This is a little tough to give a rating and I might have gone with a 3.5 if it was an option.
The park itself is okay. Nice trail to the tower, which was neat. The lake just so, so. We didn't fish, so we can't attest to that.
The campground isn't that big, which isn't an issue, but many spots are small and very sloped. The campground hosts were very helpful and friendly and went out of their way to assist if needed. Bathrooms were some of the cleanest I've seen this year!
The friends of pilot knob organization were also a positive! They had concessions each day and hosted a movie with popcorn on Saturday night, so that was very cool!
