Pros:
The course makes excellent use of a hillside on the eastern edge of Queen Elizabeth park. With wonderful views of the Coast Range and downtown Vancouver to the north, this is one of the most pleasant places to hang out in this part of town. The atmosphere is casual, with low profile beer consumption and what-not. Hop over to Main St to the east and crawl through the pubs all the way north after a few rounds.
There are 9 holes, with backpads extending to 18. The course is very well-marked, and full of locals who've been playing it for decades...it is a treat to see their mastery of the course. Lots of long holes, big down hill drives, open fairways, big mature trees, and a water hazard make this a fun time by any measure.
Cons:
The course is somewhat small, and given Vancouver's rainy climate some holes become mudpits after long periods of rain. For tournaments the course is expanded into other parts of QE park, but apparently it is difficult to get a permanent installation in the other portions which would otherwise make this a world-class course.
Other Thoughts:
If you're in Vancouver, check it out. It is the city's greatest disc golf experience. There is a sporting goods store on Main and 33rd, called Abbie's, which has a full selection of discs and acts as a sort of pro shop for this course.
