The State of San Andreas is a fictional state in Grand Theft Auto: San Andreas. It is mostly based on California and Nevada (only having the city Las Venturas based on Las Vegas and some desert region) while there are other notable areas and landmarks nodding to areas of Arizona (mainly the desert and forest areas). San Andreas appears to be comprised entirely of islands as the state is surrounded by water, however, several maps throughout the state depict the northern regions (Tierra Robada and Bone County) connecting to the mainland (despite this, however, in the game it's possible to completely circumnavigate the state by boat). San Andreas' area is estimated to be 33 square kilometers in size (12.7 square miles), the largest setting in the GTA series up until GTA V's rendition of the same state.
The state is divided into three cities and five counties, the cities of Los Santos, San Fierro and Las Venturas, and the counties of Red County, Flint County, Whetstone, Tierra Robada and Bone County.
