You'll only can to go this place after you get your own airship at Ghalzabine. Just when you have got it, you could land in the near waters of the right place to farm your experience.

On the other hand, you need some special rare equipable items (marked as "Other" in game):

• x1 Attract Charm
  
• x2-3 Critical Band

Moreover, for best and fast leveling up XP on your team, you may use Corone break skill called "Experience gift" which double the amount.

Here on this map is my Fray's avatar where you need to go for this:




























Which looks like this:

On this tiny island you will fight basically against two types of monsters that interest to us for leveling up fast and easy. They are called Metal Gelatin and Full Metal Gelatin.
They look like these:


























So we need to go against this grey-white creatures because they can easily give us a thousand mile experience points, and with a small trick we can double or more that.

But how to beat'em easily? If you try to hit them, with normal attacks, with break or energi ones you will pay closer attention to just see 1 damage deal, and even they have very low HP, we need to kill them fast without put our team in risk (as my Fray above, hehe), but more importantly because they are the only rare enemy on this game that always try to run away the battle. So we need not only to be fast for us, but because to kill them before they escape the fight.

The simple trick to do a full damage on this monsters are critical normal attacks. How we can do this? With the critical band I told you before. With this one you'll do a 100% critical normal attack, so the monster will be insta-killed.

Now, and optimal way to get a lot of experience -and without using the Heart experience item that you can buy with AGP or Battle Coins on the Arena-, is going with Aurra and Grande as assist team (this guy, Grande, is called "big" on spanish, teehehe) because they will put a yell of experience at x1.5. So this means for us to going with this team on fight: Enah, Corone, Walter and Fray. (Don't ask me why my Corone is so pinky kawaii, is a secret, shhhh).

Therefore, try to put Atract Charm on Corone (or Grande or Aurra) for getting the insta-fights on world map and do as many as you want more fast. Then pick the Critical Band for Fray and Walter (and maybe Enah if you want), you can change this at your convenience with the most fastest character in this team because you need to hit early them to kill before they run away (or kill your team, haha).
Best order to go in fight is: Corone the most fastest possible to cast break skill "Experience Gift" on team, this will do a x2 on XP amount plus yell x1.5 of Grande and Aurra. After this, just attack with your Fray and Walter (or Enah) with normal attack that will become critical thanks to the Critical Band.

For increasing more the total amount of XP you can go with another trick with Enah. As you may now at this point on game, when you get a better hit count number, you get better bonus experience, SP and gold. So, with the break skill's Enah called "Maximum is 13" and with the rare object "Hitman" you could do nearly 40 to 60 hits, and this means more XP for your characters of course.

Well, hope to have helped some people for leveling up fast and easy on this nice game, because despite the game has got very poor sales, deserves to be played for JRPG lovers on Steam. Don't let pass out this game if you have not played yet. Is above the average one on Steam and really enjoyable.
