The Mesa Preserve and the Mesa Recreation Park are totally different animals, but right next to each other. The rec park has a water park, tennis court, green park area and a marvelous hiking trail. There is a restroom.
This trail is rated difficult for about a short, but dusty rocky steep walk. Once to the top, you're rewarded with a huge plateau of level trails and view lookouts. Bring water. No trees or shelter on this level top walking area.
