Head here for the widest canyon views and a clear look at the Colorado River's Unkar Delta. Most crowds stick to Mather Point, so you actually get some breathing room. Sunset is the move—the red rocks glow as the light hits the Supergroup layers. Plan for 45 minutes or book a sunset rim tour to skip the parking headache. If you're an early bird, morning tours catch the light hitting the inner gorge perfectly.
