Activity Snapshot
Activity description
Explore the longest lava tube in Thingvellir National Park as you travel through the underground passages linking Litli Björn to Vörðuhellir. Located in the Golden Circle, this lava tube is 1100m long. For 9,000 years, this passage has remained intact, offering the chance to observe the rock formations caused by volcanic activity thousands of years ago.
Just an hour's drive from Reykjavik, Litli-Björn and Vörðuhellir are within easy reach of the main sites of the Golden Circle. Litli-Björn was discovered in 1987 and was considered a single cave until a passage linking it to Vörðuhellir was discovered. It then became the largest cave in Thingvellir National Park!
This caving excursion in Thingvellir Park is suitable for adventure-seeking beginners as well as experts looking to find out more about Iceland... Try your hand at finding precious stones, and take one of the most adventurous routes in the country! With the light of a torch, you'll make your way through these underground caves standing up and stooping. Most parts of the lava tube have not been geologically altered and have been preserved to maintain the authenticity of the site!
Accessible from the age of 5, this accompanied hike will have you bending down to explore every nook and cranny of the lava tube linking Litli Björn to Vörðuhellir.
