Raven @ South Mountain is great. Obviously, the most unique thing about this course is the distinct non-Arizona vegetation, which really takes you out of the surroundings. It's definitely one of the most beautiful courses in the Phoenix area.
It also has its fair share of interesting holes. Water is rare, but comes into play a couple of times on the front nine, as well as on the 18th hole. There are a few greens that are very well protected, so make sure your bunker game is in working order.
That said, it is quite pricey, with a summer morning round costing over $50. For $50, there are better courses to play in Phoenix. Also, it seems a lot of the people who play here think they are hot shots. Maybe it's because they can afford to spend $50 in the summer on a less-than-perfect course.
