Pros:
Ralph Williamson Memorial DGC (a.k.a. Lakewood Disc Golf) is a 20-hole course that sits in a multi-use park, in the Seattle sprawl south of downtown.
For a park in the middle of an urban neighborhood, this course has a lot of character and a unique feel! There are lots of holes with rolling elevation changes, and a few holes where the hills are pretty steep. Holes 11 and 13 are each 250'-300' throws that feel like about 100' further due to the steep upward incline. Hole 12 plays about 250' down the same hill, and it feels like you could throw a putter off the tee. In good weather, you can see the Olympic and Cascade mountain ranges in the distance from the top of a couple of these hills. There is also a pond lurking behind the basket on holes 5 and 7, and if you start your round on hole 1 you'll have to throw across it right off the bat. The hole is only about 200', but there isn't really anywhere to lay up if you can't throw that far (I don't consider some weeds with the parking lot right behind them a viable option).
Hole variety is solid here. There is a good mix of technical holes vs. more open ones. The vast majority of holes at least have a couple of trees to work around. Distances are mostly in the 200'-300' range, but there are a couple of longer holes. Although it isn't signed this way, the finishing hole #20 should definitely be a par 4 (it's about 600'-650' long) and holes #15 and #19 could be par 4s as well. Generally speaking, I would say there is enough here to challenge DG'ers up to an intermediate level.
The baskets are DGA models. They have definitely seen a lot of discs over the years, but are still in decent shape. Same story for the concrete tee pads. The tee signs looked like they had been recently refreshed. Each one has the hole number, map, distance, and par that I was looking for. Many of them show multiple pin positions, although there is only one basket installed per hole and it didn't seem like the current pin position was indicated on the sign in any way. There are several blind holes and I found myself walking up fairways on more than one occasion to identify the correct basket location.
There are at least two practice baskets near the parking lot. A couple of trash cans, benches, and porta potties are scattered around the course.
Cons:
This course has a lot of safety issues. The park appears to be very popular with both DG'ers and non-DG'ers. During my visit (late afternoon on a Monday), I believe I played past four different groups within the first ten holes (thanks to those groups for letting me play through!). The reason this is a problem is that several fairways are quite close together, and/or baskets are close to an adjacent fairway (e.g. #10/#11, #12/#13) - so I had discs thrown by golfers playing other holes land close to me on several occasions. There are also many throws (both blind and otherwise) towards non-DG amenities that could be in use. Walking trails are very much in play on several of the holes. The most egregious safety issue may be hole #19, which has a walking path running basically directly down the fairway, and a picnic shelter right next to it maybe 2/3 of the way down. Another unsafe one is #14 which plays downhill off the tee and has a walking path defining the left side of the fairway.
Navigation is also a big problem here. There is a kiosk next to the parking lot, but no map was posted on it during my visit. The map that was uploaded here was out of date. I dug around the internet and eventually found a map from a 2019 event which seemed to be pretty accurate (that is now the map uploaded here). I would never have found all of the holes without that map. There are arrows pointing to the next hole on most tee signs and hanging from the bottom of some baskets, but some of the walks between holes are long and it isn't always intuitive which way to go. I think the worst was #13 to #14 and #14 to #15, although #1 to #2 and #3 to #4 were also tricky. I'm pretty sure that some of the hanging arrows were also pointing in the wrong direction when I visited, which didn't help anything.
There is a long walk back to the parking lot after the finishing hole 20.
There are a couple of holes that just play straight across open grassy areas with no obstacles.
I don't think the course is long enough or challenging enough to keep better DG'ers interested.
