Pros:
This course incorporates many different situations. Tight treed holes, long open holes, doglegs left and right, and it also has nice use of elevation change. Hole # 14 was pretty cool, it was only about 150 feet but the hole was about 50 feet above the tee. The course has dual tees which adds some variation. The extra set of tees are sometimes longer and sometimes a similar distance with completely different line to the hole.
Cons:
Tee pads are very short and don't allow up run up on some holes. Course is hard to follow if you don't have a map. Looks like people use the gravel area for fires at night so there are a few burn scars.
In terms of facilities, the course has none. You'll have to pack out any garbage you have, there's no signs either.
The other thing preventing this course from getting a higher mark is the lack of distance. There are maybe two or three holes where you can break out the big guns but the rest are fairly short par threes.
Other Thoughts:
This is bar none, the most fun course I've played in the Vancouver area. Bring a map and you'll have no problems navigating the course. Every hole offers something new and I can't wait to go back and play this course again.
UPDATE: I've heard rumblings that the City of Langley may be installing a new DG course soon. I will report back as soon as further details become available to me.
