Minecraft – How to find Dungeons in Minecraft

An easy way, which you may consider cheating, is using a map viewer.

Without doing that, there are at least two ways:

• Find mossy cobblestone, which is guaranteed to be beside a dungeon (see the first paragraph of the Minecraft Wiki article on dungeons):

• Listen for a mass of zombie or spider sounds underground. They love to make noise and you can hear them through walls, making them easy to find. There's a chance that you'll find an underground cave or a dungeon near them. Creepers do not make noise but there are no such creeper dungeons.

Some guesses:

Levels have relatively little pattern between components like caves and veins so dungeons might be completely randomly placed, even near the top of the levels:

I'd guess that deeper down you have a better chance, but without diving into the code there's no way to confirm this.

Out of interest:

If your goal is to generate a map with lots of dungeons then Minecraft Seeds provides random seeds that do exactly that. Here are three examples:

• Two nearby dungeons after climbing a mountain.
• Three dungeons at spawn if you're too lazy to climb.
• Inside a dungeon if you're too lazy to walk.

Note that an update to map generation could change what a seed produces.
