First off seeing as you will make your way up to whistler all the courses are worth playing up there. Personally my favorite is big sky in Pemberton which is 20-30 outside of whistler but they are all worth playing. If you do decide to go from Vancouver out to Calgary there is some extremely good golf courses on the way. Some suggestions of places to look into: Tobiano, predator ridge, grey wolf, and Banff springs. There are many others but those are a few of the top ones along the way.
