Bayside Marina is both a functional public service facility and a district of the town of Bayside in Tierra Robada, San Andreas. This is the location of the Boat School, which the player may access in order to increase skill with piloting watercraft. The marina is located at the southeast end of Bayside, on San Fierro Bay. This location provides spectacular views of the city of San Fierro and of the famous Gant Bridge, which spans San Fierro Bay.
The mission The Truth is Out There was set here, but it was cut before the release of the game.
- This place will not trigger a 4-star wanted level if the player visits it before completing Yay Ka-Boom-Boom.
- In the original PS2 version, the area becomes under control of Los Santos Vagos, caused by type 1 of the Territory Glitch taking effect during Saint Mark's Bistro's required air trip from San Andreas to Liberty City, and can be taken over. The "gang war" only lasts for a single wave with 'weaker' weapons (Pistol and Baseball Bats).
