South Fork is a statutory town in Rio Grande County, Colorado, United States.

[7] South Fork was founded in 1882, by which date its location was already marked by the presence of a coaching post, dating from the construction of the railroad connection of the Rio Grande Western Railroad line to Creede, which had been built to support the Creede silver mine.

Originally the principal economic activities involved forestry and mining, but in recent decades these have been overtaken in the employment statistics by tourism.

This was in response to a local farmer's market in which one of its vendors was asking people for donations to the Black Lives Matter movement and the NAACP.

[8] South Fork's Riverbend Resort was the filming location of fictional 'Kamp Komfort' in the 1983 hit movie National Lampoon's Vacation.
