If you’re looking for some climbing, some slime and some Bigfoot lore, the Ape Cave might be the sweet spot.

The pitch-black cave provides a trek into where lava pulsated some 2,000 years ago. When you descend into the darkness, take the “upper cave” path for a longer journey (about a mile and a half), which demands a bit of scrambling. 

Located within the scenic Gifford Pinchot National Forest, Lewis River Falls is a popular destination known for its series of beautiful waterfalls, clear pools, and lush forest surroundings.
