Our reason for choosing this park was that we had rented a Pop-up trailer to see how we'd like it, and this was the nearest campground. That said we found the pop-up to our liking, though it felt huge to us!
Campground was primitive, but that's what we go for anyway. Very little in the way of trails, thought the main one had Frisbee golf along the way, which was unexpected.
Hardy Dam Pond is actually a good-sized man-made lake, and as such, has no beaches to speak of. There's a small swimming area near the boat launch.
  We were there in July of 2020 and the "Trump navy" was out in force. Lots of motorboats overloaded with flags, some inconsiderate boaters almost swamped our little canoe. (This was shortly after a nationwide news story in which Trump boaters swamped and sank *each other* on a lake in Texas). 
Some of the campers partied late, and some boaters got an early start, so noise levels were unpredictable.
 Nearby, a great place to stock up on meats and Jerky in the area  is Galesburg Meats in Kalamazoo.  Also a must see is the Gilmore Auto Museum in Hickory Corners
