Pros:
After Osage Grove, this is the nicest course in Clermont County, Ohio (East of Cincinnati).
W'burg's first 8 holes have concrete tee pads, as do the last 4 [edit: the other seven are now flypads!]. The tee markers are some of the best I've ever seen: a graphic representation of the hole stamped in durable (PVC?), with distances -and elevations!- clearly marked.
Williamsburg starts with open field shots which at least use the hill elevation, then runs alongside the woods & a small river/stream, ducking a few holes in that have to finish to the right. Then it has a long (535') 'lane' hole, and a pretty neat 8th hole that forces you to risk the ravine in front of the basket 281' away through the sparse trees, and the chance of going in the drink to the right.
The fun starts on hole 9 (Lower) and 9 (Higher) -I'll talk about that later--, where you go steeply uphill and 'into the woods', with an excellent variety of challenges up there, from a 90 degree left turn with a mando, to a short uphill ace run (if you can sneak past the obstructing trees), to a meadow 300 footer with a guarded basket at the end, and then to a tree nicknamed Karl who tries to swat down your effort to reach the basket, and the steepest drop shot in town, before you finally exit the woods on the 18th hole you play (...wait for details). You finish alongside and then across the outfield of the baseball diamond, where the big arms can stretch out and show 'em off a little.
So, a good mix of hole types, shots and distances, with a couple of chances at aces for everyone, and a couple that challenge even the Open players to deuce.
The park is usually uncrowded, has a nice kiddie playground, a picnic shelter, sand volleyball, restrooms, drinking fountain and pop machine, plus excellent hiking opportunities in through the woods, and near the river. Almost every tee has a bench, and trash cans are available. There is really little trash around, and the dedicated 'locals' do a great job of keeping the fairways clear, and the underbrush in check.
[edit 2014: "The Drop" steep downhill now HAS some stairs put in for safety. A few more were added after hole 9 to get up top. With flypads up in the woods, this course offers a tremendous amount of variety, challenge and fun for the Recreational to Intermediate skill level.]
Cons:
Some of the baskets are a little unforgiving/worn down: I've heard the phrase "You got 'burged" when my disc fell out.
Hole 8 is a disc devourer, depending on the level of the water to your right and the muddy ravine just before the basket.
Finally, the hole numbering is confusing (see below).
Other Thoughts:
I've taken to naming the holes, and used to record them as 1-9L,9H,12-20 (which totals 19). Now that they are numbered on here 1-19, I just ignore it when the signs differ. I once nicknamed the holes to limit the confusion. The names are descriptive for rhbh throwers: 1 mando anny, 2 flag raising, 3 open slopin', 4 pathside, 5 lo branch, 6 woods entry, 7 the lane, 8 riverside, 9 (9L) pathside, 10 (9H) cross-hill bridge, 11 the hyzer, 12 shorty, 13 the meadow, 14 tree guards, 15 the drop, 16 creekside, 17 the return, 18 anny fields, & 19 big arm finish. Play here once, and see if you like these names.
There has been (idle) talk of adding holes to get to 21-24 or even 27. There are some ideas which could put a hole after #9L which would solve the numbering confusion for now.
Overall, this is a real great course when it's dry, and a 'diamond in the rough': well worth the trip from other parts of town!
