Bonneville County, Idaho
Bonneville County is the urban hub of eastern Idaho, anchored by Idaho Falls. The Snake River runs through the city, creating a scenic greenbelt around its famous waterfall. With its convenient location, Idaho Falls also serves as a popular jumping-off point for trips to Yellowstone National Park.
The nearby Idaho National Laboratory brings a highly educated workforce to the region, creating a distinctive mix of cowboy culture and high-tech jobs. The county stretches from productive farmland to rugged mountain peaks, with plenty of opportunities for outdoor recreation, including skiing at Kelly Canyon, fishing along the South Fork, and hiking in the Caribou-Targhee National Forest.
Agriculture remains important in the rural parts of Bonneville County, with potatoes still playing a major role. The area also has a strong Mormon cultural influence, reflected in family-oriented communities and relatively few bars. Meanwhile, Idaho Falls is growing rapidly, with new subdivisions and development spreading across the surrounding countryside.
