This is a long, tough course but it is relatively flat so it's a friendly walk. it generally proceeds in a big oval shape that is about 3/4 of a mile wide, so there are times you're a long way from your car. There are 8 holes that aren't far from the parking lot though, and are a little more open than the rest of the course, so if you don't want to disappear into the woods at the back of the park, it's not hard to play 1-3 and then cut over to 13 and finish up a 9 hole loop. Holes 4-12 are in some pretty deep woods and are the toughest part of the course. You'll par 1-3 and feel pretty good about yourself....then suddenly you're stumbling to the back nine way over par and wondering how did that happen? 4-7 are all scorecard crushers even though they don't look that unfriendly.
The back nine is definitely easier than the front nine, so if you can get to 10 tee without being millions over par, the difficulty eases a bit, although it's not easy.
As the other reviewer mentions, Coleman Park is weird in that it forces you to re-evaluate what ratings you gave to other courses. In general, courses are getting better. The closest nearby course is the extremely popular South Hills which has at times been very close to Top 100 in the world. It always seems to hover just under the threshold. South Hills is a wonderful course, challenging to advanced players yet so beginner friendly that literally anyone can play their first round there and have a blast because there's hardly any rough (that's where I started) South Hills is where you should take every beginner, because if they don't like disc golf there, they just don't like Disc Golf. For a long time I've had South Hills at 4 1/2 stars. But after playing Coleman's numerous times, I had to reluctantly lower South Hills to 4 stars, because Coleman's is a step up from South Hills, yet it's not quite a 5 star course either.
The nearest two obvious 5-star courses to Coleman's are Faylor Lake (about 80 minutes to the north) and Muddy Run (about 75 minutes to the south). I have played both multiple times now, and both are Best of the Best type courses and deservedly ranked in the Top 100 in the world. So that's what Coleman's is going to be compared to when it comes to really high ratings.
Both have an advantage that Coleman's does not.... huge elevation changes, and extreme variety in the width of the playing corridors. At both courses, there are some holes that are very tight, and others that you couldn't hit a tree if you tried. Faylor also has vast amounts of water which make the course shockingly beautiful at times, and dangerous. That is probably why it ranks higher than Muddy in the top 100. Muddy has no water hazards at all, just lots and lots of rocky hillsides to throw up and down. I prefer Muddy, mainly because there you play up and down the hills. at Faylor, most of the steep hills are walks in between holes, which is less fun sometimes. Also, the back tees at Muddy are not incredibly difficult. Long, sure, but the pars are so friendly that on a good day you can reasonably think about shooting par. Faylor's long tees are so brutal that anything under +20 is a real athletic achievement. Coleman's back tees are in between that, unreasonable to think you're going to shoot par unless you're a borderline touring pro, but also not so hideous that you're going to double bogey every hole.
Coleman is kind of like Iron Hill in Delaware, a woods course with moderate up and down slopes and a few open areas but not many. There are no spectacular vistas, no top of the world shots into infinite space, and less variety off the tee. The playing corridors are all pretty much the same size other than the 4 holes that are in the more park-like setting (1,13,14,18). However it is a much friendlier course to walk than either Muddy or Faylor, and it is more difficult than Muddy.
Plus, Coleman's does have a lot of interesting things to look at, especially #15, a bizarre and unique hole with both baskets placed right on top of some old ruins. You'll just have to see it to believe it.
Coleman has an advantage over the other two in that there really aren't any prolonged weak sections, and there are no protracted uphill slogs. You feel pretty good when you finish #18 at Coleman, like hey, there's #1 tee right there, I just had a lot of fun making 11 bogeys and 2 birdies, so why not go around again! Muddy has a slightly bland stretch from 6-9, while Faylor has a bit of a lull from 10-14. But that's the problem with having spectactular land to work with, not all 18 holes can use the spectactular land.
I'd recommend playing one of the Yellow/Red hybrids at Colemans's for your first round and then if you aren't tired yet, do the other hybrid course the second time around. Both give you a nice full tour of the course without totally beating you up for 18 straight holes. Playing the all Red course is a real mental and physical challenge. Hole after hole of hit the gap and maybe you'll make a par, don't hit the gap and accept bogey (at best). Plus, the Red Course is now filled with OB ropes very close to the baskets, something you don't see much of at all on the Yellow course. The OB is intended to keep people off the mountain biking trail which parallels a lot of the holes. Playing just the Yellow course is a solid effort with tons of fun shots, but you do miss out on some cool Red holes.
I don't know if Coleman's will make into the top 100 in the world, but it's not totally crazy to debate it. I think it could someday sneak into the bottom of the list. Right now it has a 4.5 on Udisc and South Hills is at 4.6, but most of the Coleman ratings were done before there were tee markers and signs, so Coleman's has an unreasonably low 3.1 for "Signage" while South Hills has a 4.6. Coleman's score is higher in almost every other category though, which it should be. Once the "signage" score improves, Coleman's is going to be similarly rated to the other courses ranked around #100.
It's the best course in Lebanon County which is full of fabulous courses. Not only do you have South Hills, but nearby Lenni Lenape is much improved in the past two years and is also a wooded challenge. Twin Grove is nice, the two courses in Myerstown are short but well taken care of, and even the 9-hole Mt. Lebanon Camp Meeting gives you some really fun shots through the trees. Lebanon is becoming a very solid destination for a disc golf vacation.
The conditions are great at Colemans. There are hardly any thorny bushes, so you're not going to get slashed repeatedly which is good because it's not hard to get in the rough. But because it's sort of flat with short walks between holes, you're not exhausted before you're half-way done.
As for PDGA difficulty ratings, the first tournament was at Coleman there in late October 2023 A 57 on the Yellow Course was a 938 rating. A 58 was 929 rated.
The pros and MA1 played the Red Odd/Yellow Even hybrid course, including playing 18 as a par 4. This was a par 65 and even par was 955 rated.
The Yellow Odd/Red even course is a little more difficult, and I think even par on that layout will be 10 points higher.
Playing All Reds is a chore, but while it breaks your back early, the back 9 is filled with shorter par 4s that you can get to in 2 with a decent drive. There are a lot of par 4s under 500 feet. But because the second shots are so technical, it's hard to get close enough to the basket to have a realistic birdie chance. I think even par will be around a 980 rating.
The nice thing about the red tees is that even players of average distance can get a look at birdie at times. It's not all impossibly long beasts. If you have 250-foot distance you won't get a realistic birdie look on 1, 2, 4, 5, 6, 13 and 14, but the other 11 holes are all par 4s that are less than 600 feet and many are downhill. Two perfect 250 foot shots gets you to the basket. Good luck!
This week I played both the Red baskets at South Hills and the Red Baskets at Coleman. I shot +1 at South Hills (62), and +8 at Colemans (77). UDisc rated my round at 201 at South Hills, and 198 at Coleman's. So there you go, the Red Baskets are about 7 shots harder compared to par at Coleman's than at South Hills.
