The campground is easy to find if you take highway 81 south from Yankton and then turn right onto 121 west. The signage is easy to miss, but right where 121 makes a bend to the left, the road down to the Tailwaters campground departs on your right and descends down to the river. All the sites are in a line facing the river. Some sites are for tents and the rest have electrical hookups. There is a pit toilet at the far end and a shower house with flush toilets in the middle of the campground. There is also a boat ramp near the entrance. My only complaint is the"yard lights" that are on all night. They are incredibly bright. It would have been nice to have it dark and see the sky.
