Goblin Valley is a small State Park, about 2 miles long and 1 mile wide. In the valley are thousands of amazingly shaped rock figures, most of them no more than two or three meters high, surrounded by a wall of eroded cliffs. The shapes of these rocks result from an erosion-resistant layer of rock atop relatively softer sandstone.

In 1949 the valley was named "Mushroom Valley", because many of the rock figures resemble mushrooms. Later the name was changed into Goblin Valley, which is also a well chosen name because one can easily see an army of gnomes in these hoodoos. Goblin Valley State Park (and Bryce Canyon National Park) contain some of the largest occurrences of hoodoos in the world.

The goblins, like the surface of the valley, all have the same chocolate brown colour. Plants and flowers can hardly survive in this dry, warm environment, so there is no vegetation at all here.
It is also allowed to walk into the valley and wander between the goblins.

Goblin Valley was granted the status of State Park in 1964.
