Denali Highway (AK)
The Road: The Denali Highway, also known as Alaska Route 8, is actually east in Denali Park, following the Alaska Range as it runs toward the Yukon. The road comprises two lanes and 135 miles linking the Richardson and Parks Highways.
The Ride: Raw natural beauty that starts with 21 miles of partially paved road, followed by a ribbon of pothole-ridden washboard surfaces, scores of potential roadkill (and, when the season is right, hunters), and awe-inspiring views of glaciers and peaks.
When To Go: Aside from the obvious weather constraints of this stretch, which includes the second highest pass in Alaska (with a 4,086-foot summit), riders should check the web for road closures, which are frequent and unpredictable.
