Parking: free if you park off campus and walk half a mile. Otherwise you need to pay the school. Parkings worse obviously if you go on a busy school day.
Entry: free with advanced booking, give your name at the front.
This is the best kept, best quality garden I have seen by a college/university in Southern California. It's somewhat small but they pack it full of quality plants and Japanese garden decorations. They have of koi fish in their pond. Very clean, green, and scenic. Imo its better than UCLA and Cal state Fullerton's gardens.
