Hike downstream from where the W. of Rocks trail crosses the creek. It's dicey. Wait until Mikehikes gets back from his Diamond Down river trip and ask him. I don't think I have been all the way down to all the pools, only to some of them. I've heard that the further you go the harder it gets, and sometimes you really have to go way up along the sides, the higher up the better, in order to get below some of the waterfalls. One old-but-good book with this hike in it is Trail Guide to the Santa Catalina Mountains by Pete Cowgill and Eber Glendening. But if the fire went through there it will be different now than when the book was written.
I have hiked way down Upper Sabino, too, from Marshall Gulch on down. That was really nice, too. Before the fire, of course.
