A popular stop on the south edge of Mt. St. Helens national monument, it has a limited parking lot (fee) even on non-holiday weekends in May. There are limited facilities here, and bring an extra layer of clothes, a flashlight, and good walking shoes for...More

Ape Caves is a tucked away treasure. It is definitely a special place to the locals and I hope they can keep it that way. Take plenty of lighting, light sides, good waterproof shoes, warm layers, and a good head lamp. The Upper Caves is...More

I won't beat you over the head with what a geological, scientific wonder this truly is. The experience of being underground in the dark, echoing, massive, mile plus underground cave system, will speak for itself. The stalactites and walls drip. A rain jacket is a...More

Lave tubes and no apes... Great story about why it’s named ape caves. Kinda spooky but way cool. Two lava tubes 3/4mile and 1.5miles. Still and quiet. Damp, moist but not clammy. Cool that you get to walk through them on your own without guides...More

This was amazing. We completed the longer, more challenging portion of the tubes and we are thrilled that we did! We would have been in rough shape without our supportive shoes, headlamps, and gloves. Gloves aren't just necessary for warmth. You'll use your hands for...More

We stopped by Apes Caves on our drive back from Portland to Seattle. From the I5 exit, it's about an additional 1hr to the location. It's a windy path and it's 1 lane each way so be prepared for potential slow drives depending on who/what...More

I went to the Ape Cave in August of 2018 on a family outing. The bathrooms are just stinky outhouses, and the visitor center has no electricity and sells room temperature water. They also rent propane powered lanterns which was worth the $6 since there...More

If you love geology, this is the place to go. I did not attempt the more difficult upper cave given the degree of difficulty navigating that part of the cave. The lower part, although easier still takes a good amount of precaution. It is, of...More

Trail of two forests (cool for kids) and Lava canyon (a little tricky for a novice kid hiker) are nearby, we did them. Not much lodging nearby though.
