The Muley Park Landowners Association is an association of 21 lots of 35 acres or more, in the foothills of the Rocky Mountains just west of Fort Collins and Loveland, Colorado. The lots divide 1,000 acres that was purchased from the original Milner Ranch of Ben Milner, who was descended from one of the original pioneer families of the Masonville area. The lots are on the east and west sides of Milner Mountain and range in elevation from about 5,300 to 6,000 feet. The roads are all private, and only owners and their invited guests may use the roads.
