Denali Highway
Alaska's wilderness highway through caribou country
The Denali Highway runs 135 miles between Paxson and Cantwell, crossing the heart of Alaska Range country on what was the only route to Denali National Park before the Parks Highway existed. Built in 1957, this mostly gravel road climbs through alpine tundra at 2,400 feet elevation with jaw-dropping views of Denali itself on clear days. The Susitna River crossing at Mile 79 and the climb over Maclaren Summit at Mile 37 are the major waypoints, but the real attraction is the endless expanse of caribou country stretching to every horizon.
This is a moderate overland route suitable for any high-clearance vehicle, though the washboard sections will rattle your teeth loose. Summer is the only season—snow closes the road October through May. No permits required, but fuel up in Paxson or Cantwell as there’s nothing in between except a seasonal lodge at Maclaren River. Dispersed camping is excellent anywhere off the road. You’re driving through some of Alaska’s most pristine wilderness, with grizzlies, caribou, and wolves as your only company.

Frequently asked questions
Can a stock 2WD truck handle the Denali Highway, or do I need 4WD?
A high-clearance 2WD truck or SUV can handle it in dry summer conditions — the road is maintained gravel, not technical terrain. 4WD becomes useful if you hit wet sections or want to explore side spurs, but it's not required for the main route.
When does the Denali Highway open and close each year?
Typically opens in late May or early June and closes in mid-October, depending on snow. The sweet spot is July through August — snow is gone, the road is drier, and caribou migrations are active. Early June can still have snow and muddy stretches that will humble a 2WD rig.
Do I need a permit to drive or camp on the Denali Highway?
No permit required to drive the road. Dispersed camping along the corridor is free and allowed without a permit on state land — just camp at least 100 feet from the road and any water sources. No fees, no reservations.
What's the hardest part of the drive and what should I actually expect?
There's no single brutal choke point — the challenge is cumulative. Washboard, sharp gravel that eats tires, creek crossings that vary with rainfall, and 135 miles of absolutely zero services between Paxson and Cantwell. Carry two full-size spares and know how to change them.
How much fuel do I need to carry, and is there any gas along the route?
There is zero fuel on the highway itself — 135 miles with nothing between Paxson on the east end and Cantwell on the west. Fill up completely before entering and calculate your range honestly, factoring in idle time and rough road fuel burn. Most rigs should carry supplemental fuel in a jerry can.
