The above ground Ape Cave Trail #239 provides an easy return route, except during the winter season, to the main entrance and Apes’ Headquarters, after hiking the upper cave route. Today the cave is a popular visitor attraction, with many thousands of visitors annually.
At a Glance
12/13/2013: Snow. Perfect moderated snowshoe adventure and caving opportunity starting from Trail of Two Forests.
Pets, smoking, fireworks, and food are prohibited in the cave.
Please leave pets at home, hot summer tempatures can be deadly for pets left in cars.
Note: To protect big game habitat, Forest Road 8303 is closed to motorized use during the winter months. Plan to park at the Trail of Two Forests Trailhead and hike or snowshoe the 1 mile to the cave in winter.
The lower cave is the more popular route with its fairly level, mudflow-covered floor. Highlights include “railroad tracks” and the "meatball." Allow at least an hour to complete the 1.6-mile round trip.
The upper cave travels over large rock piles and requires scaling of an 8-foot lava fall. Two-thirds of the way up you will pass beneath The Skylight, an opening to the surface. Do not try to climb out; this is NOT an exit. The upper exit is only 0.25 mile ahead. The upper cave is not recommended for small children.
Allow 2.5 hours for travel through the upper cave to Ape Cave Trail #239. The above ground Ape Cave Trail #239 provides an easy return route to the main entrance and Apes’ Headquarters.
