A self-guided brochure is available at the trailhead. It describes the plant life and geology of the dunes. Much of the trail is through loose sand and is strenuous.
The Cottonwood trail takes you through the perched dunes above the Dune Climb and provides access to a variety of dune plants and wildflowers.
The Cottonwood Trail provides beautiful views of Glen Lake and the Dune Climb.
