This campground area is beautiful! We stayed here 3 nights. We arrived on a Thursday and there were plenty of open spots. Friday they open some of the other loops up for more people to stay and it did fill up for the weekend.
You can get some cell service but only in choice areas (at the front by the water spigot and some of the roads leading down to the lake. We were not able to get any cell service (Verizon, AT&T, or T Mobile) in the electric loop.
This area is a primitive area and is not really set up for RVs. Don't get me wrong... RVs can definitely fit in most of the camping spots but only 1 loop has electricity, there is no sanitary dump station, and the water spigot does not have a way to hook up a hose to fill your tank. If you dump your tanks and fill with fresh water before coming you should be good.
It does have vault toilets... no showers. The toilets were very clean for vault toilets.
The lake area is beautiful with a swimming area, fishing pier, and pavilion to eat or sit under for shade. It looks like they really keep the area cleaned up!
Another little note that we learned is that the park rangers can help you move sites... or even campgrounds if your site is not working for you so you don't loose out on money like we did. This only applies to other Shawnee campgrounds of course but there are quite a few to choose from!
