– The park features a geologic phenomenon, in which the Popo Agie River vanishes into a large cavern (the Sinks) but reappears in a trout-filled pool. A visitor center features wildlife exhibits, viewing sites, and interpretive signs. The park contains hiking trails, camping picnicking sites, rock climbing, and fishing.
Sinks Canyon State Park is a public recreation and nature preservation area located in the Wind River Range, six miles (9.7 km) southwest of Lander, Wyoming, on Wyoming Highway 131. The state park is named for a portion of the Middle Fork of the Popo Agie River where it flows into an underground limestone cavern, named "the Sinks," and emerges a quarter-mile down the canyon in a pool named "the Rise." The park is managed by the Wyoming Division of State Parks and Historic Sites.
