There used to be some really cool old-fashioned features there, like rectangular mounds right in front of greens, etc. It's a fun place to play golf.
I remember playing there once when it started snowing as we made the turn, and then there was lightning - perhaps the only thundersnowstorm I've ever experienced. My good friend's father's hair was sticking straight out away from his head, there was so much electricity in the air.........
Since you're in the area for a few days, you might consider driving over Trail Ridge Road down to Grand Lake, and there's a few courses over in that area, like Grand Elk or the courses at Pole Creek. More than an hour from Estes Park, but not that far if you're already in Grand Lake..........I haven't played Grand Elk, but Pole Creek used to be pretty good, if memory serves....
Have a great vacation. It's beautiful up there !
