At 7 p.m., the gate closes off the park road leading into Pima Canyon, near the northeast tip of Phoenix's extraordinary South Mountain Park/Preserve. Cars can't get back in there — but you can. A ranger told us recently that night hikers or bikers are good to go, even after hours. (He added that if police catch you out there past 11 p.m., they may tell you to get out but won't ticket you). We can't tell you where to park for a night adventure in South Mountain — the Pointe neighborhood surrounding the park entrance is private property. However, once there, it's a beautiful, peaceful walk by moonlight — or starlight — that anyone can do. Unlike a desert single-track trail, this hike is easy at night because it begins on a mile-long asphalt road (usually filled with parked cars in the daytime) and continues with another mile or so of pleasant dirt road winding through low hills. At night, we typically stop at the benches near the National Trail trailhead before turning around. True, the place can be spooky after the sun goes down — akin to a stroll down a long, dark alley. It's probably best to take a friend or two. But if you're the type who scoffs at such risk, hiking Pima Canyon at night offers a tantalizing trade of perfect safety for an hour or two of wilderness-inspired bliss. Did we mention it's cooler at night?
