This Meetup is past


This hike has been cancelled.

I am cancelling the hike due to another group of 40, going up to the Ape Cave on a "party bus for outdoor drinking activities," to quote the Meet Up announcement. I'm sorry for the inconvenience, but I don't think it would be a good idea to go up there when another large group is planning on doing the same hike at the same time. If you are interested in their arrangements please go to the following link:

Route Description: Tired of hiking in the blistering sunshine? For a change of pace, join us on this “indoor hike” in the dark of the Ape Cave in the Mt. St. Helens National Volcanic Monument.

This is the third longest lava tube in North America. We will be doing the more rugged upper section of the cave, where we will traverse 10 major rock falls, scramble up an 8’ foot headwall, and pass through a “squeeze” slot. Then we will pass the skylight and soon come to the metal ladder that leads out of the cave. Come prepared for a chilly day, it’s a steady 42 degrees in the cave. The trail back to the parking lot is a quick 1.2 miles, so we won’t get too sunburned.
