Tutorial:Far Lands

The Far Lands is a dangerous place, both for players (due to lag, lots of darkness, hostile mobs, and falls) and the device Minecraft runs on. But, if you want to go to this place, here is how to reach it and lessen the lag. It was a terrain generation bug in Java Edition and Bedrock Edition that occurred 12,550,821 to 12,550,824 blocks from the player's spawn. It essentially formed the "edge" of an "infinite" world.

In Java Edition, the Far Lands can only be found in versions from Infdev 2010/03/27 (though they existed in previous versions, the world became non-solid half-way to the far lands, which made it impossible to reach without modding) to Beta 1.7.3. They start generating near the coordinates of ±12,550,821 on X and Z axes. Given that one block’s side is one meter long, the distance to the Far Lands from the world’s center of coordinates can be measured as about 12,551 km (7844 mi). There is no conventional way of using Creative or commands to quickly reach this huge distance, since they didn't exist in these old versions, except for multiplayer. Instead, the different methods listed below are used. If you do /tp <player name> 12550700 90 0, exit before you hit the ground, load the world in beta 1.7.3, you will be 124 blocks short of the far lands, this is a very easy way to reach it if you don't have the single player commands mod.

Just walking in the Overworld towards any direction (positive or negative X and/or Z axis) is the most time-consuming way; reaching the Far Lands from the world center would take 9 months of overall Minecraft gameplay. However, it is safer than walking in the Nether and doesn't require items difficult to obtain. Crafting a bed before starting the long journey is recommended; sleeping in it before the night falls completely will avoid the annoyance of hostile mobs in the way. Crafting a handful of boats will also help crossing large water bodies. Pay attention to heights and avoid falling from them. Since hunger was not present prior to Beta 1.8, you won't need much food but only enough to restore your health in case of you lose it by falling or being hit but if you are on creative the fastest way to reach it is by flying and sprinting toward the same direction.
