Big Sky is an unincorporated community and census-designated place (CDP) in Gallatin and Madison counties in southwestern Montana, United States. As of the 2020 census, it had a population of 3,591, up from 2,308 in 2010. It is 44 miles (71 km) by road southwest of Bozeman. The primary industry of the area is tourism.

## Geography

Big Sky is located along the western edge of Gallatin County and eastern edge of Madison County approximately midway between West Yellowstone and Bozeman on U.S. Highway 191 and 30 miles (48 km) from the northwestern border of Yellowstone National Park. It sits within the Madison Range, with elevations in the CDP ranging from 5,900 feet (1,800 m) in Gallatin Canyon along U.S. 191 to over 11,000 feet (3,400 m) at the summit of Lone Mountain.
The "Meadow" area of Big Sky lies in the eastern part of the CDP in an alpine valley formed during the Cretaceous period, at a base elevation of 6,200 feet (1,900 m). Initially called the "Gallatin Canyon Basin", the Meadow is braided with small rivers that channel mountain snow run-off. Fishing is permitted on all of these feeders of the Gallatin River. Two ponds are found on the Middle Fork of the Gallatin that bisects the Meadow, and fishing there is permitted for those 16 and younger. Since 1993, an innovative sewer system has protected the water in the area from sewage discharge. Several agencies, such as the Gallatin River Task Force, monitor the health of the rivers.
The "Mountain" area of Big Sky is west of the "Meadow" area at a base elevation of about 7,400 feet (2,300 m). The community had two large ski resorts in the "Mountain" area: Big Sky Resort and Moonlight Basin. In October 2013, these resorts merged: both are now managed by Big Sky Resort, and both are alpine ski and golf resorts. The combined terrain of the two resorts allows them to market themselves as the "Biggest Skiing in America", with over 5,800 acres (2,300 ha) of terrain. The Spanish Peaks Mountain Club is a ski and golf resort that has three chairlifts and 13 ski runs connecting it to Big Sky Resort at the base of Big Sky's Southern Comfort lift. Spanish Peaks is also now owned by Big Sky Resort, in collaboration with the Yellowstone Club. Another resort, Lone Mountain Ranch, is a Nordic ski and summer resort that professionally grooms over 75 kilometers of cross-country ski trails. Yellowstone Club, a private resort, is located to the south and adjacent to Big Sky Resort.
The "Canyon" area of Big Sky lies in the Gallatin Canyon in the northeast part of the CDP, along the Gallatin River, a favorite for whitewater rafters and kayakers. The river, named after Albert Gallatin who was the U.S. Secretary of the Treasury during the Lewis and Clark Expedition, is a Blue Ribbon trout stream that attracts fly-fishers from around the world. Several dude ranches (320 Guest Ranch, Elkhorn Ranch, Cinnamon Lodge and 9 Quarter Circle) operate in the Gallatin Canyon.
According to the U.S. Census Bureau, the CDP has a total area of 120.2 square miles (311.4 km$^2$), of which 120.0 square miles (310.8 km$^2$) are land and 0.2 square miles (0.6 km$^2$), or 0.18%, are water. Most of the CDP drains to the east into the Gallatin River, while the westernmost portions drain west via Cedar Creek and Jack Creek to the Madison River. The Gallatin and the Madison both drain north to form the Missouri River.

### Climate

This climatic region is typified by large seasonal temperature differences, with warm to hot summers and cold (sometimes severely cold) winters. According to the Köppen Climate Classification system, Big Sky has a borderline humid continental (Dfb) / alpine subarctic climate (Dfc). for most of the area, but the lower elevations may be closer to a dry continental climate.
