Trial Chambers are underground structures in Minecraft filled with combat challenges, Trial Spawners, and valuable loot. The easiest way to find one in Survival mode is to buy a Trial Explorer Map from a Journeyman-level Cartographer. If cheats are enabled, you can find the nearest chamber instantly with a command.
1. Get a Trial Explorer Map
A Trial Explorer Map points you toward a nearby Trial Chamber. Follow these steps to get one:
- Find a village and locate a Cartographer villager.
- Trade with the villager until it reaches Journeyman level.
- Check its available trades for a Trial Explorer Map.
- Buy the map and follow its marker toward the Trial Chamber.
The map trade is not guaranteed for every Cartographer. If your villager doesn’t offer one, try leveling up another Cartographer.
2. Find Trial Chambers Using Commands
If you have cheats enabled, use the /locate command to find the nearest Trial Chamber.
Java Edition:
/locate structure minecraft:trial_chambersBedrock Edition:
/locate structure trial_chambersThe command returns coordinates for the nearest structure. Travel to those coordinates and dig underground to find the entrance. You can also switch to Spectator mode to inspect the structure more easily.
Important: Trial Chambers only generate in chunks created with Minecraft 1.21 or later. If you’re exploring an older world, travel into newly generated chunks to find one.
3. Find Trial Chambers Without a Map or Commands
If you prefer exploring naturally, search underground caves and mining tunnels, particularly around the deepslate layer below Y=0.
Look for unusual structures made from copper and tuff blocks. These materials are distinctive and can help you recognize a Trial Chamber when part of it is exposed in a cave.
This method takes longer than using a map or command, but it works without trading or enabling cheats.
4. Prepare Before Entering a Trial Chamber
Trial Chambers contain hostile mobs, traps, and combat challenges. Bring these essentials before exploring:
- Armor and weapons: Equip your best available gear.
- Food: Carry enough to restore health throughout multiple fights.
- Torches or other markers: Mark explored rooms and routes to avoid getting lost.
- Blocks: Use them to create barriers, bridges, or safe positions.
- Water bucket: Useful for handling certain falls and navigating some hazards.
- Healing supplies: Bring suitable potions if available.
Set up a safe supply area near the entrance if you plan to explore the entire structure.
5. How to Complete Trial Chambers
Defeat Trial Spawners
Trial Spawners activate when players approach and spawn waves of hostile mobs. Defeat all the mobs from a spawner to complete its challenge and receive rewards, which can include a Trial Key.
Clear rooms carefully instead of activating several spawners at once. Use doorways and obstacles to avoid being surrounded.
Open Vaults with Keys
Trial Chambers contain Vault blocks that reward players with loot.
- Regular Vault: Requires a Trial Key.
- Ominous Vault: Requires an Ominous Trial Key.
A regular Trial Key will not open an Ominous Vault. To attempt the more difficult ominous challenges, you need the appropriate Ominous effect and key.
Search Every Room for Loot
After defeating the mobs, check nearby containers and hidden corners. Look inside dispensers, barrels, and decorated pots, and watch for traps when entering unfamiliar rooms.
You can also mark cleared rooms with blocks so you know which areas you’ve already explored.
6. Tips for Exploring Trial Chambers
- Explore room by room: Clear one area before moving to the next.
- Watch for Powder Snow: Some rooms contain hazards that can slow or trap you.
- Check the copper bulbs: Use an axe to remove oxidation from copper bulbs and restore their brightness.
- Save your keys: Use Trial Keys and Ominous Trial Keys on their matching Vaults.
- Don’t rush the fights: Prepare for each Trial Spawner before activating it.
Frequently Asked Questions

Buy a Trial Explorer Map from a Journeyman Cartographer. If cheats are enabled, use /locate structure minecraft:trial_chambers in Java Edition.
At what Y-level do Trial Chambers generate?
Trial Chambers commonly generate around the deepslate layer, often below Y=0. However, their exact depth varies, so there is no single Y-level that guarantees you will find one.

Yes. You can find them in newly generated chunks after updating to a version that supports Trial Chambers. Previously generated chunks do not automatically regenerate to add new structures.

What key opens a Vault?
A regular Vault requires a Trial Key. An Ominous Vault requires an Ominous Trial Key.
Final tip: Use a Trial Explorer Map for the easiest Survival experience, or the /locate command if you want to reach a Trial Chamber quickly. Bring good equipment, clear each room carefully, and collect your rewards before moving deeper into the structure.
