From Phoenix AZ, take Hwy 17 to flagstaff. Take Hwy 40 heading West to just before Williams. Turn right on Hwy 64 and drive into the park. The road to Hermit's Rest is closed to regular traffic most of the year, so take the free shuttle bus, which stops at all the viewing areas including Pima Point, the last stop before Hermit's rest.
If going to the park in the fall / winter, it's a good idea to pack for cold rainy weather, not only for yourself, but also for your camera.
Heading toward Hermit's Rest along the south rim of the Grand Canyon, I hopped off the shuttle at Pima Point viewing area to set up my tripod and camera in order to capture the November storms moving through the area. That silver ribbon of water is the Colorado River.
