As the other have been recommending, the only "easy" way to get onto Balmung I'd with the character transfer service, which is a one time charge to bring characters from one server to another. (It's the USA, it's 18 USD, but I do not know the EU price).
Balmung used to open for a small period of time when most players were not logged in, but due tto he massive player overpopulation and gilfarmer bits that spam the login, even after a maintenance, the server typically closes after just a few minutes making it almost impossible to get in otherwise.
Although Square Enix says a server locked for character creation cannot be transferred to, many people have found this is not the case and have been transferring in for the past 2 years or so.
