Fairfield Park's unique dual layout makes the most out of a great piece of land without overcrowding or watering down the quality of the disc golf by trying to cram in two completely distinct 18 hole courses. The White and Gold layouts would be great courses in and of themselves, but it is their combination in a single location that really elevates Fairfield Park.
The course has always been well maintained during my visits, and while they don't have the best amenities (only a single port-a-potty, no pro/snack shop) there are enough little extras that make this feel like a disc golf course, and not just some baskets in a park. After you pass the large, colorful course map there is a "warm up hole" near the parking lot. I wish more courses had this. It is really nice to get a handful of tosses in on a shorter, open hole to warm up your arm before the first hole, and being able to do that to an actual basket is great. Once you have thrown enough to this basket, you can take a couple of steps to two more practice baskets, and get some putting in before finally making your way to the first tee pad.
The course starts you off gently with 3 largely open holes where long grass shapes the fairways. I am generally not a fan of using tall grass as rough, but these holes are straightforward enough, and with wide enough fairways, that it isn't much of an issue (The tall grass here also isn't nearly as thick as many others I have encountered). While these holes don't require the level of shot shaping as the rest of the course, being open, they force you to deal with the wind frequently present, and have enough other small things going on to not be boring and still go well with the flow of the course.
Once you play 4's long turning shot (stay out of the rough on the right side!) and enter the woods on 5, the real test begins. The majority of the holes at Fairfield play through tight, but very fair, wooded allies. The elevation won't blow you away, but you will be throwing left, right, up and down to fast greens and over water for the next 10+ holes. There really is a delightful variety here not found at many other courses. The round finally comes to a close as you exit the woods with a massive 810'/905' downhill shot back towards the parking lot with plentiful OB.
Navigation is generally easy here, as there are plenty of signs directing you to the next hole. The tee signs only have the number and distance, which is usually sufficient, but a visual description of the hole would be nice, particularly since many of the longer gold holes are blind and require a good bit of walking to find the basket if you aren't familiar. Benches at the tee would really be nice as well with all the walking you will be doing, and would add to the "completed" feel of the course. There are a decent number of trash cans throughout, and the tee pads are large and grippy. The baskets aren't the best, but still catch well.
My last little nit-pick for this course might sound a bit odd. After each of my rounds, both on the white and gold layouts, though I enjoyed them immensely I found myself wishing there was a third layout in between the existing two. This might just be my own skill level falling between the cracks a bit, but since my rating tends to float right around 900, I figure there are enough people that may feel the same way as me that it is worth mentioning. The white layout has a lot of fun shots, but really lacks distance for the majority of the course. I went almost the entire course without pulling out anything faster than a buzzz, and drove with a putter on the majority of shots. Holes 3, 4, and 17 give this layout a huge chunk of its length.
When playing Gold, however, I occasionally felt overwhelmed by the massive, tightly wooded shots, and watched my score balloon to almost 150% of what I shot on the whites. Others in my group suffered even worse. The gold layout is well designed, but definitely aimed towards more advanced players, particularly holes 10-15. I don't expect each course to cater to my specific skill level, and I didn't really count this against the course in my rating, but a third layout that was more than pitch n' put distance for 2/3rds of its holes, but not quite averaging 450' per hole, would be great. I guess my point here is, if you are a mid-level player with a rating in the ballpark of 900, expect to either be beaten down by Gold, or not sufficiently challenged by large stretches of white.
Fairfield is a fantastic course (two courses? course and a half?) that has everything from water carries, long bomber shots, tight ace runs, and massive par 5s that require you to hit landing zones. There really is something for just about everyone here, and I don't think anyone would regret making the trip to play one or both of these layouts. As usual, bring bug spray, don't let the mosquitos get you down, and have a blast playing some terrific disc golf.
