The Essex to Moccasin Creek river run in Montana is a scenic and enjoyable float trip. It is a Class I-II section with occasional Class III rapids. The best time to float is in late spring or early summer when the CFS is around 1,500-2,500. There are a few obstacles such as log jams and shallow sections, but they are easily navigable. The river run is suitable for beginner to intermediate paddlers and offers stunning views of the surrounding wilderness. Overall, it is a great choice for a relaxing day on the water.
