Tour Description

lake kleifarvatn diving

Diving in a geothermally active environment

The landscape is stunning, only 30 minutes out of Reykjavik and one can experience complete silence in the most beautiful surroundings. In order to get to the dive site we will have to take our 4x4 dive bus, since rough and rugged tracks are the only route to this site in the middle of nowhere.

We park the dive bus close to the beach and walk down to the water to give you a briefing on this geologically unique dive site. If the wind direction is right, we will already be able to smell the hot springs.

See the gas bubbles come up in between sulphur deposits on the lake floor

We put on our gear and walk to the entry point. When walking into the water to put on fins and mask one can already see the white and yellow sulphur deposits on the bottom of the lake and the gas bubbles coming up in between.

In the central area of the hot springs there is a hole in the lake floor where a lot of water and gases flow up. When diving into this hole, one has the feeling of diving into an earthquake because the air bubbles coming out of the ground create pressure which makes the rocks vibrate. Divers can feel these vibrations deep into their bones. A very special experience!

After the dive we will pack our gear together and drive down the rough and rugged tracks to Krysuvík, a geothermal hot spring area nearby. In Krysuvík we will marvel at the mud pots and hot springs and the colourful sulphur deposits before we make our way back to Reykjavik.
