# Denali National Park

Region: Interior AK, Ontario, Canada
Coordinates: 63.1148, -151.1926
Bortle class: 1 (1 = pristine, 9 = inner city)
Drive from Toronto: Along the Parks Highway in interior Alaska, about 2.5 hours south of Fairbanks or 4.5 hours north of Anchorage by road.
Best time: Late August through April, when nights are dark enough for aurora viewing — Alaska's summer midnight sun makes stargazing impossible in June and July.

## Overview
Denali is rated Bortle Class 1 — as dark as skies get — and its far-northern latitude means long, aurora-friendly nights from late August through April. 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 to see
Aurora borealis on clear nights during the dark season, plus an exceptionally deep Milky Way given the Bortle 1 rating.

## Highlights
- Rated Bortle Class 1 — among the darkest skies measured anywhere
- One of the most accessible national parks in Alaska for aurora viewing
- Denali's summit and surrounding tundra offer huge open horizons

## Tips
- Aurora viewing takes patience and luck — check the geomagnetic (Kp) forecast
- No stargazing is possible during Alaska's summer midnight-sun months
- Winter travel requires serious cold-weather preparation; temperatures can reach -40°F
