Prewett Creek RV Park and Campground is off of I-15 just south of Cascade, Montana. It actually sits behind the Prewett Creek Inn and Missouri Inn Restaurant and Bar of which neither are part of the campground. Continue driving behind the inn through an opening in the fence and there is a small building on the right for self check-in. If you have any questions, need WiFi password, etc. you can call the owners. Their phone number is posted on the check-in building. They were extremely friendly and nice.
Campground: Prewett Creek Campground
Location: Cascade, Montana (south of town along I-15)
Services: FHU (50AMP)
Comments: A small campground with easy access from I-15 nestled in a gorge along the Missouri River. Even with the close proximity to I-15 there was no noise since the campground is behind the mountains. The sites are long and level, the WiFi is terrific, the scenery is beautiful, the fishing, we hear, is fabulous, and there is the occasional wildlife passing through the campground. We loved it here.
The campground only has about 14 sites situated in two rows. It was perfect for an overnighter.
Prewett Creek is next to the campground as is the Missouri River. If you love to fish this is the place!
