Love this course! Rather difficult relative to par but no truly crazy holes. Good variety. Well planned course with plenty of unique, enjoyable holes. Don't skip out on the extra nine because the par 4s are the best holes on the course.

I really don't like the design of hole 16, and hole 27 just being an easy ace run to finish out is kind of an eyeroll for me.

This is a marathon of a course. You can make a day out of one round if you're in a group. Plays through a mostly wooded area behind some softball fields. Lots of planes flying overhead.

-Tees are high quality concrete and are sized appropriately
-Tee signs are very nice and also helpful
-Baskets are nice quality, Mach X for the most part, a few Mach V (I think) sprinkled throughout the course.
-The Fairways are amazing, I love the woods with a grass fairway, it looks really good, and is easy to locate your disc in.
-This is a very flat course, but the occasional mound or hill is always used as a part of the course, Hole 20 in particular.
-This is a very wooded course, so the trees come into play a lot, and when they do it is great. That being said, there are some 500ish' holes out there, and those have trees on the sides or maybe one or two in the middle to let you rip one out there.
-Paths are worn down to perfection, you can pretty much just follow the paths to the next tee.
-While there is the occasional graffiti artwork on benches, this course has a good vibe, which is mostly derived from the beauty of the course.
-Almost (if not all) holes have benches at the tee.
-Wide variety of shots here, and millions of unique situations to get into, I had to throw a roller (I never throw rollers).
-This course gets a 4/4 on the new Shoe Index, unless you come here on a rainy day and jump around in the mud, your shoes will be clean.

-Baskets are sometimes really difficult to see, and at times not completely clear.
-The roughs are brutal, if you are on the edge, it's all good, but if you go deeper than 3 feet, kiss that disc goodbye.
-As this is a long course, in a big park, there are a few hang-ups with Navigation, if you want to split the course up, it is hard to do so without a really long walk back to the parking lot.
-This course isn't beginner friendly, many holes are too long for beginners, but, they could be a good thing for some people, I can't really decide if it's a pro or con, I can throw like 330' so I'm OK with long holes

If you are made uncomfortable by loud noises from planes or loud noises in general, you should probably not go to this course, it is probably 10miles north of the International airport.

More Birdie/Ace runs than previous 18 hole layout
Nice big pads
Multiple pin positions on many of the 'new' holes

Not all baskets are the same - watch out for the 'Cool Shoez' baskets without nubs!

If you're visiting Seattle and can only play one course in town, this is the one to play. Even with all the 'cons', I'm going to rate this course very high for the excellent layout and challenge it presents. This is not a course for beginners to experience their first round - Lakewood is a much better course for that. This is a course that will test your mettle and punish you if you get off the fairway on most all the holes. This course was recently expanded from 18 to 27 holes (THANK YOU KEITH AND CHAINBANGERZ!!!) The 'new' holes are 1-5 and 24-27, with the original 18 filling in the middle 6-23. The 9 new holes add a lot to the course, making it much easier in my opinion to score a par or better on the course. Previously there were really only 3 or maybe 4 ace-able holes for the mortal disc golfer, the new holes effectively double that. Finishing a round close to par is now within the grasp of the 920 rated player. Big arms are definitely rewarded here, but if you're looking for wide open field shots, you've come to the wrong place. The course plays a lot easier in the winter with the leaves down and the grass and blackberry in retreat. In the spring and summer be sure to watch your disc very closely, as it's easy to lose a disc in the schule on several of the holes. The parking lot is nice, however car prowls are common so hide anything of value and lock it up.
For first timers - be sure to look for the next tee signs under the baskets for navigation. Most confusing is likely #3 to #4 which necessitates crossing the path by the 27 tee - and the walk to #6 (old #1) - follow the path from the #5 basket through the foilage to the paved trail and follow it to the parking lot. Signs, benches and trashcans/service (and mowing in the summer) are all that's keeping this course from being a 5 - and I hear benches are on the way - so we're getting there! It's a jewel and I'm so thankful to the volunteers and dedicated crew that built and maintain it -Thank you.

9 new holes, making it a 27 hole course
New signs at each hole put in for tourney AND new metal arrows pointing to next tee
New holes have AWESOME new baskets/chains, almost no chance of a "fly-thru" on these chains
New holes done extremely well, using lines of trees and clearings perfectly
Its like a whole new course! AWESOME JOB, KEITH!!!!(and those who helped him)

No bathrooms except near the "new" parking area

Long course and very challenging. Not a con for some, but beginners might get frustrated here. Nearby Lakewood course much better for beginners
