Mouse River Park is a large RV park nestled between the trees and alongside the Mouse River(Souris River). There are many sites but most seam to be seasonal from local people who come here on weekends. So, there are limited sites for people looking to spend a few nights and move on. Darrell is the caretaker and a great guy. Call him before you come and he will reserve you an available site. $15.00 a night with water/30amp power but there is no sewer hook ups. They have community restrooms and showers. Mouse River is a beautiful place and is surrounded by a National Wildlife Refuge!
