I went there on an overcast (thank god!), cool (for Tucson) day and hiked up to the Romero Pools. That was a challenging hike--at least five miles return, and lots of steep up and down. The perfect hiking weather brought quite a crowd. The parking lot was full, but it's OK to park along the road. The trail was busy. Wild flowers were abundant and vivid, vistas are spectacular. The Romero Pools are deep and busy with happy folks cooling their feet and jumping into the deeper parts.
You don't have to hike to the Romero Pools. There are other trails and lots of activities, including birding. The day I went, there was an exhibit of desert wildlife, including the poisonous varieties--most notably some big old Gila monsters. Customers were encouraged to handle some of the harmless animals. Great for the kids.
