It was an absolutely gorgeous day when we went--70 degrees F with large puffy clouds. I thought it was very pleasant. There wasn't much shade, though, so I think that on a typical Texas day when temps get closer to 100 it would be far too hot to walk in the afternoon. Nice gravel path with trash cans and doggie mutt mitts at the major intersections. I liked the little bat observation deck. We went down to the fenced in cave opening, but it looked like it was blocked with a large rock. I guess there's still enough room for the bats to come and go, though. Startled some does on our way down there. LOTS of cacti to be wary of if you go off trail for any reason (but there really aren't any reasons, unless you're playing the disc golf course).
