Go to any island at any time in the game
You need to activate the jetpack cheat (up, down, left, right, L1, L2, R1, R2, up, down, left, right) and you probably want to activate the never wanted cheat (circle, right, circle, right, left, square, x, down) or else you will have a four star wanted level after you "trespass" meaning you go past the bridge walls on the road. The get rid of wanted level cheat will not work because you will still be commiting a "crime" after you enter it. So have fun going where ever you want to go. Oh, you should go to the "island" to the left of were you start the game, not the actual island to the north. And go to the airport and find a helicopter, and fly away! It's fun.
