Pros:
- some of the best elevation change in the Chicago area
- good mix of uphill and downhill shots, with some level, but most having a hill in play somehow
- respectable natural beauty, though falls short of top tier courses
- concrete tees
- many technically challenging holes, but playable fairways and some more opens hots
- excellent high visibility orange DGA baskets
- most holes have good next tee signage
- navigation is pretty straightforward
- well maintained park with mowed fairways and reasonable rough
- every hole has 2 pin placements (only 1 basket in at a time)
- excellent full color tee signs with accurate maps
- good mix of hole lengths
- 10 and 13 are particularly unique and take advantage of uphill/downhill shots
Cons:
- a few safety issues such as cutting across hole 8 fairway to get to hole 9
- shares space with walking paths, which could potentially be dangerous
- no practice basket
- no garbage cans throughout course, only one bench i noticed on 13
- longest holes are interesting and not just long for the sake of being long
Other Thoughts:
Rolling Knolls is aptly named, with some of the best rolling hills I've seen in the Chicago area. This is a very good course, but for me it wasn't quite great - right around the 3.75 level, and in my opinion just slightly overrated. It's missing some of the nicer amenities (bathrooms, water fountain, garbage and benches, practice basket) of top tier courses, but I can overlook most of that. I think a little more variety and taking advantage of water hazards a bit more might bump this up for me.
There is one ditch i saw that is a pseudo water hazard but doesn't come into play much. There is also a large lake/creek that isn't much of a factor, but I suspect it might be over the property line, unfortunately. You can see this from hole 13, which was probably my favorite hole - a great downhill shot to the basket a bit short of the lake. It's only 215', but I enjoy some of these downhill shots. Hole 18 also throws over water but at 196' it isn't an especially high risk.
I also thought hole 10 was really cool, but saying I enjoyed it might be a stretch. It's probably one of the steepest uphill holes I've ever played, and I think it was my only 5 on the day. It definitely forces you to make solid uphill shots at an angle I've rarely had to pull out.
The few safety issues here didn't come into play much, but they should be noted. At least one hole cuts back across its own fairway to get to the next basket (8 to 9) and in general, there are walking trails all over the course. I didn't see a single person on these, but if someone was unfortunate enough to get near an errant throw, it could be bad. Otherwise, the park is devoted to disc golf, which is great.
Natural beauty here is average for the Chicago area, and there is a mix of open and wooded shots, with some very long ones that play more like the old golf course this used to be. The elevation change makes up for the lack of natural variety in Chicago. I think the course designer used the space available very well to make an intriguing course.
One nit that isn't really the fault of the course - when I was trying to play hole 18, a few guys were using the basket as a practice basket, since it's near hole 1's tee. This is bound to happen with no practice basket, but these guys putted forever with me standing there waiting to tee off and couldn't be bothered to let me finish my round. Again, not really an issue with the course, but a reminder to follow basic course etiquette.
There are plenty of complaints in the reviews about this course being a "disc eater" and having thick rough. Admittedly I played this course in April so things weren't especially overgrown, but I didn't have this issue at all. I suspect some of the people who had issues here haven't played some of the most challenging wooded courses out there. I played solo and felt the rough was pretty reasonable here.
The tees, tee signs, and baskets here were all great. I think from 3 to 4 is the only place I had some navigation challenge, and I think the next tee sign may have disappeared. Some of them are temporary signs in the ground and some are permanent, so making the rest permanent would be an improvement. I enjoyed playing this course, but it didn't quite have the X factor for me vs. some I've played recently. It's definitely worth a bit of a drive if you're in the area. It beats most area courses and there are several others very close by if you want to make a day of it.
