When you pull into Beaver Creek Family Campground you pretty much have two choices: either you go left into multiple Pine tree sites or right into two cabins and more RV friendly open sites. A few of the RV sites have electric, but no water for their tanks. I suggest the pine sites for any tent or hammock campers. I stayed in one of the first set of 3 pine sites numbered 43, 44, and 45. There is some brush and cover between these sites, but each has a pull in parking pad. If 45 was occupied with a RV, 44 would not be as nice as it was. Backing into 44 and 45 would be tricky as well. To be fair any larger RV that came in better know how to get through tight quarters.
The back area of each of those 3 sites looked best to get even ground for a tent. My buddy hung his hammock between the tree to the left of the picnic bench and to a tree back and left in the picture of site 44. Site was fairly clean, but be sure to move the pine tree duff away from the fire pits to be safe.
Probably the nicest pit toilets I have experienced and while we didn't use, it the sun shower building would give anyone privacy if they had packed a portable shower. Lots of trails to choose from and the pioneer village in the state park gives you many options to spend the day. Had some luck fishing at the Canoe/Kayak area in the South East area of the park close to the Group Camp Sites.
