Pros:
Forked Run is located along the OH-WV border and the course plays widely throughout this state park. It starts near a small pavilion on the left shortly after you enter the park, with signs pointing you to hole 1. It presents a desirable level of difficulty: a great blend of tight, technical shots in the woods and longer, open shots that make you have to fight for par. Distance with accuracy is tested here. However, it isn't challenging to the point where it's not fun. The two sets of tees truly give you a nice option for the level of difficulty you want to play.
There is good signage here, with tee signs and a lot of 'next tee' signs throughout the course. This helps out a lot since the course is so spread out and plays in different parts of the park. Since it is a long hike, benches are plentiful. The tees are awesome, concrete and very large.
There's a great mix of holes with a variety of wooded and open shots as well as moderately wooded holes that force placement shots. Hole 3 comes to mind as a perfect placement shot. It starts out open but a solid approach depends upon a well-executed drive in front of an opening into the woods. The design also makes nice use of the elevation provided with some steep uphill (7-10) and fun downhill (13, 14, 18) throws. 14 is a highlight, a downhill left to right shot in the woods with a challenging pin position on a steep hill. Being 24 holes long, I didn't feel that there was much redundancy. This is uncommon for a 24-hole course that isn't championship level. I think this is mostly due to there being a sequence of open then tight holes back to more open shots, etc.
Well thought out pin positions add to the challenge, with many being on a slope or among a patch of trees. Hole 17 is an open shot on top of the end of a reservoir. The pin is on a very steep hill that calls for a touchy approach.
The land is very well taken care of, with limited rough and chances to lose discs.
Cons:
While the navigation is aided for the most part, there are some tricky areas and the direction of the next tee isn't always obvious. I had trouble finding holes 7, 14, and 23. For each one, head to the woods on the left.
I'm not sure how regular this is, but a few holes were pretty swampy when I played. Hole 7 had a pond in its fairway that I just played around.
There is a great variation of holes, but some of them were pretty straight forward. There weren't really any true signature holes that were a blast to play. That more than anything keeps this course from being among the excellent (4.0 and higher) rated courses for me.
With the state park being in a secluded area, the course itself doesn't always feel secluded. There are times where you play around a parking lot and a fishing area. A few holes play near the park road.
A little nitpicky, but the tee signs had 3-6 pin positions marked out, often being very different. This caused me to have to search for the basket on the blind shots. The marked positions didn't always correspond with where the pin was located.
There is no real parking area by the start of the course, I just parked next to the pavilion which is out of the way from other park activities.
Other Thoughts:
Forked Run is a very solid course that offers a lot of variety and makes great use of the state park's land. It offers a nice balance of challenge, difficult to achieve par without being too demanding. There aren't any real big detractors to the course, so I think any player would enjoy playing here. Unfortunately, it is a little out of the way in terms of other courses and pretty much anything else. I definitely encourage a stop here if you are near the area.
