Hiking, biking, fishing, picnicking -- even golfing -- among the otherworldly buttes, crags and palm-shaded water holes of one of the few significant parcels of lowland Sonoran Desert remaining in the urban Valley. West-facing Hole-in-the-Rock, a Hohokam archaeoastronomy site, is famed for its sunset views; Desert Botanical Garden and the Phoenix Zoo are situated within the park.
