Denali National Park

Denali, which means 'the high one' in the Koyukon Athabascan language, rises 18,000 feet from its base to summit — a vertical rise greater than Mount Everest. The mountain sits at the heart of the Alaska Range, a 600-mile arc of mountains and glaciers that includes dozens of peaks over 10,000 feet and some of the largest glaciers outside the polar regions; the Kahiltna Glacier alone is 44 miles long. The mountain was officially named Denali in 2015, restoring the name used by Alaska Natives for centuries, after decades of political dispute over the name 'Mount McKinley.' Climbing Denali is a serious mountaineering objective: roughly 1,000 climbers attempt the summit each year via the West Buttress Route, the most popular, which involves flown access to a base camp at 7,200 feet on the Kahiltna Glacier and ascent over several weeks with acclimatization. The success rate is about 50%, and the mountain has claimed over 100 lives. Even for non-climbers, the mountain's scale and its glacier-fed braided rivers that reshape the valleys each summer are defining features of the park's landscape. The park's geology is complex, with rocks from multiple terranes that were accreted to North America over millions of years, including the dramatic Polychrome Mountains, whose colorful bands of sedimentary rock give them their name.

Denali is one of the best places in North America to observe large mammals in their natural habitat. Grizzly bears are common in the tundra and willow areas, and bus riders along the park road frequently see them, particularly in summer when they forage on berries and roots. Dall sheep are often spotted on the high slopes above the road near Polychrome Pass and Igloo Creek. Moose, the largest member of the deer family, are common in the lowland spruce forest and wetlands, and bulls with full antlers are impressive in the fall rut. Caribou, part of the migratory Denali herd, move through the park seasonally, though their numbers have declined significantly in recent decades due to factors that are not fully understood. Wolves, the most elusive of the big five, are present in several packs within the park, and their howling can occasionally be heard from Wonder Lake. The park also supports golden eagles, gyrfalcons, and a rich diversity of smaller mammals, including arctic ground squirrels, hoary marmots, and lynx. Wildlife viewing is best done from the park's shuttle and tour buses, which travel the restricted road; the buses provide elevated vantage points and knowledgeable drivers, and passengers can get off and on buses to hike.

Denali's 92-mile road is the only road in the park, and private vehicles are restricted to the first 15 miles except with a special permit, so the only way to see most of the park is by bus. The park operates two types of buses: shuttle buses, which are less expensive and stop on request for wildlife sightings and hikers, and tour buses, which include narration and lunch. Shuttle buses run to several destinations along the road, including Toklat River (53 miles), Eielson Visitor Center (66 miles), Wonder Lake (85 miles), and Kantishna (92 miles), the former mining district at the road's end. The journey to Wonder Lake takes about 6 hours one way, and the full round trip is a long, tiring day, so many visitors break the trip with an overnight at one of the campgrounds or the Kantishna lodges. The road is narrow, mostly gravel, and crosses several mountain passes, and it is open only from late May to mid-September, weather permitting. Bus tickets should be reserved months in advance, as demand is high and seats are limited. Buses begin running at around 6 a.m. in summer, and early buses often have the best wildlife sightings and clearest views of Denali before afternoon clouds build.

Denali's backcountry is one of the few truly trailless wilderness areas in the National Park System. Backcountry hikers are required to obtain a permit at the Backcountry Desk and are assigned to specific 'units' — the park is divided into 87 management units, each with a daily quota. Within a unit, hikers make their own routes across tundra, gravel bars, and ridgelines, and are required to carry bear-proof food canisters and to know how to respond to bear encounters. River crossings are also a significant hazard, as glacial rivers are cold, fast, and change daily; crossing techniques and timing are critical. The park's short summer season runs from late May to mid-September, with peak visitation in July. June brings long daylight, with the sun barely setting, and August can bring rain and the first hints of fall color. Winter in Denali is extreme: temperatures regularly reach -30°F or lower, the park road is closed beyond the first few miles, and most facilities are shut. However, the park is open for cross-country skiing, dog sledding (the park maintains a historic kennel and offers demonstrations), and winter camping, and the northern lights are visible from September through April on clear nights. Advance planning is essential for any Denali visit, and flexibility is key, as weather can close roads and cancel buses for days.
