Lago Zancudo is an undeveloped wetland located next to the Zancudo River south of Fort Zancudo in Los Santos County, San Andreas appearing in Grand Theft Auto V and Grand Theft Auto Online. Lago Zancudo was once a jetty used for trading before being given to the state of San Andreas in 1941. Lago Zancudo was eventually returned to its natural state and became the home of a number of animals including brown bears, beavers, coyotes, deer and cranes, although only cranes and deer can be seen in the area.
- A letter scrap can be found in Lago Zancudo.
- If the protagonist of GTA Online is killed near Fort Zancudo, they will respawn at Lago Zancudo.
