As mentioned above the area around Roraing River, Golden,Eagle Rock and Table Rock Lake in Missouri is a beautiful place. In addition to mentions above it is reasonably close to Branson.
I have relatives who live at Eagle Rock and we visit there at least once each year. It is easy to drive from Eagle Rock or Golden to Branson , take in a show, etc, and return the same evening. I cannot recommend an RV Park there since we park our RV on a cousin's farm when we visit but we enjoy Roaring River, the fish hatchery there, the Marina on Table Rock Lake at Eagle Rock, and the whole area there.
If you are able try to get there in the Spring when the Red Buds and Dogwoods are in bloom. You will enjoy it.
