The Denali Highway
More of a dirt road than a highway, the 135-mile Denali Highway opened in 1957 as the first road to access Denali National Park (today, it doesn't go into the park) and cuts through some of Alaska's most dramatic and isolated alpine terrain. Only 24-miles of the highway have been paved and the going is often rough and slow on this poorly maintained road. With plentiful roadside camping, expansive views of three different mountain ranges (The Alaska Range, Chugach and Wrangell Mountains) during clear weather and clocking in as the second highest road in Alaska where it crosses Maclaren Summit, driving the length of the Denali highway is an adventure onto itself — but also access to some of the most remote parts of the Alaska Range. If you're looking for something even wilder, try the Denali highway in the winter months, when access is restricted to dog sleds and snowmobiles.
