Sinks Canyon Campground sits at 6,893 feet along the Popo Agie River in Shoshone National Forest, where the river famously disappears into limestone caves before resurfacing downstream. The 14-site campground runs $15-20 per night, first-come first-served, with sites spaced far enough apart that reviews describe it as quiet and secluded. It's a base camp for climbing the canyon's BLM routes, hiking into Popo Agie Wilderness, and fishing the river from late June through August.
The campground provides options for tent camping, RV camping within size restrictions, and possibly group camping. There are no mentions of cabin rentals or glamping options.
Weather and SeasonsSummer delivers the most reliable camping window. Expect daytime highs around 70-85°F and nights dropping into the 40s-50s°F. Trails clear of snow, the climbing routes stay accessible, and fishing peaks from late June through August. Spring runoff feeds the falls and river, making them most dramatic but also loudest. Weekends fill up at this small campground, so weekdays or the shoulder ends of summer offer better odds at snagging a site. Winter sits around 30°F and buries the canyon in snow, limiting access but offering solitude if you can handle the cold.
ElevationPerched at a classic mountain elevation, the campground offers that perfect sweet spot where the air is refreshingly thin but not breathtaking, where alpine meadows meet rugged canyon terrain. This mountainous setting provides cooler temperatures, stunning vistas, and that distinctive high-country atmosphere that makes every sunrise feel like a celebration.
Natural Features and SceneryThe campground's defining feature is the Popo Agie River, which rushes through camp loud enough that some reviews cite the constant water noise as both lullaby and complaint. Limestone formations shape the canyon walls, part of a landscape sculpted over millions of years by water carving through rock. The river's disappearing act into underground caverns happens nearby, then reappears a quarter-mile downstream at a spot called The Rise. Canyon walls provide the exposed rock that draws climbers. Upstream, Popo Agie Falls runs scenic during spring runoff and early summer, while trails extend into the Popo Agie Wilderness backcountry.
Geological RegionWelcome to the geological wonderland of Sinks Canyon, where limestone caves, ancient rock formations, and the famous disappearing river create a landscape unlike anywhere else. This unique terrain, sculpted by millions of years of water and wind, offers a front-row seat to Earth's creative forces. The nearby Popo Agie Wilderness extends this geological story into pristine backcountry, where dramatic peaks and hidden valleys await discovery. For rock climbers, the exposed canyon walls and surrounding formations provide world-class routes carved by nature's patient hand.
