Ape Cave

Descrição do trilho

A 4.1 km loop at Mount St. Helens through Ape Cave, one of the longest lava tubes in North America: in from the lower entrance through the upper passage to the upper entrance, then back on the surface trail through the forest. The upper passage means climbing over rock piles and up a small lava fall in the dark. Bring two lights each and warm clothes, as the cave stays cold all year.
