Mount Hayes, Denali Highway, Alaska

Cutting across Alaska’s interior connecting the towns of Paxson and Cantwell, the Denali Highway is one of the 49th State’s best road trips. Highlights of the Denali Highway of course are the epic mountain views of both the Alaska Range and the Wrangell St. Elias Range. 

The Denali Highway is only maintained from May to October each year, making it impassible by car through much of the winter due to snow levels once the interior gets snowed in for the year. 

It is also important to note that the Denali Highway is not the same road as the Denali National Park Road. The Denali Highway does not enter the national park. 

Denali Highway History

Also known as Alaska Route 8, the Denali Highway officially opened in 1957 giving access to Denali National Park from the Glenn Highway. Most people these days would access Denali National Park from the Parks Highway, which wasn’t built until 1971. 

The Best Time of Year to Drive the Denali Highway 

The best months to take on a road trip down the Denali Highway is from mid-June through mid-September. Of course, the road is maintained from May to October but at the beginning and end of that time, the roads can be impassible at times if the weather is bad. 

To see road conditions check out the Alaska 511 website or you can call them by dialing 511 if you are in Alaska or 866-282-7577 if you are outside of Alaska.

Rental Cars & Vehicles on the Denali Highway

At 134 miles in length, the Denali Highway is an almost entirely dirt road with just a small section of it being paved on both ends. This is an important fact to note as many rental car companies will not allow their vehicles to be driven off of paved roads. 

Before taking on the Denali Highway it would be wise to check and see if your rental contract will allow for it. In this case, I would recommend Alaska 4×4 Rentals as they do allow their cars on dirt roads. 

How Bad of Conditions is the Denali Highway in?

This can differ from year to year as the Denali Highway is somewhat remote and maintenance is hit and miss. If you happen to travel the Denali Highway on a year where it has been recently worked on then chances are the road can be in decent condition.

You’ll likely find that there are sections of the road that are smooth sailing and other sections where it is rutted out and littered with potholes. You’ll want to drive carefully to avoid any damage to your car.

Tips & Important Info for Driving the Denali Highway

  • Bring at least one spare tire with you. It’s not unheard of to get flats along the route owing to sections in poor conditions.
  • Make sure and either fill up with gas in Glennallen or Cantwell depending on the direction you take.
  • There are few services along the highway. The Maclaren Lodge offers limited services including vehicle repair and has a restaurant.
  • The Denali Highway is only paved on the first 21 miles in from Paxson and the first 3 miles in from Cantwell, otherwise, it’s entirely dirt.
  • You can camp pretty much anywhere along the Denali Highway unless it’s private property. There are heaps of pull-offs along the route perfect for camping.
  • There are also two maintained BLM campgrounds along the way. 
  • There are 5 lodges along the Denali Highway for those that don’t want to camp.
  • You can drive the entire route in a single day if you are pressed for time, but it’s best to allot at least one overnight, if not more.
  • Driving the Denali Highway in either direction will give epic views, but most opt to drive it from Paxson to Cantwell.
  • Yes, it is possible to see the northern lights along the Denali Highway in early May, late August, and September if you get lucky.
  • You can travel along the route in the winter months after the highway is snowed over but it’ll be by snowmachine (snowmobile) or dog sled. 

Camping Along the Denali Highway

Mount Hayes, Denali Highway, Alaska

Points of Interest Along the Denali Highway

The Denali Highway is littered with points of interest, scenic viewpoints, and adventure. The following is a comprehensive list of the most well-known and scenic stops along the way.

Tangle Lakes Archeological District, Denali Highway, Alaska

Tangle River Inn: Milepost 20

Look for the giant sign that says PIZZA! and you’ve arrived at Tangle River Inn. Built in 1953, this homestead turned into rooms and cabins for rent. Like the sign suggests you can get a hot pizza here, but also you can rent a canoe to paddle around Tangle Lakes in. 

Pavement Ends: Milepost 21

Wave goodbye to the smooth asphalt for the next 110 miles, the road goes to dirt starting here at milepost 21.

Rock Creek Bridge & South Landmark Gap Trail: Milepost 24.7

Just a hair further will bring you to the South Landmark Gap Trail which gives access to a scenic 5 mile hike to a viewpoint for Tangle Lakes or an 8 mile hike to the southeast to reach Osar Lake (mud boots recommended for the South Landmark Gap Trail!).

Maclaren Summit, Denali Highway, Alaska

As you make your way up to Maclaren Summit, you’ll pass the main trailhead for Osar Lake, a trail that will take you along eskers in the tundra. Eskers are large ridges of stratified sand and gravel left behind in once glaciated areas. 

Atop Maclaren Summit, you’ll be on Alaska’s second highest highway pass at 4,086 feet in elevation. It is signposted and the viewpoint offers sweeping views of the Maclaren River and Alaska Range. From the summit, you will also find the 3 mile out and back Maclaren Trail.

Thermokarsts, Palsas & Kettle Lakes: Milepost 41

Here at milepost 41, you can view the interesting subpolar features of thermokarsts and palsas.

A palsa is a frost-heave found in polar and subpolar regions that contain permafrost ice lenses. An ice lens is a localized accumulation of ice formed when moisture, diffuses within soil or rock.

Thermokarsts are sinkholes formed by the melting of the ice within the palsa’s ice lens in these permafrost systems. Some thermokarsts will eventually fill with water and form lakes, which can be seen here at Kettle Lakes which are technically thermokarsts.

Maclaren River, Maclaren Bridge & Maclaren Lodge: Milepost 42

At milepost 42 of the Denali Highway, cross over the Maclaren River bridge to the other side to reach the Maclaren River Lodge. At the lodge, there is a full-service restaurant serving breakfast, lunch, and dinner, and rents out cabins. The lodge also rents out canoes, can arrange various day trips, and even offers up firewood and tire repair services. 

Just beyond the Maclaren River Lodge, you’ll reach a scenic viewpoint pull-off with views of the Maclaren Glacier in the distance. 

Maclaren River Trail: Milepost 43

Maclaren River & Glacier, Denali Highway, Alaska

The Maclaren River Trailhead gives access to both Hidden Lake and Maclaren Glacier. Hidden Lake is a 10 mile journey each way, whereas Maclaren River is a 16 mile jaunt. 

Crazy Notch: Milepost 46

Crazy Notch is a geological feature that the Denali Highway passes through at milepost 46, carved into the Earth by the Maclaren Glacier long ago leaving high glacial moraines on either side of it. The notch was carved even deeper by a creek that formed.

It’s not uncommon for this area of the Denali Highway to be impassible in late spring and fall due to snow drifts that accumulate here. Just beyond passing through Crazy Notch at milepost 47, you’ll pass Mile Lake just off the side of the road.
