I am in Melmond And i don't get it in this walkthrough that i am reading it says

For now, it would probably be best to go back to the peninsula tip near provoka. However, there is an area in the next section that I will explain where you fight giants with every step you take. Just level up until you have enough gil to buy the stuff in melmond, or more if you need to. If you get sick of the peninsula tip, try the area full of giants that I will explain in the next section.
I went where the Giants were and all this one said was "You can not pass" what am i supposed to do now? please help me!
