Alaska: Gates of the Arctic National Park

This is the ultimate wilderness of Alaska’s arctic region. No roads, trails, or services are available in this northernmost national park in the United States, where visitors must fly or hike in to breach its boundaries. Endless summer nights transition to aurora-filled night skies in winter. Six wild rivers run through glacier-carved valleys, across the ageless and virtually unchanged park where humans and wild ecosystems have lived for thousands of years.
