Big M Marina and campground is absolutely awesome! Nestled snug on the Missouri Arkansas border is a gem of a campground. Large grassy sites some most with electricity and water, and some with sewer. Sites are paved and pretty level. Great play area for kids. Well kept bathrooms and showers. Marina has a great restaurant that you will not be leaving hungry. Nice marina store. Boat rentals as well as slips. The swim area was very clean and accessible even though it was flooded. Only inconvenience were the roads in. Be prewar warned. It is a nail biter. All in all definitely a 9 out of 10!
