1. Havasu Falls: Grand Canyon, Arizona
Those who brave the Arizona heat to visit Havasu Falls are rewarded with refreshing natural swimming pools. Year-round water temperatures stay near a comfortable 70 degrees Fahrenheit.The falls are at the bottom of Havasu Canyon on the Havasupai Indian Reservation adjacent to Grand Canyon National Park. Havasupai means “people of the blue-green waters,” and the name doesn’t disappoint when it comes to the aquamarine pools at the base of the falls.
The village and falls are only accessible by hiking or horseback. It’s a 10-mile trip from the trailhead to the falls, which are about two miles beyond Supai Village. Hiking conditions are excellent in the earlier spring and later fall, with moderate temperatures.
The area that includes the waterfall is managed by the tribe, which limits the number of visitors. One of the most beautiful and popular spots in the area, reservations are recommended.
