Marias River National Wildlife Refuge provides vital habitat for migratory birds and a variety of wildlife along the Marias River in northwestern Montana, offering excellent opportunities for wildlife viewing and photography.
Marias River National Wildlife Refuge is located in northwestern Montana, encompassing riparian habitats, wetlands, and floodplain forests along the Marias River, a tributary of the Missouri River. Established in 1941, the refuge spans critical lands that support migratory waterfowl, shorebirds, and numerous other species of wildlife. The refuge's landscape includes cottonwood galleries, wet meadows, and shallow ponds, providing ideal breeding and nesting grounds. Ecologically, it is an important stopover for species traveling along the Pacific and Central flyways. Visitors are drawn primarily for birdwatching with over 150 species recorded, along with opportunities for quiet nature walks and photography. The refuge features relatively undeveloped terrain with a few short trails and observation points that highlight the riverine ecosystem. It serves as an educational site promoting wetland and wildlife conservation. Its remote location near the town of Shelby provides a peaceful setting for those interested in Montana’s natural heritage and waterfowl management. Hunting is permitted with special regulations during certain seasons, supporting sustainable use. The refuge plays a role in preserving the ecological integrity of the Marias River corridor amid ongoing regional development. This protected area is one of the few natural green spaces in this part of Montana, offering visitors chances to experience wildlife in an unspoiled setting.
