Beaverhead River High Bridge Fishing Access is a moderately trafficked point-to-point trail located near Dillon, Montana that features a river and is good for all skill levels. The trail is primarily used for hiking, fishing, and fly fishing and is best used from May until September.
My favorite BIG TROUT river in MT. Ridiculously huge fish everywhere. Use light tippets - 6X and small nymphs in the day then move to big streamers and stout tippets - 15lbs in evening or early. You wil be amazed.
