Sinks Canyon State Park

Sinks Canyon State Park is a natural preserve in the southern Wind River Mountains where the Middle Fork Popo Agie River cuts through limestone formations creating narrow canyons. The park includes hiking trails, picnic areas, and four year-round heated yurts with electricity for overnight stays.

The site received official status as a Wyoming State Park in 1971, protecting the limestone formations and natural resources for public access. This designation ensures the geological features remain preserved for future visitors to explore and study.

The river's name originates from the Crow language, reflecting the indigenous peoples who inhabited these mountains for generations. You can sense this connection to Native American history through the place names and the landscape itself.

The park offers easily accessible hiking trails of varying difficulty and picnic areas with basic facilities. The heated yurts provide comfortable overnight accommodations and appeal to visitors who want to explore the area without traditional tent camping.

At a spot called The Sinks, the river disappears completely into a limestone cavern and resurfaces about 400 meters downstream at a pool named The Rise. This natural phenomenon draws visitors fascinated by how water shapes rock over time.
