Denali Highway — Paxson to Cantwell via the Alaska Range Tundra Corridor

The Denali Highway was Alaska’s only route to Denali National Park from 1957 until 1972, when the Parks Highway opened and traffic quietly abandoned it. That neglect is its greatest asset. Running 134 miles of gravel between Paxson on the Richardson Highway and Cantwell on the Parks Highway, the road traverses open tundra, braided glacial rivers, and high alpine benches with unobstructed views of the Alaska Range that you will not find anywhere else at this elevation without a bush plane. Maclaren Summit, at roughly 4,086 feet, is the high point — on a clear day the entire massif from Hayes to Denali fills the western horizon. Ptarmigan flush from the willows, grizzly bears work the berry patches in August, and the fall colour in mid-September turns the tundra into a fire you drive through for hours.

The road is mostly graded gravel with some washboard and soft spots after rain; a high-clearance 4WD is strongly recommended though not always strictly required in dry conditions. The western third near Cantwell runs rougher and wetter than the eastern half. Fuel is available at Paxson and Cantwell — nowhere in between, so carry extra. Cell service is nonexistent. The highway is officially open from snowmelt (typically late May) through October; snowmobilers own it the rest of the year. No permit required. Dispersed camping is legal and stunning at nearly every pullout.
