Minecraft wiki entry for Achievement_guide, associated text: First, you need an ender pearl, then throw it. Make sure there are no obstacles in front, so you won't teleport there. You can also go to the top of mountains biome and throw an ender pearl to other biomes, make sure to face straight and little a bit looking up, not looking down. You can also get this achievement when you teleport from top of obsidian pillar to end fountain. Or once you beat the ender dragon, enter the end city portion of the end, through the portal made of bedrock, with an ender pearl.
