Depart from Reykjavik city centre by bus for Thingvellir National Park, a 40 minute scenic drive on the famous Golden Circle Route.

THE VENUE: THINGVELLIR NATIONAL PARK
Sited on the tectonic plate divide, Thingvellir is a volcanic rift valley filled by lava flows. These are split by deep fissures, formed as the North American and European plates are forced apart. Some are visible on the surface, while others, like the stunning Silfra, are filled with the crystal-clear water. This spectacular landscape is the setting for your underground and underwater adventures.

THE CAVING
The Gjabakkahellir cave is a perfect example of an Icelandic lava tube. Lava tubes are the arteries of a volcano, transporting molten lava from the crater. When they empty at the end of the eruption, you get a network of tunnels left behind. They are usually not very deep, but can be hundreds of metres or even several kilometres long.

Arriving at the mouth of the cave, you'll be kitted out with helmet and headlight. After a briefing with your guide, the adventure begins. Exploring this underground wonderland is mostly quite easy as you venture from one chamber to the next. Each has a fantastic array of colours and formations, including beautiful stalactites, so don't forget your camera.

THE SNORKELLING
Back in the open air, there's time for a packed lunch before heading for Lake Thingvallavatn. Here the deep Silfra fissure cuts through the lava bed, gently feeding Iceland's largest natural lake. You'll slip into a dry suit and equipped with fins, mask and snorkel, ease slowly into the water. It's cold but gin-clear and filtered to perfection by layers of basalt.

Snorkelling on the surface you'll drift gently suspended above the fissure, gazing down through ethereal shades of blue into its depths. It's a relaxing but also incredibly thrilling experience. Because the water is so clear, the visibility is astonishing.

At the end of this adventurous day out, you'll return to Reykjavik.
