Starting in Roxborough State Park, this hike takes you southeast past the old Sundance Ranch. Nelson Ranch Open Space, situated between the hogback and the foothills, provides habitat protection for foxes, elk, bears, coyotes, spotted towhees, migratory birds, and, of course, swallowtail butterflies. The butterfly shape of the Swallowtail Trail winds around a towering red rock of the Fountain Formation, up and over rimrock, passing by ponderosa pine, Douglas fir, oakbrush, smooth sumac, hawthorn, chokecherry, and wild plum, with a touch of prairie full of rabbitbrush for good measure.
