Access to site
Fort Union Trading Post sits on the Montana/North Dakota border, 25 miles southwest of Williston ND and 25 miles north of Sidney MT. The fort sits on the North Dakota side where the main parking lot is 1/4 mile on the Montana side. There is a slight climb in elevation when coming from the smaller parking lot which is about 500 feet from the fort.

Park grounds are mostly accessible to wheel chairs, but there are some stairs. A ramp to the Bourgeois House Visitor Center will be installed on request and parking lot shuttle service is available for visitors who have difficulty walking. Please have a member of your party contact the ranger at the Visitor Center desk. Video program includes closed captions and narration. A hands-on exhibit of animal pelts is available.

Plan ahead! Due to the ever expanding oil activity and housing shortage in our region hotels and RV camping spots should be reserved ahead of time.
