A. The Grand Canyon really is incredible, each and every day throughout the year. As the sun moves through the sky, the light changes throughout the day at the canyon, so the colors and vistas are ever-changing. Some visitors enjoy the early morning light, while others prefer the colors of evening and sunset. Keep in mind that spring and summer are peak times at Grand Canyon National Park and the business seasons. Fall colors are stunning at the canyon, and winter is quiet and snowy.
