A paved road runs 3.8 miles into the canyon, crossing Sabino Creek 9 times. The only vehicles allowed on this road are Shuttles and Park Service trucks.
So to get to the end, you either walk or ride the shuttle.
Nomadic Native Americans from the Clovis culture, about 12, 500 years ago, used the canyon to hunt and fish. Later, the Cochise, Hohokam, Pima and Tohono O'odham people made the canyon home.
