To reach this geological marvel, take exit 21 off I-5 and
head east on highway 503. Remain on course as 503 merges to Lewis River Rd and
again to Rd 90. Take a left on NF-83 and another left on NF-8303. There will be
plenty of signs to point you in the right direction.
The Ape Caves of Gifford Pinchot National Forest is one of
the most unique features created by the 1980 eruption of Mt. St. Helens. These remarkable
caves were hollowed out by flowing lava forcing its way through rock and solid
earth.
Make sure and Suit Up! It will be cold underground. Bring long
sleeves, headlamps, and gloves. Emphasis on the gloves! Not only will gloves
protect you from the cold, but they will shield you from the bat do-do caked on
the cave walls.
