About Boise
Boise has gone from regional secret to Condé Nast and Outdoor Magazine darling in just a few years — a compact, walkable downtown, extraordinary river access (you can float the Boise River through downtown), and within 2 hours of hot springs, ski resorts, whitewater, and some of the best fly-fishing in the West. It remains genuinely affordable compared to Denver and Seattle.
Visa: Domestic — no travel documents required.
