The North Branch of the Westfield River rises in Windsor in the Hoosac Mountains and flows southeast to Cummington, then south to meet the Westfield River in Huntington. This section begins at an old iron bridge on MA 9 and has continuous Class II rapids, with a Class III rapid in every turn. Once the river turns south it is very isolated and beautiful in a wild valley that has been protected by The Nature Conservancy. Two beautiful waterfalls are included in the scenery on this route. Take-out is just above the MA 143 bridge.
