Rainbow Trout
The Bitterroot River near Darby, Montana, is a rainbow trout paradise, renowned for its clear, cold waters and stunning scenery. What sets this fishery apart is the abundant insect life, making it a prime destination for fly fishing enthusiasts. The best time to target rainbows here is from late spring through fall. The Skwala stonefly hatch in late April and May kicks things off, followed by prolific mayfly and caddis hatches throughout the summer. Fall brings cooler temperatures and spawning activity, making for aggressive takes. For access, consider the numerous fishing access sites (FAS) along Highway 93 that parallels the river. Be aware of changing river conditions, especially during spring runoff, which can make wading difficult. A local tip: try nymphing with stonefly patterns in the deeper runs during the Skwala hatch. The rainbows in the Bitterroot are known for their vibrant colors and fight, making for a memorable angling experience.
