Cerulean Cave is inaccessible until you defeat the Elite 4 and defeated the team rocket ware house in the sevii islands. Once both the ruby and the sapphire have been returned to Celio, the cave will be made accessible to the player.

It should be in the Cerulean cave
Cerulean Cave can only be found in the first-gen games, such as Red, Blue, Yellow, Fire-Red and Leaf-Green. Hope this helps! :D
Cerulean Cave, Deepest point.
The Cerulean Cave is in Cerulean City. You have to surf from a place around Cerulean Cape down to the Cerulean Cave. The Cerulean Cape is north of Cerulean City across the bridge.Go to the north end of the nugget bridge then left down the grass and follow the mountain to it. Btw you'll need flash and you can find Mewtwo in it.
