This is a great campground. The best sites are lake sites (obviously), but there are some better than others. Look along the east side of the lake for a sandy beach off of your site. Those on the south side don't have a sandy shore, but still have a sandy bottom. 

Roughly 1.5mi trail around the lake and you can walk from the campground to Fallison Lake to do a hike there. 

Great to camp anytime of year. Though there aren't really electric sites, having showers and flush toilets is a huge plus.

We have Verizon service and it is spotty in areas, though given that you can see a cell tower towards Sayner it should be a lot better than it is. I think it is the heavy tree cover that impacts the reception. Even when we had 3 bars, it wasn't much better than the 1 bar at our site.
