Secluded rv sites in ny

Check out Letchworth State Park. Sites are huge and very wooded. We were recently there for the first time and our site was probably 100ft deep and about as wide. Heavily wooded. I'ts electric only, but did have 50 amp. Nice waterfalls and hiking . In an earlier post, someone mentioned Hickories Park... it's really just a large open field. We stay there for a few nights while traveling across the state. It's not what I call secluded. but one of the few RV CG's that can accomodate large units in that area.
