This is a very tight and claustrophobic adventure. It is not for the faint of heart. This is an intricate maze with multiple levels. There is nothing safe about it and is possible to get lost or very injured inside. The caves go about 30 feet underground.
Make sure you mark your way in so you can find your way out again. I would believe that this trip is not for your average person. You definitely want to go with a few other people, bring headlamps and let others know where you're going in case something goes wrong.
Personal Experience: Holy crap, what an adventure! I have been out here many times and foolishly never realized that the REAL adventure and REAL caves were further down the hill! The first talus cave is fun, sure, but NOTHING compared to what lays below. Please do not go out here or bring friends unless your whole group is experienced. The place could get shut down for everyone if someone gets injured.
I have not explored the bottom of the canyon yet but have large desires to do so. I have a hunch many more adventure await in this region.
There is a whole world in there!
The view is stunning!
