After you beat the Elite Four and add 60+ Pokemon to the Dex, go to Prof. Oak and he will give you the National Dex, which also allows you to go to 4, 5, and 6 island. Just talk to the dude at Cinnabar Island. Hope I helped you out!
you have to beat the elite 4 before you can get the pass to the islands.
