There is still a nice beach at the state park, but it's about 1/2 mile up the road from the campground. Best part is that it's connected using the bike trail!
I'm planning on tent camping there this summer and was glad to come across this video, looks like a great place. Reminds me a little of Wilderness State Park in Michigan outside Mackinaw City where I camped a lot as a kid, highly recommend that one if you haven't been.
