Doudy Draw Trail descends from the western edge of the Flatirons Plateau into the draw and north to the Doudy Draw Trailhead. The Spring Brook Loop can be accessed by following the Doudy Draw trail 1 mile past the junction with Flatirons Vista. The Goshawk Ridge Trail and Eldorado Mountain HCA are accessible from Spring Brook Loop.
