Sweden
A rain-shadow valley whose famously clear Arctic sky draws the aurora hunters north.
The mountains above Abisko catch the clouds before they reach the valley, leaving some of Sweden's clearest, driest sky — which is why aurora hunters rate the valley among their best odds anywhere, though the lights keep their own counsel. In summer the midnight sun floods the same valley in twenty-four-hour gold.
Abisko National Park spreads from the end of Torneträsk, one of Sweden's largest lakes, in the rain shadow of the border mountains — the driest corner of the country, which is exactly why aurora-hunters rate its odds so highly — clear nights come more often here, and still promise nothing. The Kungsleden trail starts here, striking south through Arctic tundra toward Kebnekaise, and the Swedish Tourist Association's mountain station has anchored the trailhead since the early 1900s. The birch forest turns gold in September, the first snow follows within weeks, and the Abiskojåkka canyon cuts green-blue through its very middle. Small park, enormous sky.
Solo
The Kungsleden runs south from the door through wilderness vast enough to swallow the trail's whole length — and the trailhead's century-old station anchors the start.
Couple
Aurora over the valley when the sky allows, and the hush of the polar night — Abisko turns winter darkness into the point of the trip.
Friends
River crossings, route calls and mountain-station evenings — the classic group trek starts at this trailhead.
