Pros:
What a crazy course. Sunny Lake offered me a round unlike anything else that I have experienced, for better and for worse. This is a super tough course in the woods of Eastern OH, incorporating water shots in many different ways throughout the round. There is both an amateur and a pro course that separate early on in the round and share tees at times. This review is based upon the gold course layout.
For the gold layout, the designers were definitely going for a championship-level course. It measures out close to 11,000' and has eight par 4's and four par 5's. I have never seen so many 6's in my score before, so the course succeeded in kicking my butt. The course starts out well with a fun shot that starts out in the open and then hits a tight gap/sharp angle in the woods. Holes 2 and 3 also offer fair but challenging long lines in the woods that play to tight gaps where the basket is located.
Use of water and elevation changes is done well here, with many streams and ponds coming into play. Baskets are thoughtfully placed, often being tucked away among trees or on a slope.
The tees are awesome and the tee signs are very descriptive. The next tee signs are very helpful and without them it would be nearly impossible to get around. This is a beautiful park, and it was very well maintained for the most part.
Cons:
The main thing I take away from playing here is that it is hard for the sake of being hard. I'm all for playing a championship-level course. Just came back from a trip where I played Nockamixon and loved every minute of it. But I felt that this course is unnecessarily hard, if that makes sense. Hole 5, for example, is a tough water carry and has potential to be a great hole, but there isn't really a clear landing zone at the other end. It's basically, you throw over the water and hope that somehow your disc finds its way through a gap somewhere to get to the pin.
Another example is 8, which is 1,000+ feet. The fairway is a very tight gap that you can't really even use a driver on. I found myself often using mid-range discs on these longer holes because of their super tight layout. Now, some of the holes are done really well, like the first couple and the 2-3, but I felt the majority of the round was over the top. The holes didn't always offer true fairways and clear landing zones. The course would improve greatly if more clearing was done and more trees were taken out.
The layout of the course is definitely confusing. You're often playing shared tees between the two sub-courses, but they are differently numbered holes and play to different baskets. I found my way around ok, but you really have to pay close attention to which layout you're following and which basket you're meant to throw to. I really think they should switch the basket colors, since the shorter layout has orange-coated baskets and the longer layout uses the traditional color. You can already see most of the shorter baskets from their tees anyways, so why not switch to make them easier to scout on the gold layout. This is the most confusing course layout I've had to follow. A guide is highly recommended.
While there are a ton of 'next tee' signs, I still feel more could've been used.
For hole 5, you have to walk through the fairway to get to the tee. 16 is virtually unplayable and seems to often get neglected with knee-high grass.
It's a very long hike and doesn't loop back to the parking lot mid-round. I don't normally mind this, but it would've been nice for a course this grueling.
Other Thoughts:
Since this is a huge park, there are numerous entrances. Make sure that you take Page Road to get there. The designer for this course has done an amazing job in this area, and I appreciate the desire to build a championship-level course. It's still in its early stages, but I think the course would really improve with a lot more clearing. Sunny Lake has a ton of potential and is in a beautiful setting. Like I said, it does have some great holes. However, the layout of some holes and the course in general can be improved to be more player friendly. I would love to return if more clearing is done at some point. Again, highly encouraged to play with a guide.
