Plan a trip to Boise
Founded in 1864, a few years after gold was discovered in the Idaho City basin, Boise derives from the French word "le bois", for the beautiful woodlands that surround the Boise River. Grab a bike or some walking shoes and explore tree-lined pathways of the 25-mile Boise River Greenbelt. Visit the enriching Basque museum and cultural center downtown, which showcases the Spanish Basque immigrant population that settled in Boise. Drive a little way out of town for a wine flight with some artisan cheese and elk salami at 3 Horse Ranch Vineyards.
