About Sinks Canyon State Park

Sinks Canyon State Park is a geological wonder in Wyoming, known for the unique phenomenon where a river disappears underground and re-emerges down the canyon.

Wilderness Landscape & Natural Heritage

Located at the base of the Wind River Mountains in Wyoming, Sinks Canyon State Park is a fascinating site where the Middle Fork of the Popo Agie River plunges into a limestone cavern and vanishes, only to reappear in a pool down the canyon. This natural occurrence, known as 'The Sinks', is a highlight of the park. The area encompasses diverse ecosystems, from towering cliffs and lush forests to plains teeming with abundant wildlife, including moose, bighorn sheep, and the rare Wyoming toad. Historically, the region has been important for Native American cultures and later for settlers and explorers venturing into the western frontier. Today, it offers various recreational activities like hiking on the numerous trails, rock climbing on well-known cliffs, fishing in the river, and camping under star-lit skies. Key landmarks include the Rise, where the river resurfaces, and the Sinks itself. The park's scenic beauty and unique features continue to draw nature enthusiasts and outdoor adventurers every year.
