Shell Mound County Park is a small park run by the county with 30 sites. Many of the sites are unlevel and can be difficult to level a larger RV. We managed fine with our 30 foot 5th wheel. Some sites are small and suitable only for tents. There is a small playground and a washroom with showers. A boat launch at the campground is used by day use boaters many that are launching air boats. The air boats run late into the night so it can be very noisy. They were coming back in at 2 a.m. Next to the park you find another day use park with a boat launch, trails and fishing pier.
