National Park of Denali

Location: Alaska
Established: February 26, 1917
Size: 6,075,029 acres (2,458,477 hectares)

On any summer day in Denali, Alaska's most well known national park, hundreds of people see sights that will stay with them the rest of their lives. Perhaps a golden eagle will soar off the cliffs at Polychrome Pass, or 20 Dall's sheep will rest on a green shoulder of Primrose Ridge, or a grizzly will ramble over the tundra at Sable Pass. Maybe a caribou will pause on a ridgetop, silhouetted by the warm light of day's end, or a loon will call across Wonder Lake, or clouds will part to reveal the great massif of Mount McKinley, 20,320 feet (6,194 meters) high, the roof of North America.

The drama is always there. To see it, all you need to do is travel the 92-mile (148-kilometer) park road. The farther you go, the more you'll see, for the subarctic landscape will open up as big as the sky and the animals will move through it with wild, ancient poetry.

Other North American parks have their wildlife, but none has animals so visible or diverse as Denali. And other parks have their mountains, but none with a stature so stunning, a summit so towering as McKinley.

Denali's visitors have increased almost 200 percent in 30 years. Accommodating them without eroding the park's wilderness has been a struggle. A bus system that permits maximum wildlife viewing while holding down traffic has been designed. Campgrounds are modest and unobtrusive. And the wilderness areas have strict overnight camping ceilings to prevent overcrowding and damage to the flora and fauna. Unless you plan ahead by using the park's easy-to-use reservation system, you may have to wait a day or two to get your preferred campsite or bus reservation.
