There are no guarantees the northern lights will start dancing on the night you look skyward, but it's so worth taking the chance. One of the great rewards for hanging out in Alaska once the dark and cold settle over the state, the northern lights (or if you want to be scientific about it, aurora borealis) serve up a light show that is equal parts science, magic, and art. Your best bet for catching the light show is to head away from city lights. That’s one of many reasons it’s worth making the trip to Denali National Park, open year-round. When the park’s summer crowds disappear, visitors feel as though the massive national park is an intimate personal space.
