Best Minecraft Trial Chamber Seeds for Java 1.21+
16 seeds with a trial chamber, labelled for Java 1.21+ — copy one, or open it in the Seed Map to scout it first. 2 Bedrock seeds are listed separately: the map follows Java generation, so they get no map link.
Where a seed's write-up gives coordinates, we ran Minecraft's Java structure-placement algorithm for that seed and show how far the nearest placement candidate is from them. A candidate is where the game attempts a structure; it still needs a suitable biome to generate, so treat a match as a strong lead rather than a guarantee.
