The visitor center lent us an additional lantern and pointed us to Sentinal cave which has an entrance as well as an exit. The ceiling is high and the path is wide, bit we had to pick our way carefully through the rocks.
The second cave we chose was called Skull Cave because many skeletons had been found here. It was also broad and high, but very deep. We descended 74 steps within the cave in addition to 59 steps just to reach the entrance. Deep in the cave ice had formed on the floor. In the winter the heavy cold air drops into the cave, freezing water in the bottom.
As we left we stopped at Devil's Homestead, a huge, impressive flow of black, volcanic rock which is barren as a moonscape.
