lazing Hell (, Shōnetsu Jigoku?) is the fourth level of Impel Down in which prisoners are kept. At this level, a pool lies filled with boiling blood heated by a raging fire making it extremely hot. The heat caused by this is so intense that it also heats up the level directly above it. If one tries to jump down to this level from Level 3 using the large hole used for ventilation above but don't land on a safe place, then they're dead.

Freezing Hell (, Gokkan Jigoku?) is the fifth level of Impel Down in which prisoners are kept in. This is the level where criminals with bounties of Image:Bsymbol.gif100,000,000 and over are kept. In stark contrast to the level above it, the entire level here is a giant freezer. The level is so cold that not only do the prisoners kept here either freeze to death or lose pieces of their flesh from severe frostbite, but the food given to them is frozen to the level of being virtually inedible. Due to the extreme cold, Den Den Mushi don't function in this Level, thus cutting off both contact and surveillance, except on the locations localized around the entrances that connects Level 5 to the previous and next levels. Along with the severe cold, the level is inhabited by wolves. These wolves roam around the level like the beasts of Level 2, where they were originally stationed at. However, they proved to be too brutal to be in Level 2 as they also hunted the other beasts as well, including the Basilisk and the Sphinx.

Known as the The "Prisoners' Secret Flower Garden", New Kama Land (, Banchi Nyūkamā Rando?) is a hidden sub level of Freezing Hell, and is where all the prisoners who have been supposedly "demoned away" have gone to. The secret area is located inside rock between Levels 5 and 6. It was carved out long ago by a prisoner with a tunneling Devil Fruit power, and is a secret location unknown by the jailers. It is ruled by the "Queen" Emporio Ivankov, and it's called the Okama Paradise where all the Okama and prisoners party and have fun at all times. Indeed, it has been described by Iva as a "paradise within hell", and true enough, not one inmate from this hidden level is inclined at all to escaping the Great Jail as a result.

Eternal Hell (, Mugen Jigoku?) is the lowest level of Impel Down. It is where prisoners who are insanely powerful, have caused crimes extremely atrocious, or whose mere existences have become a major threat to the World Government itself are kept. The prisoners on this level have been given either the death penalty or a life sentence. They are basically "erased" from history.
