Our adventure starts with the black as we explore the hidden world of the lava field under the Þingvellir National Park. The park is located in the tectonic rift valley between America and Europe and littered with quirky, interesting lava caves. Walking down into a cave and discovering the marvels that volcanic activity has created in the past is a trip that everyone can do. The Raufarhólshellir cave is a perfect example of an Icelandic lava tube and is situated in one of the most active volcano areas in the world. After the cave you have time to grab lunch before moving on into the blue and your second adventure.

Warm and waterproof outdoor clothing, gloves, warm undergarment clothing (fleece/wool sweater and pants), warm socks, a change of clothing (just in case) and a lunch or snack. Good hiking shoes are recommended. Sturdy hiking shoes, waterproof jacket and pants can be rented beforehand if you contact us or book online.
