This big cave is a base under the island known as Black Sands. It is a hideout to Sosa's Army. It is also possible that this is the place where they stuck all the drugs into.
Description[]
This cave can be found on the South-East at the end of Black Sands. It is occupied by Sosa's boys. A small house, some boxes and even an Armored Boat can be found hidden in there. It has many explosive barrels and it will always get re-occupied by Sosa's men everytime you arrive there. Looking at the cave from far away the player can see there is a scary-looking face drawed on the tree with lamps.
