San Carlos is a settlement in northwestern East Falkland, lying south of Port San Carlos on San Carlos Water. It is sometimes nicknamed "JB" after a former owner, Jack Bonner.
The settlement consists of a number of properties including a dwelling with a small cafe which also provides craft facilities. As noted in the history section, there is a small museum that pays homage to the Falklands Conflict as well as local nature and culture.
