Whistler is a beautiful place in Winter to go skiing and enjoy all the activities available to Winter bunnies. But people often don't realise it is a magic spot in Summer also. I particularly recommend the bike riding. Lots of fun to be had and I don't mean hard core Mountain Biking, I mean sedate ride along quite flat roads and paths, kinda biking. You can rent bikes at Whistler for an hour or more and it is a great family activity also.
