Details

The natural phenomenon of Iceland's underground world was created when the surface of the lava flow hardened, leaving fluid lava flowing beneath this hardened surface. Follow your experienced guide as you pick your way along passages, through extraordinary caves, and into the heart of dark grottos.

Please note that even though the caves are wide and high in places and the floor is fairly even, it is advisable to wear hiking boots or good walking shoes suitable for the coarse lava surface. There are no handrails, lights, or any pre-installed tools in or around the caves; however, this tour is suitable for anyone able to walk on coarse surfaces.
