I really want to highlight that you should keep hiking past the "sky light" with the super sketchy old ropes. This is not the exit from the upper tube. I used the sky light today, not knowing there was a different exit. I ended up...More

We went to the Ape Caves on April 13 2019. Outside there was still small amounts of snow but the mile walk to the cave entrance was clear. The upper parking lot is permanently closed, so be ready for this walk from lower parking. It...More

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

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

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.
