The Island Closest to Hell (地獄に一番近い島, Jigoku ni Ichiban Chikai Shima?) is the western-most island on the southwestern side of the Galbadia Continent. It is much larger than the Island Closest to Heaven, and is easier to locate on a map, though it is only accessible by using the Ragnarok.
It is shaped somewhat like a misshapen "X" or an elongated "H". It, along with the Island Closest to Heaven, is known for having some of the strongest monsters, with all of them being level 100. This island's monsters are known to possess high Strength and Vitality stats. However, they are susceptible to status changes, unlike monsters in the Island Closest to Heaven.
Like its counterpart, this island is useful if one is looking for a lot of EXP and/or magic. As all the monsters on this island is susceptible to Quistis's Limit Break Degenerator, leaving Quistis in Critical HP and Junctioning Initiative will allow the party to clear out powerful enemies easily.
There are also 31 Draw Points containing various rare and powerful spells, and it is one of the few locations of the Ultima. However, not every Draw Point will be active at the same time, and oftentimes they take a long time to recharge.
