While I may be a fan my knees from hiking one of the trails are not ;) I don't recall how much it cost to get in as the driver paid but there were 5 of us in there and away we went. It is a beautiful area with all of the cacti and mountains and hills. There are many hiking trails but we split up with two of us going around one of the hills and the other three (including me) going up and over the hill. The view from the top is pretty darn good!
There are places to have a picnic and grill as well as play areas for the kids and one area that had fitness machines to try out. There are areas to camp as well as a shooting range and archery field. It made for a fun morning and I'd happily go back.
