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 more than 14,000 feet high that most of them haven't been named yet. 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. Visitor center, 119 Logan St., Haines Junction, Yukon, Y0B 1L0. 867/634–7207; www.pc.gc.ca.

On request, the society can put together kid-friendly hikes. 302 Hawkins St., Whitehorse, Yukon, Y1A1X6. 867/668–5678; www.yukonconservation.org.
