Exploring Ape Cave at Gifford Pinchot National Forest near Cougar, Washington is a easy 2.5-mile hike that leads hikers down into the dark underground lava tube of Ape Cave.
The cave does not have much to see, but it is a unique experience nonetheless. Hiking through a lava tube, especially at this size, is certainly worth seeing once. Including the return hike, this trip is under 3 miles, hence the 2.5-mile total.
After entering the cave, there are signs for "Upper Cave" and "Lower Cave". The Lower Cave is an easy kid-friendly walk that ends after about 3/4-mile. The Upper Cave is just over 1-mile long but there's an exit at the other end so hikers can get back to parking above ground.
The Upper Cave section is still an easy walk but it requires a little bit of climbing, so it may not be suitable for children. Near the end of the Upper Cave is a solidified lava flow, about 8 feet tall, that has some foothold carved into it for climbing.
Permit and Fee
Hikers are required to get a permit to enter Ape Cave. The permit can be purchased at the parking lot.
Hikers will find a decent sized lot at the parking coordinates provided, but this lot can get busy during the Summer.
Hikers will need at least two light sources per person to illuminate enough distance for it to be safe. Consider purchasing headlamps before this trip, otherwise during the Summer, lanterns can be rented at the kiosk near the entrance. Hike at your own risk.
