Set foot in the beautifully preserved 364-meter long Gjábakkahellir lava tube, on this exciting caving tour at the heart of Thingvellir National Park. Observe the remains of volcanic activity dating back to 9.000 years, that left behind vibrant red rock formations and home to ice sculptures of all shapes during the winter. In this hidden world, no footpaths or installed lights, making it a pristine place of sheer beauty. A relatively gentle descent into the depths suitable for the whole family. Available all year round.
