Although it follows behind the Grand Canyon as a state attraction, Oak Creek Canyon doesn't skimp on scenery or activity. The beautiful, 16-mile-long geological feature is distinguished by rock formations in shades of red, yellow, and white and by its abundant vegetation and wildlife. Folks come to be mesmerized by the spectacle, to hike on canyon trails, and to fish its fruitful waters (licenses required). Campsites can be found as well, along with picnicking areas.
