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.ImagesAdd Sinks Canyon State Park to your Lander travel itinerary, and discover new vacation ideas by using our Lander vacation generator.

Oh, this place is beautiful! I had no idea that this place existed. My Mom suggested a road trip, and we through around a couple ideas, then she mentioned Sinks Canyon. She hadn't been there for years, and my niece and I had never been. We got a late start, so we couldn't check everything out. I will definitely go back for another adventure.
A beautiful spot on the river. We slept well with the white noise from the river. Enjoyed the hiking and wildlife. The sink part is interesting. Good visitors center with information on the area.
Beautiful setting along the Pope Agie River. The Sinks and The Rise are a very interesting phenomenon where the river plunges into a cave and surfaces 1/4-mile away.
