Fantasy Canyon, Sandstone canyon in Uintah County, United States.

Fantasy Canyon is a sandstone canyon in Uintah County shaped by wind and water over countless years into unusual rock formations. The eroded structures display varied colors and textures that create an otherworldly landscape within a small area.

Earl Douglass, an explorer and paleontologist, first documented the site and recorded it as "The Devil's Playground" and "Hades Pit"; he published photographs of it in The Columbian Magazine in 1909. The quartzose sandstones were deposited 38 to 50 million years ago along the east shore of Lake Uinta. The "teapot formation" collapsed in 2006.

Some formations were named for what they resemble, such as bleached coral, gargoyles and stalagmites; the "teapot formation" collapsed in 2006. Because the shapes are so fragile, the site is called "Nature's China Shop".

A loop trail winds through the canyon allowing visitors to walk among the rock formations and observe them from multiple angles. The path is short and manageable for most people, though sturdy footwear is recommended due to uneven and rocky ground.

Black bands of magnetite run through the sandstone structures along the trail and create detectable magnetic properties. This unusual geological feature allows visitors to witness how certain minerals can affect metal objects.
