Tour Description

lava formations tube cave

Lava formations all around

Going underground

After leaving Reykjavik we drive in a minibus for about 25 minutes and then we will 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.

The walk in the cave is an exciting journey and there are many things to see so we spend around one hour 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.

More about the cave...

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 our main concerns. There are no handrails, lights or any tools installed in or around the caves. We rely completely on the equipment we carry and it is important that people respect our guidelines.

After a great caving tour we head back to Reykjavík and drop you off around 11:00 at your original pick-up location, giving you time to have a nice day exploring Reykjavik's bustling city center. We then pick you up in front of your hotel for your Northern Lights tour at 20:30-21:30. Please note that food and beverages are not included on the evening tour.

Northern Lights

We check the weather forecast closely and set of into the night for the search of Northern Lights from the city.

We will hope for the best and be prepared if luck smiles on us. We will drive to beautiful locations somewhere on the south coast, we will get out of the minibus and check for the northern lights. We will go to locations where there is no light-pollution, so that we can get a good view of the Auroras.

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.

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

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.

Aurora Bonus

If the Northern Lights don't show up on your tour you can contact our sales team here and we will book you on the Magical Auroras tour, free of charge. Please remember to mention your booking number in the email.
