One of Seven Natural Wonders of the World, Grand Canyon is impressive at any time. The best time to visit the Grand Canyon is during spring and autumn when the weather is mostly sunny but not too hot, which is perfect for sightseeing. From March to May, visitors can spot wildflowers in this dry and rocky place. It's also the time to observe baby animals and rare birds like the California Condor. In mid-May, the snow melts in the North Rim area, and it becomes possible to explore this less crowded part or do the Rim to Rim hike. June is also an excellent time to visit the canyon, especially for astronomy fans to join the Grand Canyon Star Party. July and August might be spoiled by visitor crowds and T-storms, but it's when most facilities and trails are open. Autumn is a sweet spot with fewer people and breathtaking sunsets. In winter, you might be lucky to capture the snow-powdered landscapes of the Grand Canyon.
