We stopped & had lunch at the beautiful pull off before heading to Ape Caves - McClellan Viewpoint
You need to make reservations ahead of time to visit Ape Caves. It also costs $5 to park unless to you certain passes. Details on the website.
We had headlamps & flashlights. We did the easier 3/4 mile hike. I read the moderate involves a lot more effort & we had already hiked some. The easier hike was a great experience.
