Underworld – Caving Tour

All year Daily 1 hour Your hotel / guesthouse in Reykjavik Very easy Min 10 years old

Available all year long, this tour takes you to Iceland’s most spectacular Leiðarendi lava tube cave and craters. These beautiful, natural phenomena were created when the surface lava solidified but magma continued to flow in tunnels.

Leidarendi lava tube is considered to be a subterranean wonder world. The entrance is a small pit that leads down into the cave; the cave itself runs in both directions and connects in two parts so it runs as a line with a circle in the middle. There you will see natural stalactites and different rock formations making this a beautiful experience. The cave’s name translates to “End of the Journey”.  Cave Leidarendi is about 900 meters long and it is situated near a volcanic crater south-east of the town of Hafnarfjordur. It was first mapped in 1992.

The cave’s ceiling and walls are broken or collapsed in very few places and it is therefore easy to navigate. Sometimes the cave’s ceiling gets a bit low so you might have to crawl for a short distance. You don´t have to be afraid of caving in Iceland, Cave Leidarendi hasn´t changed in over 2000 years!
