We offer guided horseback rides into the Gallatin National Forest that surround West Yellowstone, MT. The Diamond P Ranch was founded in 1953 by Martin "Port" Portmann and his wife, Ocile Portmann. We offer three guided trail rides. Monday through Saturday ride times are 9:30am, 1:30pm and 5:30pm. Open mid-May through September 30 each year. Children are welcome. It's a great family activity. We are located 7 miles west of the west gate of Yellowstone National Park on Highway 20. Hope to see you there.
