounts of warm water and gases. When entering into this space, you may have the feeling of diving into a gentle earthquake because the air bubbles coming out of the ground create pressure that causes the rocks to vibrate. Divers can feel these vibrations deep into their bones if the activity is strong enough that day.

After the dive we will travel to Krýsuvík and Seltún, a nearby geothermal hot springs area. In Krýsuvík we will visit the boiling mud pots and the colorful sulfur deposits.

We will then make our way back to Reykjavík. We recommend that you bring your swimsuit with you as and we can drop you off at the Blue Lagoon or at one of Reykjavík’s local pools. Here you can relax in the hot tubs and end the day in traditional Icelandic fashion.
