There are several campgrounds to choose from. We chose the Deep Fork campground because it offered several spots along the Fourche Maline River. Great fall views and perfect autumn weather. There was only one other overnight guest, although there were a few fisherman during the day. 

We didn't use the restroom facilities, but they looked like they had seen better days. Fire rings and grills were okay. Concrete picnic tables.

Lots of hiking options throughout the state park. We saw some incredible views on the Robbers Cave trail. It was poorly marked, but even if you wander off the trail you will be okay. If you go too far you hit a dirt road the loops around the back of the trail and you'll know to circle back to the trail area. 

The main camping area near Whispering Pines had a park office and a small grocery store. Not a huge selection, but you will find the essentials.

Cell service was spotty throughout. One spot you wouldn't have service and 30 feet further you'd have decent LTE (Verizon).

I would definitely visit again. The lake appeared to have some summer activities available, including a pool. But the autumn views and weather will be my choice time to visit.
