Technically Ash is not in Pokemon Crystal, instead there is trainer Red but we all know it is Ash. Trainer Red (Ash) is located in Mount silver. After you get every badge in the game, go to prof. Oak and he will unlock mount silver for you. you must use flash to see inside the cave and look around for Trainer Red.
Bulbasaur can only be obtained after you defeat Red on top of Mount Silver. Go talk to Oak when you defeat him you will be able to pick one the three original starters.

You must beat Red, the game's version of Ash, at the top of Mount Silver.
Red is at the top of Mount Silver, you need to use the HM Rock Climb to get all the way up to him.
The reason Red is on Mt. Silver is unknown. He had previously defeated everyone in the game. He probably is there because of the need to train.
