I've ridden down there a few times, fun trails, lots of rock!! Surprise, surprise.
Park at the north end, Peart TH, Take Ridge all the way south, that's my favorite trail there, then take Seriously Phil? over to East Phrickin' Butte, to Air Evac back on the Butte to Descent. Then Three Chihuahuas. From there you have some choices on how you want to return. If you really enjoyed Ridge, head back up via Max Hear Rate, then down Primordial. Then OG Connector to Infinity Connector. If you want more zig-zagging, take North Loop, else stay on Penny Lane. That should give you a solid sampling of the riding. It's often overlooked, but it's worth a stop IMO.
This is an older post from my first time there, but you'll get an idea of what the trails look like: Casa Grande
