Sinks Canyon State Park is a publicly owned recreation area located in the Wind River Mountains, 6 miles 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 1/4 mile down the canyon in a pool named "the Rise."The exact route of the passage is unknown, and dye tests have shown that the water takes over 2 hours to make its 1/4-mile underground journey. Additionally, more water flows from the Rise than enters the cavern at the Sink. The Crow Indian name of the river, "Popo Agie" (pronounced po-PO-shuh), is taken to mean "gurgling river."GeologyThe Madison Limestone Formation was carved by glacial movement, leaving extensive underground fissures and steep cliff walls. The gradual recession of the ice left glacial moraines along the canyon floor.Activities and amenitiesA visitor's center is located at the Sinks, and an observation deck overlooks the Rise. The park offers hiking trails and facilities for camping, picnicking, rock climbing, and fishing.ImagesUse our Lander journey planning app to add Sinks Canyon State Park and other attractions to your Lander vacation plans.

Very cool stopover. First stop, you get a great view of huge fish and can feed them. Second stop (with visitor's center), you get to see a ton of water just flowing into a deep pool and disappearing. Very pretty. Visitor's center is great for kids.
Cool place to visit. Weird how the river goes underground and then rises later. Also love to watch the huge trout!
Pretty cool place to visit. You can feed fish and hike.
Spent two nights here next to river and it is absolutely beautiful. Park staff are very friendly and helpful and the sounds of the river can not be beat. Great place to hike, bike and watch wildlife!!
Fascinating place where the river disappears underground for 500m then pops back up again. Great scenery and informative visitor center. Well worth a stop
