Big Hole River Fly Fishing
The Big Hole River embodies Montana’s freestone fishing at its most authentic—a large, wild river flowing through some of the state’s most pristine wilderness. Rising from small streams and springs in the Upper Big Hole Valley, this legendary water carves through cottonwood-lined banks and braided channels while supporting diverse trout populations and world-famous insect hatches. The Big Hole’s raw beauty and challenging fishing conditions create an atmosphere where every cast connects you to Montana’s untamed fishing heritage.
