Greenwood can get VERY crowded in the summer time, but for good reason. The swimming is excellent, lots of space for everyone, and they have lifeguards on duty just in case. There are grills and picnic tables, but you have to get there pretty early to claim them. As for the campground itself, there are 50 or so camping spots that are pretty close together. But there are fire rings, which is nice for a county park, and one unique thing we saw was a horseshoe pit. No horseshoes this time, though, too hot and muggy. Typical New York weather. Overall, the park is more than I expected for a county park.
