Big Sky is an unincorporated community and census-designated place (CDP) in Gallatin and Madison counties in southwestern Montana, United States.

[5] 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.

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.

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.

Spanish Peaks is also now owned by Big Sky Resort, in collaboration with the Yellowstone Club.

The river, named after Albert Gallatin[6] 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.

Elk, deer, black bears, grizzlies, upland birds, waterfowl, and wolves call this area home.

Hunting is prohibited in Big Sky proper, but it is permitted throughout the National Forests that surround the area.

The museum displays artifacts, photographs and documents, along with extensive information about the pioneer Crail and Creek families.
