About Southwest Colorado
Southwest Colorado features the rugged San Juan Mountains and major rivers like the Animas River (Durango), the San Juan River, the Dolores River, and the Gunnison River (including the Black Canyon).
This is a land of dramatic geology and diverse fisheries. The Gunnison is a Gold Medal giant famous for its Salmonfly hatch. The Animas offers Gold Medal urban fishing, while the San Juan tailwater below Navajo Dam (just across the NM border, but influencing the region) is world-renowned. The Dolores offers challenging catch-and-release fishing for wary trout in a stunning canyon setting.
