If you have an Xbox Live Gold or a Minecraft Realms membership, you can go into realms online, which are created by Minecraft players. With the new title update, this Dubai Trophies Realm includes the Caves and Cliffs: Part 2 area. You can either go to the teleporters near the base game achievements area to teleport to the Caves and Cliffs Part 2 area, or just use the speed pads that make you go really fast to go all the way to the end.

There would be teleporters that will teleport you to a place where you can get that specific achievement in the achievement areas. The descriptions to earn the achievements in the realm are in English and Arabic.
