To get to the first three islands you have to go to Cinnabar Island and beat the gym leader there. Then Bill will show up and ask you to go on a cruise and his friend will give you a pass to island 1, 2, and 3, using to port in Vermillion City. To get islands 4, 5, 6, 7, 8, and 9, you have to beat the Pokemon League. Once you do that, you have to have at least 60 Pokemon in your pokedex. That will give you the National Pokedex. Once you have that, go back to island 1, and you'll have to do a favor for Bill's friend. Once you complete what he asks you, you will obtain a pass that will allow you to go to islands 4, 5, 6, 7, 8, and 9, as well. !
