Underwater & Underground

Explore the amazing ways that geothermal and volcanic activity has shaped our landscape!  We will take you underwater and deep underground for the most unusual views of what happens when the ferocious forces unground meet the surface of our world.

We will first take you snorkelling through hot springs at the bottom of Lake Kleifarvatn. Lake Kleifarvatn is hidden within a stunning volcanic landscape just 30 minutes outside of Reykjavík. Don’t let the term “hot springs” fool you though. The lake is still very cold and you will put on a dry suit in order to stay warm in this remote lake.

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 environment 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 will then make our way to the fantastic lava tube called Leiðarendi where you will descend into the extensive systems of lava caves.  These caves, or tubes, were created during volcanic eruptions as molten lava flowed while also cooling at the surface.   These tubes now form an incredible underground world and are safe for exploration. You will be surrounded by fantastically odd rock formations and your flashlight will bring the phenomenal display of colors to light.
