It's always good when the little regional parks are able to stay open to serve the locals. Camden is a no-frills parks without big thrills but quite a few old-school flats. A couple that are well run include their Whip and gravity-powered Haunted House.
Camden Park is certainly worth a visit for the hard-core wooden-coaster enthusiast or if you are passing through the area, but just don't expect to be wowed by the park.
