O'Conner Cutoff is a short, easy mountain biking route in Hells Gate State Park, Washington, managed by State Park and Recreation. The trail is an out-and-back that starts and ends at nearly the same elevation, with a total climb of about 43 feet, and covers less than half a mile. The route is front-loaded, with the steepest section, about 7%, coming early. The high point is 854 feet, and the trail returns to nearly the same low of 787 feet. Dogs are allowed. For comfortable weather, late spring and early fall are the best bets. Typical averages from a nearby weather station in Lewiston, Idaho, show May highs around 72°F and September highs around 79°F. July and August average highs near 90°F, and temperatures run cooler at the park's elevation than at the station. Winchester is just 0.2 miles away, and Endurance is about half a mile off. Climbers can head to Hells Gate, roughly 1.5 miles away, and paddlers will find Asotin Creek about 6.4 miles from the trail.
