Denali Highway (Alaska Route 8) is a lightly traveled, mostly gravel highway in the Parks Highway. Opened in 1957, it was the first road access to Denali National Park (then known as Mount McKinley National Park). Since 1971, primary park access has been via the Parks Highway, which incorporated a section of the Denali Highway from Cantwell to the present-day park entrance. The Denali Highway is 135 miles (217 km) in length.

The highway is now little used and poorly maintained, and closed to all traffic from October to mid-May each year.[3] Only the easternmost 21.3 miles (34.3 km) and westernmost 2.6 miles (4.2 km) are paved; whether the remainder should be paved as well is a continual source of debate. Washboarding and extreme dust are common, the recommended speed limit is 30 mph (48 km/h).

Route description

The Denali Highway as seen in summer.

Traveling west, the Denali Highway leaves the Richardson Highway (Alaska Route 4) at Paxson, and climbs steeply up into the foothills of the central Alaska Range. The first 21 miles (34 km), to Tangle Lakes, are paved. Along its length, the highway passes through three of the principal river drainages in Interior Alaska: the Copper River drainage, the Tanana/Yukon drainage and the Susitna drainage. Along the way, in good weather, there are stunning views of the peaks and glaciers of the central Alaska Range, including Mount Hayes (13,700 ft), Mount Hess (11,940 ft) and Mount Deborah (12,688 ft). At MP 15, from the pullout on the south side of the road, in clear weather you can see the Wrangell Mountains, the Chugach Mountains and the Alaska Range.

The first 45 miles (72 km) winds through the George Parks Highway (Alaska #3).


There are developed campgrounds at Tangle Lakes (MP 22) and Brushkana Creek (MP 104), but there are dozens of pullouts where one can camp on public lands.

Services are scant along this road.

Year-round operations include Denali Highway Cabins & Tours (MP 0.2), Maclaren River Lodge (MP 42), Alpine Creek Lodge (MP68) and Backwoods Lodge (MP134); summer-only operations include Tangle Lakes Lodge (MP 22), Tangle River Inn (MP 20), Gracious House (MP 82). Winter travel on the Denali Highway is exclusively by snowmobile and dogsled. Automobile travelers are severely discouraged from attempting to traverse the road in winter; as recently as 1996 three persons died from exposure when snows blocked their progress. The road is cleared by DOT late in April and generally is passable by non-4WD from then until the first snows close it, usually late September on the eastern, tundra end and late October-early November on the lower, boreal forest western end.

The Tangle Lakes constitute the headwaters of the Delta River, a popular destination for canoeists as it is the launch point of the Delta River Canoe Trail.[4]

The Denali Highway is an important birding destination. It offers road access to alpine terrain – not that common in Alaska – and, in the brief birding season there, good viewing of a number of alpine breeders, including Arctic Warbler, Smith's Longspur, Long-tailed Jaeger, Whimbrel, Surfbird, Lapland Longspur, Horned Lark, Short-eared Owl, Wandering Tattler, Gyrfalcon and much more. A walk north along BLM's Maclaren Summit Trail (MP 39) can be very productive. There are also trumpeter swans and various other waterfowl in the lakes and ponds along the route.

Fishing for grayling and lake trout is decent, if not spectacular, in any of the clear water (i.e., unglaciated) streams.

Because the area is hunted heavily, larger mammals are much less common than in Denali National Park, but moose, grizzly bear, and caribou are fairly common. The Nelchina caribou herd, approximately 36,000 animals as of winter 2009–2010, normally passes through this area after calving season ends, and some autumns and winters as many as 16,000 animals can be seen at once. The herd forms an important foodsource for many residents of southcentral Alaska, and visitors eager to view the animals may be competing with hunters. The many lakes along the road are also a destination for duck hunting in the fall.

Most of the land along the highway is publicly owned. There are several BLM-maintained trails, and dozens of informal trails. This is a stretch of wild Alaska that is pretty much unspoiled, relatively accessible and beautiful.
