About - Sinks Canyon


Sinks Canyon State Park is located in west central Wyoming just south Of Lander, WY. The park is situated in the Wind River Mountains on the middle fork of the Popo Agie River. The site is named after a distinct geologic phenomena in which the Popo Agie river disappears into a Limestone cavern and reappears a ¼ mile down canyon in a placid pool filled with 8 - 12 lb. rainbow trout. The site has a variety of natural habitats which creates diversity of flora and fauna. The canyon provides a variety of recreational opportunities including nature studies, photography, camping, fishing, hiking, world class rock climbing and access to miles of mountain bike trails.


Sinks Canyon has served as a corridor from the river valley below to the high peaks of the Wind River Mountains. Humans, who were attracted by the rich natural resources, arrived in the canyon approximately 9000 years ago.

Ice, wind and water have carved the U shaped valley and provided access for flora, fauna and humans to utilize the rich natural resources found in the canyon and the montane/alpine region above.
