Take a guided treetop eco tour through Whistler’s ancient coastal temperate rainforest with Ziptrek. On the fun, family-friendly Sasqatch tour, you’ll zoom down an exhilarating 7,000-foot zipline—the longest in the U.S. and Canada. After launching from Blackcomb Mountain, you'll reach speeds of more than 60 miles an hour. The 90-minute tour also takes you for a walk through the trees on swaying boardwalks and teaches you about Whistler’s super-sustainable village plan. You may even be lucky enough to spot bears who live in the pristine mountains and forests, which haven't been touched since the last ice age.
