Boone County

Established in 1846, Boone County grew from prairie and river-valley settlements into a central Iowa county shaped by agriculture, rail transportation, coal-era communities, and regional trade. Boone became the county seat and a major railroad center, while Madrid developed a distinct mining and immigrant history. Today the county’s identity still connects working landscapes with historic downtowns, heritage rail, the Des Moines River, and enduring community institutions.

Boone County is easy to explore in layers. Spend a morning in downtown Boone, ride the Boone & Scenic Valley Railroad, then head south toward Ledges State Park or the High Trestle Trail near Madrid. Ogden offers a classic small-town stop and access to county recreation areas. Across the county, parks, libraries, museums, restaurants, seasonal festivals, farms, and outdoor recreation give visitors plenty of reasons to slow down and stay awhile.
