We spent a week at spring mill state park. The site we where at was heavily sloped, the only flat part was where they put the fire pit at. When we looked at the other site most of the shaded sites that had some privacy where also heavily sloped, the best site we found was #9. The village, twin cave tour, and trail 4 where fun. But we weren't fond of the other trails we where on, they didn't have many view but trees (which would of been better if it wasn't so hot at the time).
