well whenever we drive from Phoenix going west on the 91... off the 91 freeway before you hit the 57 theres a place with a waterslide, a castle, and mini golf tucked in an industrial area... Although not having been in Cali in over 6 years, I can only back up that one since we see it on the freeway. Oh and in Riverside which is a bit of a drive there is Castle Park which also has a few rides along with a fun log ride and S&S tower ride there... so theres mini golf and a log ride... lol!
Does anyone know if Golf N stuff in Norwalk is still alive, or that family fun center in fountain valley? I cant back those up but as a kid I remember them being not too far from the DLR area... though Norwalk is not the greatest of areas if i remember correctly.
Camelot minigolf is an EXCELLENT course. It has 5 courses ranging from easy to hard. It's meticulously maintained and is loads f fun. They also offer laser tag and tons of arcade games in addition to the waterslides which are open easonally from Memorial Day to Labor Day. It was rated one of the top ten minigolf courses in the country and the best family minigolf course in the country by Travel Channel.
