Bedrock Edition Far Lands

The Far Lands is the area that forms the "edge" of the "infinite" map. The distance from the center of the Minecraft map to the beginning of the Far Lands, 12,550,820 meters, is about 31% of the circumference of the Earth at its equator. When players make it to the Far Lands, they will experience an excessive amount of lag and the map will be severely distorted. According to Notch, this distortion can be fixed, but since no one is likely to make it to the Far Lands without some form of cheating, he says that he will likely not fix it since he likes the idea of a mysterious world beyond a certain distance.

Getting to the Far Lands
Getting to the Far Lands without the use of an external program would be a very difficult (or at least time consuming) task, taking about 820 hours to walk there from the center of the map. Instead, a level.dat editor can be used to teleport the player there. It is impossible for the player to spawn close to the Far Lands due to how extremely far away they are.

The boundary between the normal map and the Far Lands (defined by when the map starts generating the distorted terrain) occurs at X/Z of &plusmn;12,550,821.

The hard limit where chunks get overwritten is at X/Z of &plusmn;34,359,738,368, which is about 25% of the distance from the Earth to the Sun. At X/Z of &plusmn;2,147,483,648, (1/16th of the former distance), item positions, mob pathfinding and other things using 32-bit integers will overflow and act weird, usually resulting in Minecraft crashing.

At X/Z of &plusmn;1.798&#x2219;10308, the position of the player, represented by a double-precision floating point number, will overflow.

Using Single Player Commands, it is very easy to get to the Far Lands using teleportation. After pressing the chat key (default "T") to open up the console-like input window, using the "teleport" command (or its abbreviation, "t") followed by X, Y, and Z coordinates will allow the player to go wherever they want. For example:
 * To get to the Edge Far Lands' wall, try "t 12550820 140 0". Make sure either flying is turned on or damage is turned off, as otherwise you'll fall to your death.
 * To get to the Corner Far Lands (the walls' intersection), try "t 12550820 140 12550820". Again, make sure you're protected from fall damage.

Unfortunately there will be severe lag, and slower computers may crash upon this teleportation. Opening a GUI will make the Far Lands render much, much faster. You can do this by pausing (pressing Escape) or opening the Single Player Commands menu again.

Geography of the Far Lands
Both areas of the Far Lands feature extremely strange terrain, although they are significantly different. In both zones, any area beneath sea level, excluding regular caves, will be flooded with water. The Far Lands' structure is dependent on the seed used for generating the map, although the general patterns remain the same. Beyond X/Z of &plusmn;32,000,000, chunks are treated as permanently nonexistent, and will not generate. This value is hardcoded in the source code of Minecraft.

The Far Lands will generate biomes but most biomes will be indistinguishable except by the color of the grass. Desert biomes will be covered in sand and snow-covered biomes will be covered with snow, excluding the top of the map (because there's no space for the snow cover up there). Trees will generate somewhat normally, but can only be found in the upper areas of the map due to the need for grass.

Ores can be found up to their respective maximum heights just like in the normal world. Unfortunately, due to the flooding, everything except for coal is difficult, if not impossible, to acquire. In the solid areas of the Far Lands, normal caves will generate but will be limited and small. Along with the caves, dungeons (extremely rare) and lakes can be found in solid areas. Water and lava springs can be found out in the open and in caves.

Much of the open space in both areas is shrouded in darkness and thus hostile mobs run rampant, making the Far Lands as a whole incredibly dangerous. This is especially problematic in the Corner Far Lands due to its layered structure. The flooded zones are filled with squid.

Edge Far Lands (The Loop)
The boundary of the Far Lands Edge (that is, where it meets the regular map) looks like a solid wall, all the way to the top of the map (Y-coordinate 127) that is filled with gaping holes perpendicular to the edge. These holes are extremely long, perhaps infinite, and on the whole seem to change very little no matter how deep the player ventures. They can be blocked, either partially or completely, but such blockages are rare and temporary. This "wall of Swiss cheese" pattern continues beneath ground level, all the way to the bottom of the map, and seems to be partially caused by a large one-dimensional distortion in the map generator's output.

Corner Far Lands (The Stack)
At a corner, when two perpendicular Edge Far Lands sections meet, the Corner Far Lands begin to generate. Unlike the infinite-length holes in the Edge Far Lands, the Corner Far Lands contains more normal terrain. This terrain is "stacked" on top of itself to create a bizarre sandwich with layers of ground and air, which gives it its nickname. Each layer looks like a gigantic floating continent, hovering over the next layer, which is shadowed.

The number of layers isn't always the same, and varies between three to five. Layers can be grouped into three categories:
 * The top layer. This layer exists at the absolute top of the map. Occasionally there can be a lower area that isn't shadowed (this is technically a dry layer). The lower area is where a majority of the trees and passive mobs can be found, as the top layer receives almost all of the sunlight. Due to the lack of space the area at the absolute top can't have trees or mobs.
 * The dry layers. These generate slightly flatter than normal terrain and have grass, despite the darkness. At sea level massive floating beaches can be found, which will collapse if modified. Hostile mobs are very common here due to being in the shadow of the top layer. Rarely, there are holes in the top layer that allow sunlight to reach these layers. Caves that have one of these layers as their "surface" can occasionally be carved out of dirt instead of stone. These layers have cave-like ceilings made out of stone, gravel and dirt.
 * The flooded layers. Like the dry layers, these generate somewhat flat terrain, but it is comprised primarily of stone. Sand and sandstone will show up down here, even up to 30 meters below sea level. Except for coal, all the ores can only be found in these layers.

Sometimes there are extremely tall pillars of gravel that stretch from the ground to the ceiling of a layer. Likewise, some of the beaches that collapse will create pillars of sand all the way down to the ground, despite there not being that much sand to begin with. The Corner Far Lands is also prone to having near-perfect diagonal lines being carved into the ceilings or floors of layers. If traced, these lines all intersect at the corner (X/Z &plusmn;12,550,821). This seems similar to how the Edge Far Lands have a consistent pattern along lines perpendicular to their edge, but is much less pronounced.

In The Nether
The Nether Edge Far Lands look identical to the regular Edge Far Lands. They're constructed out of Netherrack with some Soul Sand mixed in. Glowstone will be found in coral-like structures like the rest of the Nether. Both the floor and ceiling bedrock layers will be present, as well as the lava ocean (at Y-coordinate 31). The Nether Corner Far Lands also look identical in nature to their real-world counterparts (although not necessarily exactly the same). They have a similar stack of layers and contain layers flooded with lava (at levels 31 and below) instead of water.

In the Nether, the terrible lag associated with the regular Far Lands will not occur.

Aether


In the Aether mod which adds a new realm to Minecraft similar to the Nether but with a heavenly theme, the Far Lands can still be reached. They are composed of various blocks found in the Aether realm, and unlike the rest of the Aether realm the Far Lands are not actually floating islands but are interconnected. Mobs still spawn in the Aether version of the Far Lands and the lag associated with the regular Far Lands occurs in the Aether version.

In the Aether version you can still teleport to where the Far Lands cut off, and the game does not immediately crash, the player will fall into the void of the Aether and teleport back to the normal Minecraft world, however when he appears in the normal Minecraft world he appears in the cut off of that world's Far Lands and then the game will proceed to crash.

In version 1.7.3 of the Minecraft Beta the player can teleport between the normal Minecraft world and the Aether even if they are in the Far Lands and this will not cause the game to crash, although it may cause more lag than if the Player had not teleported.

Effects of the Far Lands
There are many effects that will be noticed after traveling millions of blocks away from the center of the map. The very first effect that will be noticed is the jumpy or stuttering movement of the map, which isn't directly related to the Far Lands themselves but instead to floating-point precision errors. This jumpy movement is notable even at X/Z of 500,000. Players will experience extreme framerate drops and very high CPU usage, which will continue until Minecraft freezes completely. The framerate drops do not occur in multiplayer servers.

Some drivers (mostly laptops that can handle the lag) may distort the landscape visually, as seen in this picture.

As the player journeys even deeper into the Far Lands, the effects worsen to the point where the game is unplayable. At X/Z &plusmn;32,000,000, block physics stop functioning correctly. Lighting doesn't work and the blocks, although they appear to be there, aren't solid. If the player tries to walk on these blocks, he or she will fall into the Void. Because of this, it's impossible to get even close to X/Z &plusmn;34,359,738,368 or &plusmn;2,147,483,648 without the assistance of editors or mods. At excessive X/Z positions, World Renderer no longer works, or takes incredibly long times and uses most, if not all CPU usage. It then becomes almost impossible to close Minecraft without the Task manager.

Additionally, as seen in some of the screenshots, sand and gravel fall in an odd pattern. Only one in every four blocks responds to gravity. This may also be due to floating-point precision errors, as the falling sand and gravel are entities using floating-point numbers for positions.

Weather is not affected by the Far Lands directly but is by their terrain. Lightning bolts that hit surfaces at the top of the map (Y-coordinate 127) will be invisible and will not cause fire. The particles created when rain hits these surfaces will be black instead of blue. Snow will not accumulate on these surfaces either (because there's no space). As of Beta 1.6, these effects are unique to the Far Lands as it's impossible to artificially place solid blocks at layer 127.

In previous versions of Minecraft
Very little is known about the Far Lands of older versions of Minecraft for many reasons; they had no official name, and few knew of their existence. Fewer still tried to make them known to the world, and so they remained unknown. When Notch mentioned them on his blog and gave them an official nickname, interest took hold.

In Infdev, although the Far Lands existed, many of the side effects didn't. There was no lag or stuttering movement, and beyond X/Z &plusmn;32,000,000, the blocks would simply not render. Walking off the edge would cause the player to become stuck in a glitched position, unable to escape.

It has been confirmed that in Alpha v1.1.2, the blocks would not render beyond X/Z &plusmn;32,000,000, like older Infdev versions. It is unknown in which version the "phantom blocks" started to render.

Trivia

 * The Far Lands spawn hostile mobs at a rate far higher than any natural chunk, due to the sheer amount of space in absolute darkness. In the Corner Far Lands, the spawn rate likely approaches the maximum possible because the stacked terrain works like a mob tower.
 * The flat plane at the very top of the Corner Far Lands tends to light incorrectly in day-night transitions. This is because the sunlight calculation doesn't work when the entire chunk is blocked at Y-coordinate 127.
 * Even traveling through the Nether, it would take 102 hours of walking in a straight line to get to the Far Lands.
 * Entering a Portal which would take you to either world's Far Lands will cause Minecraft to crash.
 * The Edge Far Lands' average block composition: 36% Stone, 25% Air, 23% Water, 10% Dirt/Grass, 2% Bedrock, and 4% others. (Based off of a 14x14 chunk selection)
 * The Corner Far Lands' average block composition: 40% Stone, 16% Air, 28% Water, 10% Dirt/Grass, 2% Bedrock, and 4% others. (Based off of a 14x14 chunk selection)
 * The YouTuber Kurtjmac, (found here)is one of the few players that is attempting to reach The Far Lands without the use of third party modifications or the use of teleporting. He is also one of the few people currently documenting his entire trip to The Far Lands. As of June 5, 2011, he has set up the site farlandsorbust.com to give more background information on his journey. He also has a fundraiser for childsplay charity.
 * With Single Player Commands, you can turn off the excessive lag you may encounter in the Far Lands by turning off drops with the commands "drops", however you will still have the awkward movement.
 * Even though Beta 1.6 made it impossible to place solid blocks at layer 127, the Far Lands' flat "ceiling" still gets generated there.
