Pros:
Lake Corriher has somewhat recently had six holes added, making it an 18 hole course. The course features DISCatcher baskets, concrete tees, and colorful tee signs (at least on the first 12 holes, I assume the final 6 will get signs soon though. The course creates one full loop around Landis Lake.
Lake Corriher is a heavily wooded course that features a premium on accuracy and shot shaping abilities over distance. As long as players can get off the tee clean and stay relatively close to the fairway, scoring even shouldn't be overly difficult here. Players will have to shape shots with a variety of angles if they want to park every hole though.
The limited elevation around the course has been utilized well. Holes 5 & 7 stand out as downhill shots that are very memorable. Some of the transitions were a bit long, noticeably between Holes 1 and 2, but significant effort has gone into making sure there is adequate signage to assist in navigability.
The course wraps around the smaller of two lakes and is quite scenic. The greens for Holes 1 (placed near a beautiful "waterfall") and 5 (built on a rock outcropping) were gorgeous.
There seems to be a lot of other activities going on at the park, including fishing, hiking, camping, boating, etc.
Cons:
While multiple angles were needed to throw well off the tee, there was not a lot of variance between the nature of each hole. They all felt very similar, narrow fairway with a slight shape, usually between 225 ft and 280 ft long.
The course has a few places were the rough was particularly noticeable. The dam on the side of Hole 7 was particularly rough, as were a few places around the new holes. However, none of the rough was oppressively bad.
Holes 5 & 10 through over/through camping areas. Which would be a shame to not throw if people are camping since these were two of the better holes in my opinion.
Hole 18's tee feels awkward. I can't tell if the tee was angled poorly, or if more trees need to be trimmed to make the gap more natural, but right now there are multiple trees creating a wall where the tee is pointed, but a sizable gap just offset from that area.
Would have loved for there to be two or three par 4s, just to help mix things up, since most of the course feels very similar.
Other Thoughts:
I first visited Lake Corriher when it was a 12 hole course, but had to leave before I finished my round due to time constraints. I decided to wait until the rumored additional 6 holes were added, and I am very happy I waited. All-in-all, Lake Corriher is a good, well-designed par 54 course that should be able to be enjoyed by all. So I am going to give it a 3.0 rating. To me, the course felt like the vanilla ice cream of wooded disc golf. It was a good course that likely won't blow anyone away, some people will like it more than others, but almost nobody is going to downright hate it. If you are ever in the area, it is well worth stopping by and playing a round and enjoying a peaceful walk through the woods.
