The Bull River is a clear, cold mountain river that flows through the East Kootenay and eventually joins the Kootenay River just south of Cranbrook. Water flows into this rover from the Rocky Mountains near the Bull River Pass. It winds through forests, valleys, wetlands, and gravel bars, creating habitat for wildlife and fish, including bull trout and other native species. The river is well known for its fly fishing, with long stretches of accessible shore teeming with strong, healthy trout.
