Kluane National Park and Reserve
About 170 km (100 miles) west of Whitehorse, the reserve has millions of acres for hiking. This is a completely roadless wilderness, with hundreds of glaciers and so many mountains over 14,000 feet high that most of them haven't been named yet (one exception: Mt. Logan, Canada's highest peak). Kluane, the neighboring Wrangell–St. Elias National Park in Alaska, and a few smaller parks, constitute the largest protected wilderness in all North America. The staff at the Haines Junction visitor center can provide hiking, flightseeing, and other information. There's also the small Thechàl Dhâl Visitor Centre at the southern end of Kluane Lake whose staff can recommend hiking trails at numerous roadside pullouts that are great for Dall sheep viewing. If you're driving at sunrise or sunset from spring through fall, there's a good chance you'll catch sight of a grizzly bear eating roots or leaves near the side of the road.
