Sinks Canyon State Park
RV Guide


At the foothills of southern Wind River Mountains in west-central Wyoming lies Sinks Canyon State Park dominating its eastern slopes. At an elevation of 6,112 feet, the park encompasses 600 acres of spectacular views of the area, gorgeous mountain scenery, dramatic views of rocks, and rushing rivers. The park is endowed with many recreational outdoor activities to keep you busy and enjoy your RV vacation. Within the park are scenic hiking trails, a visitors’ center, and amazing rock climbing opportunities.

However, the single most coveted activity is viewing the unique geological formations in the park, known as "The Sinks" and "The Rise." The Sinks is a peculiar geology where the Popo Agie River mysteriously disappears into a mountain cave. The water reemerges a quarter mile downstream into a calm pool called The Rise. There are multiple overlooks where you can watch this vanishing river. Although the exact path followed by the water is unknown, researchers have found out the quantity of water exiting at The Rise is more than the amount entering at The Sinks. With a paved trail connecting The Sinks and The Rise, the hike down has the most rewarding views of the canyon riparian ecosystem.

While driving your motorhome to your campsite, you will note that the park sits on different habitats, each with its unique vegetation. On the base of the southern slopes, the park is characterized by semi-arid vegetation including sagebrush, while the southern slopes bordering the Shoshone National Forest are covered with giant alpines, pine and fir trees. With 24 sites spread across Sinks Canyon State Park campgrounds, RV campers will no doubt love the ambiance of the park.
