Pros:
Langley Passive Park was very impressive from beginning to end. Right as you pull in there is an ample amount of parking including a practice basket near the road.
The layout (with a map) seemed to flow fairly well and included both red and white tee boxes per hole (although we only played the further tee's - white). Each hole has a very unique feel, whether it be the strategic placement of the tee, pin, or the general layout.
Because the course is located on a flood plain the middle of the course tends to have a lot of sand which I preferred over dirt just because when it rains some the ground gets compacted rather then muddy making footing much easier.
The elevation whether it be slight or extreme played a major factor on the course. For example, at times it had players throwing off an elevated tee across the flood plain then again uphill to a pin nestled around a few trees on a boulder (hole #13) or shooting downward off of a steep cliff toward a ring of trees which heavily guards the pin (hole #11) making accuracey key to scoring low.
Like others stated, there was not a ton of distance, but enough to make it challening. Holes varied from low tunnel shots dead on to long tight doglegs both left and right. When throwning across the flood plain from the elevated tee's it was easy to throw massive hyzer and sidearm/anhyzer shots with hopes of parking it for a birdie.
Either between or after a round you can go to the next park over (Noel Booth Park) where you will find grassy areas to picnic or watch people playing baseball and soccer.
Cons:
There were some major factors that kept this from rating higher including the fact that it is located on a flood plain. The summer course that I played (original layout) can only be played for so long each year before several holes are cut out in the middle and the course gets adjusted. Although I hear it is great, it is a shame that it even has to happen.
The litter can be a problem as well. Since there are no garbage cans on the course and it is used frequently, the amount of foot traffic and therefore garbage outweighs the efforts of the local club to be kept up as well as it should be (please pick up after yourselves including you ciggarette butts and beer cans).
Locating pins at times was a challenge too. Because the north west tends to be a little grey at times it can be difficult to locate the pins from the box so I found myself having to walk down the fairway to find it. Something as simple as orange tape around the pole would go a long way and not be too much of an eye sore.
Tee boxes were interesting and for the most part in good shape. However, they were fairly short and the footing was carpet. Unless it is changed out regularly I could see this getting very moldy and smelling pretty funky quick. During the summer though it didn't seem to bother me as much since the weather was farily dry but in the winter and spring yikes!.
Last, tee signs at the kiosk, by the tee's, and after each hole letting you know where to go to next. The course had none of this making navigation for a first timere nearly impossible. I printed off a map and know that without it I wouldn't have been able to play.
Other Thoughts:
This course truly was the best overall course that I have played in Vancouver, B.C.
The locals were very friendly and it was very obvious to see how much work has gone in to making this course what it is. I felt very satisfied after playing a round here feeling like I got the whole experience and know that I will be back sooner then later. My hats off to the locals of Langley, keep it up!
