Kangerlussuaq, Greenland

Kangerlussuaq boasts the highest aurora-viewing reliability among clear-sky destinations, with 300 cloud-free nights annually — far outperforming #10 Churchill's typical 200. The stark Greenland ice cap eliminates light pollution entirely, offering unrivaled darkness. This former US Air Force base records an average temperature of -20°C during peak season, colder than the typical rival, but the payoff is a 90% probability of seeing auroral activity on any given winter night, a metric that beats all other entries on this list.
