A view of the Nether.

The Nether is a hell-like dimension, filled with fire, lakes and rivers of lava, and dangerous and powerful mobs.


Αρχείο:Full and Budget Nether Nether Portal (EW) JE1.png

Budget version (left), Full portal (right)

To access the Nether, the Player must construct a Nether portal in the Overworld (Nether portals created in the End will not activate). To create the portal, one must first construct an obsidian frame, ranging in size from 4x5 at minimum to 23x23 at maximum. Once the frame is constructed, it can then be activated by placing fire within the frame. When the portal has been activated, it will emit a purple mist.

An activated portal will allow most entities (exceptions include the wither, the ender dragon, and entities riding or being ridden by another entity) to be transported to a corresponding portal in the Nether. A new portal will be created in the Nether if necessary. The portal can be destroyed by breaking the obsidian frame, by a nearby explosion, or by placing water or lava into it with a bucket or dispenser.


Nether terrain is largely composed of netherrack that forms complex platforms and niches, with lava oceans, "lavafalls", and rivers of lava being frequent. Lava sources hidden in the netherrack are also common, making large mining projects dangerous. Random fires across the netherrack are yet another hazard to the unwary player. The Nether is horizontally infinite.

Bedrock comprises the top (below y=127) and bottom 4 layers in a rough pattern (in the console edition, it can also be found at the sides of the Nether, as world sizes are limited). Glowstone clusters hang from ceilings, and mushrooms grow abundantly on the ground. There are patches of floating gravel and soul sand. Small caverns form in the netherrack, which contain random nether quartz deposits. Near the level of the lava oceans, patches of magma blocks generate within the netherrack, making travel difficult and damaging to armor if not avoided.

Nether fortresses, the Nether's only naturally occurring structures, provide valuable loot, and are the only places where blazes and wither skeletons will naturally spawn. Nether fortresses are also the only place where nether wart naturally generates (in the console edition, nether wart will naturally generate anywhere on soul sand).

The Nether has no day-night cycle and no weather. The only natural sources of light are fire, lava, portals, and glowstone. A dim ambient light can be seen throughout the Nether, and is what light level 0 looks like. Light otherwise functions exactly the same as it does in the Overworld and the End.

If the player dies in the Nether, they will respawn in the Overworld; any surviving inventory items will remain in the Nether.

Locations in the Nether correlate to Overworld coordinates, but horizontal Overworld distances are scaled down by a ratio of 8:1 for travel in the Nether. Therefore, traveling one block in the Nether means traveling eight blocks in the Overworld.

Most items and blocks in the Nether function the same as they do in the Overworld, with a few notable exceptions:

  • Beds will explode and cause fires when a player attempts to sleep in one.
    • The explosion is larger than that of TNT.
  • There is no way to place liquid water in the Nether in a Survival game without cheats, besides the usage of a cauldron.
    • Using water buckets will produce steam and an empty bucket.
    • Ice that is melted or smashed in the Nether will also not produce water.
  • Lava flows twice as far (8 blocks) and much faster in the Nether than in the Overworld.
  • Grass blocks and leaves take a dead-looking brownish color, since the Nether is considered a warm biome.
  • Maps will only generate a brown-gray static pattern.
    • The player's direction indicator will spin randomly, although its location is still relative to the players location in the Nether.
  • Compasses are unable to find the original spawn point, as it cannot be set to a single point within the Nether.
  • Clocks are unable to determine the position of the Sun and Moon.
  • Building snow golems is essentially useless, as they will rapidly take fire damage and die, due to the Nether being a warm biome.


The Nether is home to its own share of mobs, most of which are completely fire-proof and immune to lava. Skeletons, chickens, and endermen are the only Overworld mobs that can naturally spawn in the Nether; wither skeletons have a small chance of spawning as a regular skeleton instead, and baby zombie pigmen can spawn as chicken jockeys. Other Overworld mobs like cows and creepers do not naturally spawn in the Nether, but they can wander or be shoved through a portal.

Naturally created[]

Naturally created blocks are created through a combination of events that lead these blocks to be placed by natural causes, not by the player.

Technical information[]

The Nether is saved in the same way normal worlds are, in the following locations by default:




~/Library/Application Support/minecraft/saves/worldname/DIM-1

Note: This Library folder is not the one in Macintosh HD, but the one inside your home folder. The only way to access this is to go to the Go menu, and select Go To..., and type ~/Library, or to go to the Go menu, hold the Option key, and select the "Library" option.



On all systems, be sure to replace "worldname" with the name of your world.

Note that DIM-1 does not contain its own level.dat; the level.dat in the parent folder is used for all dimensions. This means that even if a player changes the level data in the /world folder for a particular save, Nether portals will still take the player to the Nether world originally generated for that save and vice versa.

Deleting the DIM-1 file will reset the Nether, so that all player-made changes and buildings in that dimension will be undone.

0.31January 6, 2010
Map preview Hell.jpg
Added a map theme named "Hell". It was a normal map, but with a lava ocean, perpetually dim lighting, and a black sky with dull red clouds. Map themes were later removed in Infdev.
1.1.1September 18, 2010Notch mentions the return of the hell biome, and that it will be used for fast travel, based on a transportation method used in the novel series The Wheel of Time by Robert Jordan. Within a dangerous transportation system, "the Ways", people could travel a massive amount of distance in a few days instead of weeks.
1.2.0October 4, 2010This announcement poster hinted that the hell world would utilize portals and that distance traveled inside the hell world would be multiplied greatly on the map above ground.
October 8, 2010Notch reveals a new block type, now known as soul sand, that would be included in the new dimension.
October 10, 2010A screenshot was released by Notch depicting what the Nether would look like.
October 11, 2010Notch makes mention of the first mob to be added to the Nether, saying "You will hate the Ghast."
October 25, 2010Notch tweets that he is working on the second new Nether mob, and says that they are less dangerous but are otherwise "pointless."
October 29, 2010Notch was conflicted on naming the new dimension; he wanted to avoid "re-using existing religious names", and wanted to use a more creative and original name. He considered both "the Slip" and "the Nexus" but felt that neither felt "minecrafty enough." It was eventually changed to “the Nether” on the day of the Halloween Update release.
A preview of the Halloween Update was sent out to two gaming websites later that day.[1] Interestingly, the name "the Slip" was used in this release.
Halloween UpdateAdded the Nether, including ghasts, zombie pigmen, netherrack, soul sand, glowstone, and nether portals.
1.2.2Lava was made to flow farther than it did on the Overworld.
1.6May 02, 2011Portals were made to function properly in multiplayer, allowing players in servers to teleport between the Overworld and the Nether.
Beds in the Nether were made to explode if used.
Official release
1.0.0September 16, 2011Jens Bergensten tweets a teaser screenshot of changes to the Nether terrain generation, including nether fortresses.
September 19, 2011Jens releases a second teaser screenshot, showcasing the structure of the upcoming nether fortresses.
September 21, 2011Jens mentions that he is finished with most of the new Nether features, including two new mobs, one of which is a "retexturing attempt".
Beta 1.9-pre1Many new additions to the nether, including: magma cubes, blazes (as well as blaze spawners and blaze rods), nether fortresses (including nether brick, nether brick stairs and Nether brick fences), nether wart, ghast tears dropped by ghasts and gold nuggets dropped by zombie pigmen.
Beta 1.9-pre4With the addition of the Silk Touch enchantment, it was possible to legitimately obtain water using ice in the Nether.
Beta 1.9-pre5The ability to pick up ice blocks with the Silk Touch enchantment was removed.
1.2.112w06aSnow golems now take damage in the Nether.
1.3.112w16aAdded the /give command. Using it to get water or flowing_water blocks allows another way to place water in the nether.
12w17aIce can now be obtained with Silk Touch again, but ice no longer melts into water in the Nether.
12w22aRarely, Nether portals will spawn zombie pigmen.
12w27aGrowing nether wart is no longer restricted to the Nether – it can be grown in the Overworld and The End.
12w30aMade the Nether less laggy.
1.4.212w32aZombie pigmen can wear armor, and the sword they are holding makes them deal more damage.
12w34aAny mobs and entities can travel through Nether portals.
12w36aAdded wither skeletons.
1.4.612w49aAdded nether brick slabs.
1.513w01aNether quartz ore is added to the Nether, which spawns around netherrack.

Issues relating to “The Nether” are maintained on the issue tracker. Report issues there.


  • Notch once said that Jake, his co-worker, was a big key to the Nether.[citation needed]
  • Upon entering the Nether in singleplayer, the Overworld will essentially freeze, and resume when the player returns. This is due to chunks loading and unloading.
  • Pressing F3 in the Nether will display the biome as "Hell".
  • In the Console Edition, everything in the Nether is renewable due to the fact the Nether can be restarted any number of times from the main menu using the "Reset Nether" button. This can be done on PC only through save editing, by deleting your save's DIM-1 file, which resets the nether.
  • The numbers for the 3 dimensions are: -1=The Nether, 0=The Overworld, 1=The End. This implies that the Nether is the next dimension over from the Overworld in the "down" direction and The End is the next dimension over in the "up" direction.
  • The Nether — an endless cave filled with masses of air — appears to be an inversion of the End, an endless sky with a central mass of end stone.
  • In the Console Edition, the nether music in the festive mash-up pack is actually different from the original nether music, with some minor differences.
