Ape Caves are currently snow-free and accessible with roads suitable for all vehicles. The trail itself is reported in good condition, with no significant bug issues. The lower cave offers an easy walk, though the floor can be uneven, making it suitable for young children. The upper cave presents more of a challenge, involving scrambling over large boulders and a notable 8-foot wall that often requires assistance. Recent reports from September 6 and October 19 highlight families successfully navigating these upper sections with some help. While generally passable, one report from July 22 details significant cave-ins in the upper tube, describing it as life-threatening and suggesting it should be closed or deeply warned against, with no recent reports contradicting this severe warning. Visitors are reminded that food and drink (other than water) are not allowed in the caves.

One report from July 22 describes significant cave-ins in the upper tube, creating a hazardous area with large, pointed shards of stone and requiring navigation over unstable surfaces with potential for serious injury. No subsequent reports since July 22 have directly addressed or contradicted these severe findings, and it is unknown if park officials are aware or have assessed the situation.
The 8-foot wall is frequently mentioned as a significant obstacle in the upper cave. Reports from September 6 and August 1 indicate that while manageable, it is challenging and often requires lifting or assistance, especially for children. One report from August 1 noted virtually no handholds and only a single usable foothold.
The lower cave is described as a very easy walk with a slightly uneven cave floor, suitable for families with young children, including toddlers. It is heavily trafficked and straightforward to navigate. This section offers a cool environment for a hike, particularly on hot days.
Visitors should bring at least one reliable light source per person, with headlamps being highly recommended to keep hands free September 6 and September 6. Warm clothing is advised, as temperatures inside the cave are around 40-50 degrees Fahrenheit September 6 and August 8. Sturdy shoes with good grip are essential due to uneven and rocky terrain.

Our party included 4 adults and 2 children (ages 6 and 7). We did both the lower and the upper caves. The lower is a very easy walk though the cave floor is a bit uneven so just make sure to watch you...

We did the upper portion with our 4 and 7 year old and we all had a great time. The only time I assisted my boys was at the mid point where the 8' wall is. I lifted them up a bit and they scurried up ...
The parking lot is to the right just a few hundred yards beyond the entrance. If you see the dead end road sign, you’ve already gone too far and that dead end road goes for miles and miles. Ask me how...

Dark, Creepy and Cool! This is on my list of "It Seemed Like A Good Idea At The Time" hikes. Most of my hikes end up on this list because although I think I am an intermediate/ expert hiker, I complai...
For anyone considering the upper trail, don’t let the sign describing it as a “difficult walk” lull you into a false sense of security. In my opinion, that description significantly understates what y...
TL;DR - The "Upper tube" of Ape Caves should be closed to human traffic, or at least DEEPLY warned against, because sometime in the last year there have been significant cave-ins.I have good, sturdy, ...
Went on the upper cave trail. Lots of scrambling over slippery/wet boulders, and there was one point where it took two other people helping me in order to pass a quite steep part on rope. If you’re lo...
