Madison River
Montana’s blue-ribbon trout river and one of the most famous wild-trout fisheries in the world. The upper river between Quake Lake and Ennis — the legendary “50-mile riffle” — runs fast and braided over wild rainbow and brown trout. Waded and floated hard all season; the salmonfly and caddis hatches are events.
