About Denali

Summer's near-endless daylight rules out stargazing then, but the shoulder seasons and winter make Denali one of the best aurora-viewing national parks in the country.
What you can see in the sky
Aurora borealis on clear nights during the dark season, plus an exceptionally deep Milky Way given the Bortle 1 rating.
