Minecraft wiki entry for End_gateway, associated text: 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 suffocation prevention.‌[Java Edition only] Any entity that moves into the end gateway block also is teleported. Another way is to place a trapdoor on the gateway while standing on a solid block to force the player to crawl.‌[Java Edition only]
