Fodor's Expert Review Shafer Trail
This road was probably first established by ancient Native Americans, but in the early 1900s ranchers used it to drive cattle into the canyon. Originally narrow and rugged, it was upgraded during the uranium boom, when miners hauled ore by truck from the canyon floor. Check out the road's winding route down canyon walls from Shafer Canyon Overlook before you drive it to see why it's mostly used by daring four-wheelers and energetic mountain bikers. Off the main road, less than 1 mile from the park entrance, it descends 1,400 feet to the White Rim. Check with the visitor center about road conditions before driving the Shafer Trail. It's often impassable after rains or snow.
