Glen Park is a district slightly to the north-east of the city centre of Los SantosSan Andreas. It is based on MacArthur Park and Echo Park . The district is quite rich and middle-class even though there is severe gang activity and drug trafficking. Glen Park is controlled by the Ballas gang in the early part of 1992, and is close to other Ballas controlled districts, namely Jefferson and Idlewood. It is later controlled by the Grove Street Families. Besides the two aforementioned districts, nearby areas include Downtown Los Santos, the Mulholland Intersection and the Los Santos Vagos-controlled Las Colinas. There are two known residents: Mark "B Dup" Wayne and Barry "Big Bear" Thorne, who moved to Glen Park from Ganton. Little Weasel, a Ballas gang member, may also live in Glen Park. Glen Park has a population of 241 as of 1992, being one of the most densely populated neighbourhoods as of its size. Glen Park is mixed race.
Glen Park consists of many single-family homes, apartments, a skatepark and a large palm-tree dominated parkland area with a central pond and overpass bridge. The nearby County General Hospital can also be found despite being located in the official zone of Jefferson.
