Pros:
The equestrian course was the most secluded of the three courses at Turkey Lake Park. The course winds its way through the woods of the park and struck me as a "backyard" style course, with very short, technical holes.
There were a variety of fun shots demanded off the tee, but none of the roughs were too punishing, making this course a great place to bring a beginner.
Hole 17 is the most scenic of the holes of the course, with a cool view of the lake behind the pin.
The course benefits from proximity to two other highly rated courses. The daily car fee will get you into all three of the courses, and this course will be a nice change of pace from the other two.
Cons:
While the equestrian course made for an enjoyable round, there were several things that held its rating down.
Quality of disc golf - the disc golf here is catered mainly to beginners. There are no championship caliber holes, and no chances for bigger arms to throw anything more than a mid-range. Some of the holes were extremely short, even for a beginner (102' hole in the middle of the round).
Work in Progress - it's clear that the course is still new, and in time will likely improve in a few areas. A few of the "Par 4's" on this course are only par 4s because there is insufficient clearing of branches, debris, etc. Carpet pads are ok, but not ideal. I imagine this will change if/when this becomes a permanent course.
Other Thoughts:
If you are spending the day at Turkey Lake, you should definitely play this course, as well as the others on site. As a standalone course, the equestrian course is not worth going out of your way for, but it is a nice complement to the other courses at Turkey Lake.
