McDonald Mountain Ranch is located on historic property in the heart of the Black Hills near Keystone. We are situated in the trees on 20 acres of serenity. Mount Rushmore is right “up the road” via Iron Mountain Road and Custer State Park is just “down the road,” about two miles away. Each of the two rental units has cooking facilities, private baths and private decks. Both are supplied with breakfast fixings that include fresh fruit, juice, coffee, pastries and a variety of cereals. Our season dates are May 1 through September 30.
