Q&A for How to Build a Sky Island in Minecraft

Method One: Use your existing way to get up to the island, but secure the perimeter with a fence and an iron door so no mobs can get in. However, creepers can blow things up or a fellow player can troll you, so you should experiment. Method Two: Enable cheats by exporting your world to LAN and enable cheats. Go into the island, press F3 and write down the coordinates. Press F3 again to get rid of the weird text. Get down to the ground. Use /tp X Y Z where X Y Z are the coordinates. Method Three: Enter the command/difficulty p.

You can make it very high up in the sky with a solid surface as the ground. If you fall, you will die from fall damage.

if you are in creative mode you can use the water bucket to make a lot of water.

Yes.

Yes. On Minecraft, you can do all sorts of things! Follow the steps above, but with water instead of sky.

Yes. You need a big enough island though, and if you want it to spawn an iron golem, you'll need at least 10 villagers and 20 beds in 1.16.

Of course! You can do this in survival too. However, mobs or players may climb up if you don't secure it.

Try to make a defence as soon as possible. try to go back to the surface and get some materials (like redstone, pistons, anything). If the other player attacks your island, try to get the best sword/axe to attack the other player (like PvP). If the other player stoles your diamonds, then make a better protection to your chest full of diamonds (maybe like hidden door to the diamond vault).

You can do that on any version of Minecraft, just use your console's version of the controls for moving and flying, and placing and breaking.
