There is some cliff jumping in Whistler, and it is into the coldest of the lakes. That being said, the cliffs are nice sized with some enjoyable 40 footers and some other smaller ones and larger ones. It is definitely a weird to drive here. To get here, drive north towards Pemberton from Squamish, cross at the first steel bridge over the river (if you hit wedgemount, you`ve gone too far) and turn south along the logging road. Drive to the end where there is a big lot and the road goes no further. Now you walk about 1 km down the train tracks and look for the lake. Its really nice here, I haven`t been in many years, but it was great last time with blackberries and strawberries growing naturally along the train tracks. Check out the video to see my boy, Austin Ross, set up a trampoline on the cliffs here.
