Boise County is a rural mountain county in the U.S. state of Idaho. The population was 7,028 at the 2010 census, up from 6,670 in 2000. The county seat is Idaho City, and Horseshoe Bend is its largest city.
The Bogus Basin ski area is in the southwestern part of the county. The county's eastern area contains the central section of the Sawtooth Wilderness, the western part of the Sawtooth National Recreation Area.
The county was established February 4, 1864, with its county seat at Idaho City. It was named for the Boise River, which was named by French-Canadian explorers and trappers for the great variety of trees growing along its banks in the lower desert valley. The Boise Basin, in which Idaho City lies, was one of the richest gold mining districts in the nation. Gold was discovered in 1862 and more of it was pulled from present-day Boise County than from the entire state of Alaska. At its peak in the mid-1860s, Idaho City was the largest city in the Northwest, and it was this rapid population influx that lead to the establishment of the Idaho Territory in 1863. The lower elevation communities of Horseshoe Bend (Payette River) and Boise (Boise River) were staging areas for the Boise Basin mines.
According to the 2000 census, the county has a total area of 1,906.76 square miles (4,938.5 km2), of which 1,902.46 square miles (4,927.3 km2) (or 99.77%) is land and 4.30 square miles (11.1 km2) (or 0.23%) is water. The highest point in the county is Thompson Peak at 10,751 feet (3,277 m), on its eastern border in the Sawtooth Wilderness. The county's lowest point is on the Payette River, on its western border with Gem County, at approximately 2,500 feet (762 m).
