You can turn on cheats in Minecraft by enabling it when you create your world, or by going into your Settings.

Enabling cheats in this version of Minecraft can be done at any time, and it is actually quite simple whether you are starting a new world or loading a game for a world that is already in progress.

You can teleport almost anywhere in Minecraft using the "/tp" command, but you'll need to enable cheats in your world first.
