Ape Caves
Ape Caves is a fun, short,
but difficult hike. Ape Caves
is a lava tube. The hike is
only about 2.5 miles long but
is difficult and dangerous.
You will have to hike up and
down large piles of rocks. At
one point there is about an 8
foot wall to climb. It is always
cool in the cave. Notice the
clothes I am wearing. I did
this hike in the middle of
summer. It is also dark. Bring
a good flashlight, a back up,
and extra batteries. I also
suggest either bringing or
renting a lantern. I rented a
lantern and it was worth it.
You see much better than
with just a flash light.

This hike is
dangerous. Please
use caution.
