The road was plowed up to Trail of Two Forests Trailhead. Which meant to get to the Ape Caves you had to travel on foot. Some people knew this and had come prepared with snowshoes. Some did not, like us. We were dressed in full...More

We took the caves from the near entrance out and walked the above ground trail out. We brought our dogs but learned upon arrival they are not allowed in the caves and for good reason. The terrain is difficult, the walk seems long, and it...More

I have been to the Ape Caves 3 times now. Once down the lower side and twice up the longer way. I am from California and I have already commented to a few people that I love the accessibility of the cave. While a metal...More

Must bring strong headlamp (or flashlight) and proper tennis shoes or hiking boots. It's an underground lave tube so it gets pitch dark and slippery at some points due to the snow and water. It can be a short or long hike. If it's the...More

This place is a great adventurous excursion for the family. I took my wife, 14 year old daughter, and 11 year old son. It has just the right amount of adventure, and a bit of scare to keep the kids very much into the entire...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

No, but the road to Windy Cave offers a partial view, even if it’s only open part of the way. The best view was from the Oregon side, going up the hill from the river, but that’s a bit of a drive from Ape Cave.

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.
