It's my personal opinion that one of the most memorable times to see and experience the Grand Canyon is during the winter. The sun is lower in the sky, and the golden light lasts long. There are fewer visitors, and if you're up for taking some short walks, it's possible to feel like you almost have the park to yourself.
Things get magical after a winter storm. The texture of fresh snow reveals every detail that may otherwise be easily missed. As the storm clears from the canyon, clouds often hang onto the temples and buttes below the rim. Just as you think that the show is over, the canyon begins to fill with clouds again, and the view vanishes. But, if you're patient, the view will return, and when it does, it's almost as if Mother Nature herself has pulled the curtains back to reveal her most incredible creation.
