The lighthouse is located on the edge of the beach between Los Santos and Flint County, just west of Flint Water. The Beat the Cock! triathlon is started beside the lighthouse on the beach. An oyster is also located south of the lighthouse underwater. The Los Santos Lighthouse has a similiar appearance to the Vice City Lighthouse in Ocean Beach. The Los Santos Lighthouse cannot be entered unlike the Vice City Lighthouse from the previous game.
If the player starts a gang war on the boardwalk of the lighthouse, the Ballas will not spawn or attack the player. However, on rare occasions, the attacking gang members may spawn underwater on the sea bed, making them nearly impossible to kill.
