The park features uniquely pink-hued sand dunes located beside red sandstone cliffs.
The dunes are formed from the erosion of pink-colored Navajo Sandstone surrounding the park.
High winds passing through the notch between the Moquith and Moccasin Mountains pick up loose sand particles and then drop them onto the dunes as a result of the Venturi effect.
[2] The park allows camping, hiking, off-road vehicle driving, and photography.
[5][6] The park also contains most of the remaining individuals of the rare plant known as Welsh's milkweed (Asclepias welshii), a federally listed threatened species.
