Its eminent feature is its thousands of hoodoos and hoodoo rocks, referred to locally as “goblins”, which are formations of mushroom-shaped rock pinnacles, some as high as several meters. The distinct shapes of these rocks come from an erosion-resistant layer of rock atop softer sandstone. Along with Bryce Canyon National Park some 190 miles to the southwest, Goblin Valley State Park is one location with some of the highest occurrences of hoodoos in the world.
The park lies within the San Rafael Desert southeast of the east limb of the San Rafael Swell and north of the Henry Mountains. Utah State Route 24 passes about four miles east of the park. Hanksville lies 12 miles to the south.
Hiking is permitted in the park, which features three marked trails.
