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.

Fall colors are at peak but any time is the right time to drive up into The Sinks or take the entire loop if you are in the area. Note the contrast in vegetation between north facing & south facing sl... more »

We took a drive up to the top of the mountain at sunset. It is steep and winding, and the rock canyon walls are beautiful. more »

Great place to go visit whether you don't have a lot of time or have tons of time. There is plenty of hiking/biking options out here and going to "the sink" and "the rise" is a must do and is only a very short walk for all ages. If you have a quarter, buy some fish food and you can feed the huge fish swimming below at "the rise". Staff is super helpful and friendly at the visitor center and is worth the stop in. You will probably learn a few new things.

Hidden GEM! Right along the river, very scenic! Cheap camping too! Most sites are small and the roads are narrow, so leave your big rigs at home. They should mark the campground roads one way, pretty confusing otherwise.

Beautiful part of Wyoming. We like the hike to the falls from Bruce's Picnic area as well as canning at Frye Lake.

Very interested, the water runs underground for miles , no one knows where it goes, pops up 1/4 mile down the road. Huge 30" + rainbow trout

One of the best state parks in the country for sure. Something here for all visitors; climbing, hiking, swimming, site seeing, (free) camping birding, bouldering, picnics and cookouts and a great visitor center, got to check this place out.
