Finnish Lapland holds the aurora oval over Rovaniemi (the official Santa village), Levi and Saariselkä's reindeer-pulled tracks, and Inari's Sami cultural heart 250km north of the Arctic Circle.
Polar night at Saariselkä for two weeks around solstice, Levi ski resort runs December-May, and aurora most active September-March on dark clear nights.
Ruska autumn colour explodes across the fells, aurora season beginning, and the reindeer round-up corrals fill across Inari and Sodankylä.
Midnight sun above the Arctic Circle for two months, Sodankylä Film Festival in mid-June with 24-hour screenings, and Pallas-Yllästunturi hiking peaks.
Spring backcountry skiing in long daylight (kelvarpäivät), Levi season closing, and the Sami reindeer migration moving toward summer pastures.
