Best Minecraft 1.21 Seeds for Java & Bedrock
By the ChunkScan Team · Updated October 2026
Minecraft 1.21, Tricky Trials, added trial chambers: underground vaults with trial spawners, the breeze and the mace. Later 1.21 drops added the pale garden and the creaking. The seeds below are Java worlds with a trial chamber within 200 blocks of spawn, closest first, so the new loot is a short dig away.

What changed for seeds in 1.21
1.21 added one structure, the trial chamber, which generates underground in most overworld biomes; about 60% of scanned seeds have one within range of spawn. The pale garden biome arrived in 1.21.4 and replaces some dark forest areas, so a seed's dark forest can be a pale garden from 1.21.4 on. Because of the new structure and biome, a 1.20 seed list is not a 1.21 list: check a seed in the version you play.
Are the seeds the same in Java and Bedrock 1.21?
No. Java and Bedrock share the biome layout for a seed, but structures are placed with different rules, so a village at spawn in Java can be hundreds of blocks away in Bedrock. ChunkScan scans both editions separately for 1.21: the list above is Java, and the Bedrock link above opens the Bedrock seed search.
Do 1.21 seeds work in 26.1?
Yes. 1.21 and 26.1 generate the same worlds, so every seed on this page gives the same biomes and structures in both. ChunkScan shares one scan between them.
