The river run is best tackled in late spring or early summer when water levels are at their highest, with a recommended flow of 1,000-2,000 cfs. Obstacles to be aware of include the "Notch" rapid, a narrow chute with a large boulder in the middle, as well as "Pinball," a series of technical rapids with multiple boulders and tight turns. Overall, the Box Canyon river run is recommended for experienced rafters and kayakers looking for a thrilling adventure.
