Field briefing
Sinks Canyon State Park changes fast with season and elevation.
Before you go
There is no day-use fee, so the planning moves are simple: reserve a campsite in summer, see the Sinks and the Rise first, and decide whether you want a short interpretive walk, a real canyon-wall hike, or a climbing day.
The landmarks worth the trip. Tap any photo to enlarge.
Weather, crowds, and what the season changes about the trip.
Cool and variable, with high water in the Popo Agie and snow lingering on shaded trails and the upper canyon road.
Pack Waterproof footwear, layers, and traction for late snow on north-facing trails.
Warm days, cool canyon mornings, and the reliable window for hiking and climbing.
Pack Sun protection, water, and bug repellent near the river.
Crisp days, cottonwood color, and the best climbing temperatures before snow returns.
Pack Warm layer, headlamp for shorter days, and a wind shell for the canyon.
Cold and quiet, with reduced services and first-come off-season camping.
Pack Insulation, traction, and a plan for limited facilities.
The Sinks and the Rise
The signature sight: the Popo Agie River pours into a limestone cave at the Sinks and reappears a quarter mile downstream at the Rise, where large trout hold in the pool.
North Slope Trail
A climbing trail up the canyon's forested north wall for hikers who want elevation and overlooks above the river.
Canyon climbing crags
Sinks Canyon is a regional sport and trad climbing destination, with crags reachable from the road and short approach trails.
Keep one flexible slot in the day, because weather, parking, and energy usually decide more than the map does. For one day in Sinks Canyon State Park, make The Sinks and the Rise the non-negotiable, add North Slope Trail only if the first stop runs clean, and keep Canyon climbing crags as the flexible finish.
Turn Sinks Canyon's conditions into water, pack, and sleep-system decisions.

Camp inside the park at Popo Agie Campground if you want to be in the canyon at first light, or use the adjacent Sinks Canyon Campground in Shoshone National Forest as an alternative. Lander, about six miles down the canyon, has hotels, food, fuel, and gear when camping is full or the off-season closes services.
Camping reservations
Popo Agie Campground is the in-park option, reservable in the summer season and first-come in the shoulder months. The park also offers yurts for campers who want a roof.

Getting there
Car strategy
Sinks Canyon sits about six miles southwest of Lander on State Highway 131, which climbs into the canyon and continues up the gravel Loop Road toward the high country in summer.
Car strategy
Most visitors drive from Lander, then either turn the visit into a short interpretive stop or continue up the canyon for hiking and climbing.
Pair this with lodging: the simplest base is the one that removes a real morning problem, not just the one nearest the map pin.
The Popo Agie River flows into a cave in the canyon's limestone at a spot called the Sinks, travels underground, and reappears a quarter mile downstream in a calm pool called the Rise. The water takes longer to resurface than you would expect, and more water comes out at the Rise than goes into the Sinks.
No. Wyoming State Parks does not charge a day-use fee at Sinks Canyon. Camping fees apply if you stay overnight at Popo Agie Campground.
Yes. Popo Agie Campground inside the park offers tent, RV, and yurt options, reservable in the summer season and first-come off-season. The adjacent Shoshone National Forest campground is an alternative.
