Jump-off Canyon is a boat takeout located upstream of Highway 20 bridge on the Henrys Fork, approximately 6. 5 miles downstream from Stone Bridge, where the current slows dramatically in the estuary of Aston Reservoir—making it a good option on windy days.

Wade access is available at this access point and nearby locations, though access between points is mostly private property. This takeout serves as an alternative to the Fremont County Boat dock for floaters looking to exit before entering the reservoir.
