I played the 3 courses at the Grand Traverse Resort this past October. Of the 3, I would recommend The Bear (Jack Nicklaus Design). It was challenging, made good use of risk reward and optical illusion. There a few holes which use slight elevation change and high grass marsh area to trick your eye from the tee box. The forced carry over the marsh looks much longer than it is.
Spruce Run (William Newcomb Design) is pretty straight forward, nothing special. It was a good course to play with my wife who just recently picked up golf.
The Wolverine (Gary Player Design) is right between the two. More challenging than Spruce Run, but I wasn't overly impressed. All 3 courses were very well maintained.
I stayed at the resort and played these 3 out of convienience and lack of knowledge about how many courses were in the Traverse City area. I talked with a few locals and they recommended many courses around the area. Most within 30 min drive of downtown Traverse City. I really liked the area and will definitely make a trip back to play other area courses.
