Explore a chilly, pitch-black lava tube over two miles long. A short, paved, accessible trail beneath towering trees leads to a stairwell into the cave. The ¾ mile, one-way lower cave route is relatively easy and family friendly. For the more adventurous, the 1.5 mile upper cave route leads to a climb up an eight foot rock wall and scramble over rock piles, then an exit and a 1.5 mile above ground hike back to the parking lot.
Help protect Ape Cave. Please do not touch cave walls or ceiling. Touching kills cave slime, a basis for the food chain of tiny creatures that live there. Help protect our bats and caves from White Nose Syndrome. Practice Leave No Trace principles by packing out all that you bring with you.
5 dollars fee for parking. Bring a FLASHLIGHT.
