About Grand Union Hotel
Set on the banks of the Missouri River in the charming town of Fort Benton, MT, the Grand Union Hotel is Montana’s oldest operating hotel and one of the state’s most beautifully preserved historic landmarks. Built in 1882—seven years before Montana achieved statehood—it was once heralded as “the finest hotel between St. Louis and Seattle.”
Now listed on the National Register of Historic Places, the Grand Union Hotel has been meticulously restored to its original splendor. It blends 19th century elegance with modern comfort, creating a truly unforgettable lodging experience. Each guest room features antique-style furnishings, luxurious linens, and picturesque views of the river or historic downtown Fort Benton.
A highlight of any stay at the Grand Union Hotel is dining at the on-site Union Grille, known for its locally sourced, farm-to-table menu. Whether you're sipping a craft cocktail at the bar or enjoying seasonal dishes in the dining room, the Union Grille offers one of the finest dining experiences in Central Montana.
Just steps from the hotel, you’ll find many attractions that tell the story of the American West. Visit the Museum of the Upper Missouri, learn about 20th century plains life at the Museum of the Northern Great Plains, discover the frontier past at Old Fort Benton, and gain insight into Montana’s rugged landscape at the Missouri Breaks Interpretive Center.
Whether you’re a history buff, architecture lover, or recreation enthusiast, the iconic Grand Union Hotel promises an experience that’s timeless, memorable, and uniquely Montana. The Grand Union Hotel is more than just a place to stay, it’s an unforgettable destination that brings history to life.
Travel Tip: Fort Benton is a small community—if you are arriving after 9 pm, make sure to let the hotel know in advance to make arrangements for a late check-in.
