Pros:
This course is built utilizing winding, hilly cross country ski trails that have been carved out of the coniferous forest. It's as good a setting for disc golf as I've ever seen.
The fairways are plenty wide that they don't feel like "tunnel shots" (with maybe 1 exception), usually 30-50 ft wide I think, but straying from that fairway will certainly be penalized by the trees. When you find yourself in the trees, sometimes you can play straight to the basket with a careful straight, maybe overhand shot, and sometimes it's too thick forcing you to retreat back to the fairway... it varies as the density of the forest varies.
The best part, for me, is the vertical changes. You get to throw shots here that go down hill 100+ ft, or uphill 50+ft, and across an open valley. It really makes for an interesting game that can be very rewarding when you get dialed in. Make no mistake, it's a REALLY challenging course, but that just makes your good shots that much more rewarding.
And obviously this being in the Rockies, you'll get beautiful views, creeks, wildlife, etc. There are washrooms at the start of the course, a practice hole, and the holes are well marked and everything in good condition.
Cons:
The baskets aren't great, and the natural tee pads are not in good shape, some either frequently muddy or awkward with roots and such in the way.
If you're off your game and throwing a bit wild, this course could get frustrating. I went higher above par here than I ever have anywhere else... but I still had fun.
You're in the mountains here so the weather can change quickly and you're going to want to bring a jacket and maybe mosquito repellent in the spring.
Lost discs are a possibility here if you get deep in the trees, but it's not horrible as generally the ground cover isn't that thick save for some areas near the creeks.
Other Thoughts:
I think everyone in Alberta knows this is a must play course, which is why the Ace Race held here is one of the biggest in the world.
If you are a disc golfer who find yourself in Calgary, you should be making a trip out to Canmore/Banff anyway, but make a round of 18 holes at this course part of that. It's worth the hour drive out from Calgary just for the disc golf.
