Known as “the longest art gallery in the world,” Nine Mile Canyon offers a 35-mile scenic drive through one of the most impressive collections of ancient rock art and petroglyphs created by Native American cultures. Take a hike along trails like Petroglyph Trail, Whiskers Trail, Dry Wash Trail, and Daddy Canyon Trail to explore this outdoor museum. The canyon is free to visit, open year-round, and accessible by standard car (though caution is advised after heavy rain due to muddy conditions). Just 20 minutes away, it’s a must-see historical and cultural treasure.
