About these 1.20 seeds

Estimated spawn on land, with an ocean biome within 150 blocks is required for every seed in this category. Lists are computed separately for the version printed on each card.

1.20 (Trails & Tales) added cherry groves and buried trail ruins to world generation, and 1.20.1 is one of the most-pinned modpack versions — plenty of worlds are still being started on it. Every seed below was verified on 1.20's own generation, not back-ported from a newer list: 1.21 changed worldgen (trial chambers, then the pale garden), so a list verified there can't honestly claim these coordinates.

Verified for Java Edition 1.20 (Trails & Tales). Biomes, terrain and structures are identical across 1.20 – 1.20.6, so any 1.20.x world matches these maps — the only generation change in the patches (1.20.2 made diamond ore more common in the deepslate layers) doesn't affect anything these cards measure.

For the current Java 26.3 release, see the main ocean seeds — or the same list for 26.3 · 1.21.4 · 1.19 · 1.18 · 1.16. All 1.20 lists live under best 1.20 seeds.

Frequently asked questions

How is this different from the main ocean seeds page?
These seeds are computed for Java 1.20. The main ocean seeds list targets Java 26.3. Match the version on the card; older versions can generate different biomes and structure positions.
Which releases do these seeds work on?
The whole 1.20 line — 1.20 through 1.20.6, including 1.20.1 modpacks: biomes, terrain and structure positions are identical across the patches. (The one generation change, 1.20.2 making diamond ore more common in the deepslate layers, doesn't move anything on these cards.) On 1.21+ the same seed generates almost the same world, but trial chambers (1.21) and pale gardens (1.21.4) appear and a few placements shift, so use our main lists for current versions.
Do these seeds work on Bedrock Edition?
No — Java and Bedrock generate different worlds from the same seed. These lists are Java Edition only.
