How do you get to Kanto in crystal?

Go to New Bark town then go east as far as possible and surf until you get to land. There is a cave in their. go into it and use waterfall. (HM you need after you beat blackthorn city's gym leader). Then travel through victory road and ??? will battle you. Then you must defeat the Elite Four (A.K.A. The Pokemon League) and then you will be able to continue on your journey.
