I always enjoy staying at the Historic Grand Union Hotel.
The Grand Union is a gem. An iconic piece of Montana history, the renovated Grand Union combines historic charm with modern amenities and exceptional dining. Its setting on the banks of the Mighty Mo is both spectacular and soothing.
The historic building on the Missouri River at the headwater of navigation, the friendly service and the walking path highlighting the history of the area made me excited to return next year!

The hotel is very lovely. The food was fantastic and the service was great. The bed was a little less than comfortable but everything else was amazing. Would recommend staying in this lovely hotel.
2nd trip to Grand Union. Despite bad weather had a great stay. Incredible step back into history in a 140 year old historic building. Great pillows and towels! Nicely renovated and maintained. Again, their restaurant may be the highlight of our stay!
Our room was absolutely beautiful. It was clean, quiet and had an amazing view of the river. Sarah, the lady who checked us in was very friendly and helpful. The bed was very comfortable and the jetted tub was a bonus. I will absolutely stay there again. A wonderful way to spend an anniversary.
This is a beautiful hotel. The saloon and restaurant are wonderful and our room was fantastic. The staff are friendly. We loved our visit to Fort Benton!
There is so much history here, a great walking trail along the Missouri River and the fall colors were really showing off. The restaurant was amazing. We had a suite that looked out on the river, absolutely gorgeous.
