The main feature of the neighborhood is a small canal, and, referencing the name, suggests that it is used as a marina. The canal eventually flows into the sea. There are numerous businesses and residences, making it an ideal place to live in. Marina is not controlled by any Los Santos-based gang, although surrounding districts like Santa Maria Beach and Verona Beach have prominent gang activity.
Besides Santa Maria Beach and Verona Beach, the commercial districts of Vinewood, Market, and Rodeo also envelop the area.
