When you first drive into the state park, you are overwhelmed by all the trees and shade and think you are in a nature wonderland. We stayed at Pin Oak Lake because our RV would not fit at any of the other sites. The sites are wonderful. They are large, level and have a lot of privacy. The staff are wonderful and very helpful. The problem is that there are no trees to speak of for shade. A previous review states that straight line winds knocked all of the trees down. Not true. We spoke to people that were there when this part of the park was built and they said they just went through and knocked all of the trees down. Unfortunately we stayed there when it was 95 degrees and after three days had to leave because we were getting sick. We might stay there again if the temperatures were in the 70's. It is a shame that this campground doesn't live up to the majority of state parks in Tennessee.
