No matter what direction you take from Newcastle, Wyoming you embark on a drive through time marked by spectacular views, gorgeous scenery and plentiful wildlife.

Our location is unique, representing the best of two worlds. The shortgrass prairie of the High Plains and the Black Hills meet - right here. Mount Rushmore, Devils Tower and other Black Hills attractions are an easy drive. From here you can lunch on the Canyon Springs Prairie near Custer's 1874 Black Hills route, drive the Cheyenne - Deadwood Stage Trail, or tour the shortgrass prairie's open and unending spaciousness - its sagebrush, ranches, tumbleweeds, antelope, prairie dogs, birds and more - echoing the past under unbelievably clear blue skies.

Newcastle Wyoming is on the intersection of US Highways 16 and 85. US Highway 16 is the most scenic route from The Black Hills to Yellowstone Park and the Tetons of Northwest Wyoming. US Highway 85, the CanAm Highway, links Canada with Texas, using the Old Deadwood - Cheyenne Stage Line in several locations.
