The Bear Creek to Essex River run in Montana is best suited for experienced rafters due to the challenging Class III and IV rapids. The river offers stunning views of the surrounding mountains and forest, but requires careful navigation around rocks and tight turns. The best time to float this section of water is in late spring or early summer, when water levels are high and the rapids are at their most thrilling. Recommended flow levels range from 800 to 1800 cfs. Rafters should be prepared for the possibility of cold water and strong currents, and should wear appropriate gear and safety equipment.
