We currently offer two lava caving trips, Underworld summer and Underworld winter. Underworld Summer takes place in Thingvellir National Park where we explore Gjabakkahellir cave. On the winter trip we change locations for better access during the harsh winter months; we explore Leidarendi Cave, a magnificent lava tube hidden in the Blue Mountains area. 

To make your adventure even more exciting we offer lava caving combos, in which our Underworld trips are combined with other popular activities like snorkeling, Golden Circle sightseeing, Super Jeep Self Drive and Quad biking (ATV).
