Where are the campers park

All over. Camper sites throughout. Water, or woods. They have a map in their website

As you drive into the park the campers are parked to the left, before you get to the gate house, going around the ball field. The seasonal campers are all parked to the right of the gate house. You'd have to check with the camp ground on their availabilities. They do have wash houses centrally located on those sites as well.
