Gjábakkahellir
A beautiful lava tube in the National Park Thingvellir
Gjábakkahellir (aka ´Little Girl´s Cave´) is a 360 meter long lava tube located in the National park Thingvellir.
It is easily accessible as there is only 50 meter walk from the road to the opening of the cave and once inside it has all the typical features of a lava tube, the lava falls and shark tooth stalactites being particularly impressive.
The cave floor is covered with large rocks that have fallen from the cave ceiling in the cooling phase of lava field and participants will in places have to use both hands and feet to navigate through the rough terrain.
The cave was first discovered in 1907 when workers were preparing a road between Thingvellir and Geysir for the King of Denmark which at that time ruled Iceland as a colony.
Since then more than a dozen of caves have been discovered in the area and one of those appears just as a hole into the ground within a 20 meter distance from Gjábakkahellir.
