History

320 Guest Ranch traces its roots to 1898, when Sam Wilson homesteaded 160 acres along the Gallatin River. In 1900, his father Clinton added adjacent land, creating the ‘Buffalo Horn Resort.’ Dr. Caroline McGill purchased the ranch in 1936, becoming its transformative force. A pioneer in medicine and conservation, she brought electricity to the ranch in 1938 using a Cadillac engine—decades before power lines reached the area. Her legacy endures through the ‘Christmas Cabin,’ historic buildings, and the Museum of the Rockies’ exhibits on her life. The ranch expanded from 20 to over 200 guests under subsequent owners, preserving its Western charm.

Offerings

The ranch offers log cabins with modern comforts, dining at McGill’s Restaurant (known for hearty Montana cuisine), and activities like horseback riding, fly fishing, hiking, and sleigh rides. Fly fishing casting lessons are available on a stocked pond, with equipment rentals for guests. The original Wilson homestead cabin now serves as the saloon, while Dr. McGill’s ranch house was relocated near Buffalo Horn Creek. New cabins maintain the rustic feel of early ranch life.
