Sinks Canyon is a state park in Wyoming, managed by State Park and Recreation, and it serves as a climbing area within its own boundaries. The park sits in the state's central region, and its climbing draws climbers to the Scud Wall and Killer Cave areas, both about 0.1 mile away. The climbing here is all sport, with 12 routes spread across a range from 5.1 to 5.14a. Among them are Beehive Boulder -- South Face Direct at 5.1, Campfire Fodder at 5.7, and Monkey Gone To Heaven at 5.14a. The median grade is 5.8, so the area offers a mix of easier and more challenging options. Summer is the most comfortable time to visit. Typical averages from a nearby weather station in Lander run to highs around 88°F in July, with lows near 55°F. That station sits about 1,370 feet lower than the canyon, so temperatures at the climbing areas run cooler. Winter is cold, with January highs around 33°F and lows near 10°F. The Popo Agie Nature Trail and Sinks Canyon Campground are both about 0.4 mile away, and Lower Brewer's Trail is about 0.5 mile off. For paddling, the Middle Popo Agie River is about 3.3 miles away.
