Fort Union Trading Post National Historic Site
Fort Union Trading Post was the most prosperous fur trading post on the Upper Missouri River, annually exchanging over 25,000 buffalo robes worth more than $100,000 in 1800s currency. Families explore the reconstructed Bourgeois House, Trade House, and palisade walls while walking the same ground where Assiniboine, Crow, Cree, and other Northern Plains tribes conducted peaceful commerce for nearly four decades. The park's unique location straddling the Montana-North Dakota border offers sweeping views of the Missouri River valley. Unlike military forts, this trading post represented cooperation and cultural exchange, making it a fascinating place for kids to learn about early American commerce and Native American history.

Program Details
Best Ages for Fort Union Trading Post National Historic Site
Ages 3–7
The Junior Trader component truly shines for younger kids who love the hands-on experience of earning their fun-fur buffalo robe. While the Junior Ranger booklet targets older children, little ones enjoy exploring the reconstructed buildings and hearing stories about frontier life. Rangers are wonderful about adapting activities and helping families with mixed ages participate together.
Grades 4–6
This is the sweet spot for the Junior Ranger program, with activities perfectly designed for elementary school kids learning about trade, cultural exchange, and frontier life. Kids this age love the detective work of finding answers on interpretive signs and museum exhibits throughout the fort. The combination of history, hands-on activities, and the trading simulation keeps them engaged for the full hour.
Ages 13+
Teens and adults absolutely find value in the program, especially those interested in early American commerce and Native American history. The park's focus on peaceful cultural exchange and economic relationships offers a more nuanced historical perspective than typical frontier stories. Older participants often spend extra time in the museum exhibits and engage rangers in deeper conversations about the complex relationships between traders and tribal nations.
Planning Your Visit
Getting There
The visitor center parking area easily accommodates large RVs and vans with plenty of maneuvering space. Located directly on Highway 1804 at the Montana-North Dakota border, it's easily accessible from both Williston, ND (25 miles northeast) and Sidney, MT (25 miles southwest). No reservations needed for the Junior Ranger program — just walk in during operating hours.
Van & RV Notes
The parking area works perfectly for high-roof Sprinter vans with level ground and ample space for turning around. While overnight parking policies should be confirmed with rangers, the location is ideal for van life families exploring the region. The nearest full-hookup campgrounds are in Williston or Sidney, about 25 miles in either direction.
Best Time to Visit
Late spring through early fall offers the best weather for outdoor exploration, with summer months providing more living history demonstrations and ranger-led activities. We truly love visiting in late September when crowds thin out but weather remains pleasant for walking the grounds. Winter visits are possible but focus primarily on the indoor visitor center and museum exhibits.
How Long to Spend
Plan 2-3 hours total to complete the Junior Ranger program and thoroughly explore the reconstructed buildings and grounds. The one-hour booklet completion pairs perfectly with time to watch the orientation film, visit the Trade House (summer only), and enjoy the museum exhibits.
Don't Miss
The Junior Trader experience is absolutely worth it — watching kids' faces light up when they trade their earned buffalo robe with a ranger creates lasting memories. The Bourgeois House museum exhibits bring the diverse cultures and daily life of the trading post to vivid reality with artifacts and interactive displays that complement the Junior Ranger activities perfectly.
