End gateways are intradimensional portals generated in the End: some are spawned around the central island after each death of the ender dragon; others are randomly generated throughout the outer islands.

On the central island, up to 20 gateways can be spawned. These can send the player far away to the outer islands, each of which has a corresponding gateway that returns the player back to the central island. There are other randomly-generated gateways that always lead the player back to the End platform. They provide quick access to the different parts of the End dimension.

A group of 20 End gateways can be spawned around the edge of the central island, one at a time by defeating the dragon. Their configuration resembles a circle, equally distributed, surrounding the island at Y-level 75, at a distance of 96 blocks (regardless of angle) away from the center (0,0) in random order.

These gateways are referred in the game as END_GATEWAY_DELAYED. They function by sending the player far away to the outer islands, in the exact direction that that gateway is located relative to the island center (0,0).

They do not regenerate after the ender dragon has been defeated 20 times.

The position of these gateways are always fixed, as is shown below:

The formulas for these coordinates are (where the symbols mean "round down" and ):

The order in which these gateways are created as dragons are killed depends on the world seed.

Each of the 20 gateways on the central island, when it is first activated, spawns an additional gateway linked to it. These linked gateways are located much farther away, reaching out in all directions to the outer islands in the End dimension. They still arrange in a circular way, but their distances to the central island vary depending on the distance to the first land in their direction.

Their function is to send the player back to the original End gateway on the central island.

Details

The game first draws a line with a length of 1024 blocks from the center (0,0) through the northwest corner of the activated gateway. If the chunk at the end of the line contains any blocks above Y=15, the line is progressively shortened by 16 blocks until a chunk is found with no such blocks or the line reaches a length of 768. Then, if the chunk at the end of the line has no blocks above Y=15, the line is progressively lengthened by 16 blocks until a chunk is found with any such block or the line reaches a length of 1280.

Once a chunk is selected, it is scanned for any End stone blocks at or above Y=30 that have two non-full blocks^{[note 1]} above. If such a block exists the south-east corner of the chunk is selected,^[1] or if no such block exists in the chunk then a small island is generated at the end of the line at Y=75 and that position is selected. The position is then moved to the highest full block within ±16 on the X and Z axes (favoring the north and west in case of ties) and a gateway structure is generated 10 blocks above that position.

Knowing this, the position of the outer gateway can be manipulated. However, once an End gateway on the central island has been activated, it is indefinitely linked to the position of the generated gateway on the outer islands. Changing the position of the outer gateway is then no longer possible.

End gateways also generate naturally throughout the outer End islands (in the End Highlands in Java Edition). They are referred to in the game as end_gateway_return. Unlike the aforementioned gateways, these gateways teleport entities back to the End platform, allowing players to escape from the End without having to find their way back to the gateways generated when using one on the main island, which could be very far away. This makes it feasible to go deep into the End to search for end cities.

Entities that teleport through End gateways in this fashion do not cause the End platform to regenerate.

The End gateway is composed of an End gateway block confined within a vaguely octahedral formation made up of 12 bedrock blocks.

A magenta
  beam shoots out vertically from the top and bottom of the gateway when it is generated. The beam disappears after 10 seconds. When an entity enters the gateway, the gateway emits a purple
  beam instead for 2 seconds. In addition, this purple beam also emits automatically every 2 minutes (2400 game ticks).^[2]

The bedrock arrangement prevents the player from entering the gateway directly. Throwing an ender pearl or flying with elytra straight into the End gateway block teleports the player to the outer End islands. Players can also access the inside of an End gateway by constructing a water channel leading into it and sprint-swimming through the channel and into the gateway, or by crawling.

Once the gateway is activated, another End gateway generates in the outer End islands near to where the player is teleported; this gateway teleports the player back to the original gateway, providing a way to return to the main island.

In Java Edition, the position where the player or entity lands after teleporting is determined by a systematic algorithm: The gateway searches for a full block that isn't bedrock, starting from the northwest corner at the topmost height (Y=255) within a 5-block radius around the gateway block (shown as the block of gold in the image on the right). If there is a block at that position, then the entity is teleported onto that block. If there is no block, then the next position along the Z-axis is searched (shown as the block of lapis lazuli in the image on the right). This continues along each column in an 11×11 area at the same Y-level with the exception of blocks above, below, or directly adjacent (including diagonals) to the gateway block. If there are no blocks, it moves one Y-level down and repeats the sequence from the northwest corner again. It continues doing this until every height is checked. If there are no blocks within any of these points, it always teleports the entity exactly two blocks above the gateway block.

In Bedrock Edition, End gateways teleport the player using a different algorithm, but the exact details are not known.​^{[more information needed]} A few notable differences are:

• Entities can land on slabs and other partial blocks. Conversely, there seem to be certain situations when a teleport location is not considered valid.
• Entities can land considerably farther away from the gateway than an 11×11 area.
• If there are no valid locations, the game generates a small floating island near the gateway, and the entity lands on this island.

End gateways allow entities with passengers (e.g., a player in a boat, a shulker in a minecart) to go through them.

Issues relating to "End Gateway" are maintained on the bug tracker. Issues should be reported and viewed there.

• If an End gateway is broken (e.g. in Creative), players can still enter the gateway on the other end. This teleports the player to the broken portal, which does not regenerate.
• Using the [NBT Compound / JSON Object] exit_portal tag and commands such as /setblock, it is possible to create a gateway portal in the Overworld or any other dimension and program it to go to a location.
