No matter whether you visit on foot, bike, or bus, you'll want to utilize the Denali road system as much as possible. Personal vehicles are only allowed the first 15 miles of the 92-mile long road, and most of the best potential views and wildlife are beyond this 15-mile marker. The view from the Eielson Visitor Center and Wonder Lake are the park's most iconic and these are located at miles 66 and 85, respectively.
But amazing views of the rolling tundra, foothills, and grizzly bears can be had almost anywhere. Take your time and if possible, spend multiple days either taking bus tours, hiking, or biking through the park to give yourself the best chance of an unforgettable view or wildlife encounter.
While the park is never technically closed, much of the road is snowed in during the winter months. Depending on the snowfall, travel along the park road can be hampered in spring and fall as well. The road is generally open up to Mountain Vista (mile 13) by mid-February. Check the park's website before visiting to stay up-to-date on any road closures.
