The prominent physical feature of the county is the Gallatin River, named by Meriwether Lewis in 1805 for Albert Gallatin, U.S. Treasury Secretary from 1801-14. A small part of Yellowstone National Park lies in the southeastern portion of the county. The Big Sky Resort is about midway between West Yellowstone and Bozeman, though the ski area itself lies mostly in neighboring Madison County, Montana. The Gallatin River canyon is accessed by U.S. Highway 191. In the mid-19th century, a portion of Gallatin County was left over after the division of the Dakota Territory into other states. In 1873, the patch was attached to Montana and became part of Gallatin County. 
According to the U.S. Census Bureau, the county has a total area of 2,632 square miles (6,816.8 km2), of which 2,606 square miles (6,749.5 km2) is land and 26 square miles (67.3 km2) (0.99%) is water. The county attained its present boundaries in 1978, when the former Yellowstone National Park (part) county-equivalent was dissolved and apportioned between Gallatin County and Park County. Gallatin County received 99.155 square miles (256.8 km2) of land area and 0.119 square miles (0.3 km2) of water area, whereas Park County received 146.229 square miles (378.7 km2) of land area and 0.608 square miles (1.6 km2) of water area.
