When Minecraft came out over a decade ago, exploring underground was already spooky, but it was pretty monotonous; lava and the rare diamond block were the most exciting things to see. Nowadays, though, heading underground is a much more exciting experience. Caves are far more varied and interesting, and there are even deep-buried Ancient Cities to loot--if you can avoid the Warden.

There are dozens of biome types and subtypes aboveground, but below ground you'll find fewer biomes and more danger.

Note: This guide focuses on the Bedrock version of Minecraft, available on Windows 10, Xbox, PlayStation, Switch, and mobile.
