Adams County

Adams County is an administrative division in western Idaho's mountainous region covering approximately 3,500 square kilometers of forested areas and river valleys. The county seat of Council serves as its main hub, housing government offices and community facilities.

The county was officially established on March 3, 1911, and named after John Adams, the second US president. Its creation followed the expansion of settlements in western Idaho during the early 20th century.

The communities here celebrate their heritage through local gatherings and craft markets that blend Native American traditions with settler history. Visitors can experience how residents maintain these cultural connections in their daily lives and events.

The county is best explored by car as roads wind through mountains and valleys with considerable distances between communities. Visitors should check local road conditions and allow extra time for travel between settlements.

While twelve counties across the United States share this name, this region stands out for being one of Idaho's most sparsely populated areas. The combination of low population density and natural resources gives the county its particular character.
