It's a very accessable park that borders on both residential and wilderness areas, and is right within Tucson city limits.
Eric and I packed our day pack with plenty of water, some apples that had traveled with us from Seattle, a couple Powerbars, and two bags of Kirkland mixed nuts. Also grabbed our freebie map of the park and the important binoculars---in hopes of spying a mountain lion someday.
The temps were in the high 80's, so after we'd wandered among the saguaros, ocatillos, barrel head cacti, and chollas for a while, and hiked up and over a rocky ridge, we took a break in a shady part of the wash at the end of the Rattlesnake Trail. Thinking we might find some petroglyphes on the rock face above us, we scanned it up and down, but only saw several broad natural rusty red stripes running horizontally and an interesting little cave about 30 feet above our heads.
Next, we crossed the paved road that leads to the northern most part of the park, and looked down on a green area, an oasis, with a creek running through it. I led the way and scrambled down a faint trail, and gingerly jumped off a 3' ledge to join a path winding its way along side the gentle stream. It would eventually take us to Sabino Dam, which at different times is barely existent or overflowing, depending on the monsoons and rare rainy periods.

A roadrunner scooting beneath shade trees who was hunting for lizards caught our eye as we started making our way back to the deserty part of the park. There were also several bright blue hummingbirds buzzing overhead, buzzing and warning us to stay away from their extra large nectar bottles.
