Earth and Sky – caving and northern Lights

In a Super Jeep, search the Northern Lights and enter cave Leidarendi

Going underground

After leaving Reykjavik you drive in the super-jeep for about 25 minutes and then reach the lava tube cave, Leidarendi, a well known lava cave in Iceland. The cave is located in Tvibollahraun lava field, close to the Blue Mountains. The cave is easily accessible to all who can walk on uneven surface. Here's a peculiar lava formation called "The Rose"

The walk in the cave is an exciting journey and there are many things to see during the 1.5 - 2 hours exploring the cave and its colourful magnificence. The length of the tube is estimated to be 900 metres. You will see natural stalactites and different rock formations making this an experience of majestic and almost indescribable beauty.

Shedding light into earth's interior - simply amazing

In the backward section, the cave forks into 3 tunnels where lava falls and other spectacular lava formations can be seen deep in those tunnels that lead to huge chambers.  Lava tubes are natural conduits through which lava travels beneath the surface of a lava flow, expelled by a volcano during an eruption. They can be actively draining lava from a source, or can be extinct, meaning the lava flow has ceased and the rock has cooled and left a long, cave-like channel. Lava tubes are formed when an active low-viscosity lava flow develops a continuous and hard crust, which thickens and forms a roof above the still-flowing lava stream. Tubes form in one of two ways: by the crusting over of lava channels, and from flows where the lava is moving under the surface.

Sometimes during winter time some ice can form in the forward section of the cave so that almost every stone is coated with a thin crust of ice. Respect for nature and safety are all main concerns. There are no handrails, lights or any tools installed in or around the caves. You rely completely on the equipment you receive and it is important that people respect tour guidelines. After the caving tour goes hunting for the Northern Lights in a super jeep.

Northern lights

After checking the weather forecast closely the tour sets of into the night for the search of Northern Lights.

The solar activity puts on a magnificent show of Aurora Borealis as a result of frequent and massive solar explosions. Seeing them swirling and swaying overhead is simply an unforgettable experience; the lights are usually greenish yellow but white, red and pink lights may also appear. To watch the northern lights surrounded by the magical Icelandic nature is like walking into a storybook full of mystical beings and locations- you will never find such places or sights anywhere else.

Caving difficulty

The entrance to cave Leidarendi is a small pit that leads down into the cave; the cave itself runs in two directions and connects in two parts so it runs in a circle. The cave's ceiling and walls are broken or collapsed in very few places and it is therefore easy to navigate. Although sometimes the cave’s ceiling gets a bit low so you might have to crawl for a short distance.

This tour is suitable for all who can walk on uneven surfaces and at times, on all fours.


In the cave everybody use hand held torches, not headlights. This is because headlights are weaker than torches and it is difficult to point them in the correct direction.
