You can teleport almost anywhere in Minecraft using the "/tp" command, but you'll need to enable cheats in your world first.
You can get a command block in your Minecraft Java or Bedrock world using cheats and a special chat command.
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.
