Pros:
Extremely nice tee pads and tee markers; tee signs; multiple tees; multiple pins; fairways and the area just off the fairways is generally very trimmed; a large variety of shots are required; the course is easy to follow (just be sure to go to the right, not left, after the 4th); the pins are all clearly marked with a number on top; the pins have orange highlighting to make location easy; benches; very significant difference between the choices of tee shots on some holes - different fairways in some cases!; practice basket available; wood chips on many fairways; discs are generally easy to find; the effort put into this course shines through
Cons:
No long holes - the two longest are 420 feet and 385 feet; most tees don't have branches until below 50 feet off the ground - this allows some really bad shots off the hook because the trees aren't usually too hard to get through; tee signs could use more detail; tall grass in some locations increases the chance of a tick grabbing you (one got my bag when I played); some areas (not many) close to the fairways will make finding your disc difficult; enough of a gap between some sets of trees to allow poor shots to end up in a favorable position; no elevation changes
Other Thoughts:
This course is very much on the high end of presentation - the first set of tees showed us that. Each tee has its own wooden post colored red, white, blue, or a combination of the colors that makes locating the appropriate one very easy. Each tee also has its own sign that shows a map of the hole (missing obstacles, unfortunately) and distances depending on pin location. The tees and signage are very impressive, especially considering the course is free!
There really are no glaring negatives about this one. The 'cons' listed above are, in general, pretty minor. It's really more of a list of elements that would need to be corrected to make this course 'perfect - 5.0'. Unfortunately, there are enough elements missing that a score of 4.5 is also too high.
This course is a must play. If I lived within 90 minutes, I'd be out here at least 5 times a season. The holes are very well designed, the shots required vary by quite a bit, and the variety of tees adds a lot of depth, but what will stick with me the most is the incredible presentation and effort seen in this course. There are so many little things that you'll notice as you play here that will make you appreciate Yulga.
Yulga was a high point of our disc golf trip in Central Wisconsin. It's not perfect, but nothing that is lacking is unforgivable. This course is nothing short of excellent - 4.0.
