Stayed over Columbus day weekend. Saturday/Sunday all electric sites were booked, mostly w/ families (lots of kids and dogs). Sites were level and spacious though some had a lot of standing water after almost an inch of rain. The staff was super friendly and helpful.
Spacious sites, cleanest bathrooms we've seen in the NY campgrounds. Overall a very nice experience. The beach is within the park, but best to get in the car to visit the beach
