Actually, you CAN get to Navel Rock, but unfortunately, there were some Nintendo Events, in which you go to a Toys R Us, and they download the tickets wirelessly onto your Fire Red/Leaf Green/Emerald game. That event has passed though, and I believe it was in 2006, and they are not doing the events anymore. But, there is another way: Using GameShark - a hack/cheat, which you type in codes, and you get to go to Navel Rock/Birth Island, OR even buy the Aurora Ticket to Navel Rock in a Poke'Mart. Unless you hate cheats, then there is no other way, except trading a friend from their game to yours.
Below: Guide for people who have gotten the ticket, but don't know how to catch Ho-Oh / Lugia/ Deoxys.
Navel Rock- Navel Rock has a level 70 Ho-Oh, and a level 70 Lugia. I believe that you can only catch ONE of them: Ho-Oh or Lugia, or I may be mistaken. If you want Ho-Oh, don't use "Confuse Ray" when its health is low, put it to sleep. It might hurt itself in Confusion when it is Confused. And don't use Poison either. Like all, legendaries, SAVE before you battle them, because, if you kill/make it faint, then you can't try again, unless you start the game all over again. Do the same for Lugia, and keep trying Poke'Balls. If you have your Master Ball still, use it, but if you don't, try using many Ultra Balls. Note: Beforehand, buy tons of Ultra Balls. If you are a starter, and use your Master Ball on Mewtwo, just remember, you CAN catch Mewtwo with an Ultra Ball, but save beforehand.
Birth Island - Birth Island has a level 30 Deoxys, but you have to do this pattern sort of thing with a moving triangle. To accomplish this, walk towards the closest side to you once your character in the game touches the triangle. My idea is, BEFORE doing the "triangle-pattern" thing, SAVE beforehand, because I think that if you don't accomplish it right, the triangle disappears and never comes back. Not sure though. Save AGAIN after figuring out the triangle-pattern thing, after a little character Deoxys appears on Fire Red/Leaf Green/Emerald.
Nintendo also said, that they MIGHT have a downloadable Mystic Ticket/Aurora Ticket in case you didn't get to the event, or wasn't BORN at that time, or didn't know about it at the time. But, no known download is known about yet, so if you are not patient, you can hack, with GameShark (which I don't recommend, because a lot of people say it screws up your game), or trade with a friend, who is fortunate enough and kind enough to trade you. In Poke'Marts, there is a clipboard on the counter. Click on it and it says up top, "Link Together With All." That is the thing you need, and then press "Ok". The person behind the counter will talk to you and say something like, " Oh! You know about the Mystery Gift?", and he tells you how to get it. But, to obtain the "Mystery Gift", you have to have a Wireless Adapter and connect it to your GameBoy. I think then, you go to the Main Menu of your Pokemon game, and click on "Mystery Gift". I am not sure you get the Aurora Ticket or the Mystic Ticket, because I haven't got a Wireless Adapter. BUT it's worth a shot! Good Luck! Hope this helped! ~ Anonymous =) =D
