Ape Caves (Upper & Lower)

Distance: 3.5 round trip
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.
Mt. St. Helens from Ape Cave Trail

From the parking lot, follow the Ape Cave trail past the main entrance in route to the Upper Cave entrance. You will travel above ground for about 1.5 miles before reaching the Upper Entrance. There will be plenty of views of Mt St. Helens and its unique (ashy) landscape.
Upper Cave Entrance
At the end of the trail, locate a narrow hole in the ground and jump in! A metal latter will assist you in your descent into the lava tube.  The Upper Cave portion is much more difficult than the Lower portion. Be prepared for 25+ rock piles to maneuver through and a lava wall of 8ft.

Upper Cave

The more difficult, upper portion of the cave, can be skipped if you aren't up for it. However, the challenge is worth it.
Lower Cave Entrance

Once you pass the above entrance, the upper cave ends and the lower cave begins. This portion of the cave is shorter and much easier to navigate.
Arch
Narrowing Cave

Marked by an overhanging arch, the cave begins to gradually narrow until completely ceasing. I would suggest a three point turn at the arch. Crawling on all fours through the narrowing cave can be claustrophobic.  Whichever your decision, the trail has ended! Backtrack to the main entrance and get some fresh air!
