NPS Photo Explore the scenic Mullinaw Trail, which runs along the banks of the Canadian River—the longest tributary of the Arkansas River in the United States. Originating in Colorado, the Canadian River flows through New Mexico, Texas, and Oklahoma. The Mullinaw Trail offers excellent opportunities to observe birds, wildlife, and wildflowers. Keep an eye out for large raptors migrating to the cottonwood trees, as well as woodpeckers and cardinals along the trail. Make sure to bring binoculars, a nature journal, and a camera. This trail is particularly stunning during the fall when the cottonwoods transform into a vibrant tapestry of colors.
