About Nahanni
Nahanni National Park Reserve is one of the most remote and least light-polluted places in Canada — there are no public roads in, and access is by floatplane or a long river or hiking trip only. That isolation is exactly what makes its night sky, and its aurora, so intense for the relatively few visitors who make it there.
What you can see in the sky
Aurora over the South Nahanni canyons, and an exceptionally deep, unpolluted Milky Way.
Best time of year
Late August through September, on river or canoe expeditions, when nights are dark and aurora activity picks up at this high latitude.
Why this site is worth the drive
No road access at all — among the darkest, least-visited skies in Canada
UNESCO World Heritage wilderness centred on the South Nahanni River
High-latitude location makes aurora sightings common on clear nights
Practical tips for Nahanni
