🏔️

Denali National Park · Bortle 1–2

North America's highest peak provides one of the most dramatic mountain foregrounds on earth under Bortle 1–2 sky. Wonder Lake in the park interior reflects Denali cleanly on calm nights. September is the optimal window — dark enough for Milky Way, galactic core still visible, aurora beginning, and fall colour on the tundra. Check tonight's sky →

🌋

Katmai National Park · Bortle 1

Remote wilderness on the Alaska Peninsula accessible only by floatplane. Bortle 1 sky over volcanic peaks and coastal landscape. Brown bears fishing at Brooks Falls make extraordinary foreground subjects in September when Milky Way is visible and bears are active. Check tonight's sky →

🌌

Wrangell-St. Elias National Park · Bortle 1

The largest national park in the US — six times the size of Yellowstone. Vast glaciated terrain, volcanic peaks, and abandoned copper mines as foreground under Bortle 1 sky. Accessible by road to Kennecott; deeper wilderness by small plane only. Check tonight's sky →

🛤️

Dalton Highway Corridor · Bortle 1

The road to the Arctic Ocean passes through some of the darkest terrain in North America. The Brooks Range crossing and Arctic tundra provide extraordinary foreground. Late September brings both Milky Way and aurora in the same frame at this latitude. Check tonight's sky →

🌊

Kachemak Bay / Homer Spit · Bortle 2–3

Homer on the Kenai Peninsula is one of Alaska's most accessible dark sky destinations. The spit juts into Kachemak Bay with the Kenai Mountains as backdrop. September through March delivers dark nights with both Milky Way and aurora opportunity. Check tonight's sky →

🏕️

Chena Hot Springs Area · Bortle 1–2

Northeast of Fairbanks under some of the darkest sky in interior Alaska. The hot springs allow outdoor soaking while watching aurora and Milky Way — a uniquely Alaskan experience. The aurora oval is directly overhead at this latitude in winter. Check tonight's sky →

Planning Tips for Alaska

Alaska's Milky Way window is September through April — the same window as aurora season. Unlike the lower 48, Alaska's summer is white nights, not Milky Way season. Target September and October for the galactic core still visible at reasonable hours alongside early aurora. February and March offer long dark nights with the Milky Way in a different orientation.
