Best Minecraft Seeds [1.21]
The 10 best Minecraft seeds for 1.21 including survival, speedrun, building, and rare biome seeds. Coordinates for key structures included. Java and Bedrock editions.
Finding the right seed can make or break your Minecraft experience. Whether you want a perfect survival spawn, a speedrun-ready world, or a landscape that inspires massive builds, the seed you choose determines everything. We tested dozens of seeds on Minecraft 1.21 (the Tricky Trials update) and narrowed it down to the 10 best across multiple categories.
All coordinates in this guide are in the standard X, Z format. If you need a refresher on how the coordinate system works, check out our Minecraft coordinates explained guide.
How to Use Seeds
To use any seed from this list:
- Open Minecraft and click Create New World
- Click More World Options (Java) or scroll to Seed (Bedrock)
- Enter the seed number exactly as shown
- Create the world
Seeds work differently between Java and Bedrock editions. A Java seed will not generate the same world on Bedrock, and vice versa. Each seed below is labeled with which edition it works on.
Best Survival Seeds
1. Village Island Start with Trial Chamber
Seed: 8528274918837498573 Edition: Java Category: Survival
You spawn on a medium-sized island with a plains village right at spawn. The village has a blacksmith with iron gear in the chest. A trial chamber generates underneath the village at approximately Y=0, giving you immediate access to 1.21’s headline feature.
Key locations:
| Structure | Coordinates |
|---|---|
| Spawn village | 0, 0 |
| Trial chamber entrance | 32, -15 |
| Ocean monument | -280, 360 |
| Shipwreck | 120, -200 |
| Ruined portal | -64, 48 |
This seed is ideal for players who want a contained early game. The island limits your initial resources, creating a natural progression curve, while the trial chamber provides endgame loot within walking distance of spawn.
2. Double Village Spawn with Exposed Diamonds
Seed: -7135354340624206925 Edition: Java Category: Survival
Two villages within 200 blocks of spawn, one plains and one desert. A ravine cuts through the terrain between them, exposing diamond ore at the bottom. The desert village sits next to a desert temple with quality loot.
Key locations:
| Structure | Coordinates |
|---|---|
| Plains village | -80, 32 |
| Desert village | 96, 160 |
| Desert temple | 128, 176 |
| Ravine with diamonds | 16, 96 |
| Stronghold | 1200, -880 |
3. Mushroom Island Survival
Seed: 7749012223048183947 Edition: Java Category: Survival
Spawn on a mainland coast with a large mushroom island roughly 400 blocks to the east. Mushroom islands are the safest biome in the game because hostile mobs cannot spawn there, even at night or in caves. Building your base on the mushroom island gives you a mob-free zone while the mainland provides normal resources.
Key locations:
| Structure | Coordinates |
|---|---|
| Spawn | 0, 0 |
| Mushroom island | 400, -80 |
| Village | -240, 128 |
| Mineshaft under island | 480, -120 (Y=-20) |
| Ocean monument | 600, 200 |
Best Speedrun Seeds
4. Nether Fortress at Portal
Seed: 4776164391216949839 Edition: Java Category: Speedrun
This seed places a nether fortress within visual range of where your first nether portal spawns. A village near spawn provides beds for the dragon fight, and the stronghold is within 1,500 blocks. Competent runners can finish this seed in under 15 minutes.
Key locations:
| Structure | Coordinates |
|---|---|
| Spawn village (beds + food) | 64, -80 |
| Nether fortress | ~40, ~80 (Nether) |
| Stronghold | -1200, 640 |
| Second village | 320, -320 |
5. Zero-Zero Stronghold
Seed: -4534543029446564354 Edition: Java Category: Speedrun
The stronghold generates almost directly under world origin. Combined with a nearby village and quick nether fortress access, this is one of the fastest-pathing seeds available. The stronghold portal room is at approximately (12, 32, -48), practically underfoot from spawn.
Key locations:
| Structure | Coordinates |
|---|---|
| Stronghold portal room | 12, -48 |
| Village | -160, 96 |
| Nether fortress | ~-100, ~60 (Nether) |
| Ruined portal | 80, -32 |
Best Building Seeds
6. Mega Taiga Valley
Seed: 3218019498498494566 Edition: Java Category: Building
An enormous old growth taiga biome with a dramatic river valley cutting through the center. Towering spruce trees, podzol ground cover, and mossy cobblestone boulders create an atmosphere perfect for medieval or fantasy builds. The valley floor is wide enough for a full-scale town.
Key locations:
| Structure | Coordinates |
|---|---|
| Valley center | 240, -320 |
| Village (plain, on valley rim) | 480, -160 |
| Pillager outpost | -120, -400 |
| River junction | 160, -280 |
7. Cherry Grove Mountain Range
Seed: 116 Edition: Java Category: Building
A short numeric seed that generates a stunning cherry grove biome within 300 blocks of spawn. The cherry grove sits on a mountainside above a meadow, with pink petals cascading down the slopes. Mountain peaks above Y=200 provide dramatic backdrops for builds.
Key locations:
| Structure | Coordinates |
|---|---|
| Cherry grove | 240, 160 |

An exceptional world generation result where nearly every Overworld biome generates within a 2,000-block radius of spawn. This includes rare biomes like mushroom fields, bamboo jungle, eroded badlands, and ice spikes. Perfect for biome hunters and completionists.
Notable biome locations:
| Biome | Approximate Coordinates |

Seed: 195=4222nh8 Edition: Bedrock Category: Rare Biomes
A Bedrock-specific seed where you spawn at the exact border of a jungle, desert, and savanna biome.

How We Tested These Seeds
Every seed on this list was loaded in Minecraft Java Edition 1.21.4 or Bedrock Edition 1.21.50 (where specified), explored in both creative and survival modes, and verified for structure generation accuracy using the /locate command.
We prioritized seeds based on:
- Spawn quality. How useful is the immediate area around spawn?
- Structure density. How many valuable structures are within reasonable distance?
- Terrain variety. Does the world offer interesting landscapes?
- Practical value. Would we actually want to play a long-term survival world here?
- Uniqueness. Does this seed offer something you would rarely find randomly?
Tips for Finding Your Own Seeds
While this list covers excellent pre-found seeds, you might want to discover your own. Here are some approaches:
The Random Approach
Just create a new world with a random seed. If the spawn area is bad, create another. Most players find a seed they love within 5-10 attempts.
The Tool Approach
Use Chunkbase (chunkbase.com), a free web tool that lets you enter a seed and see the entire world map with all structures, biomes, and features marked. You can browse the map without loading the game.
The Coordinate Approach
If you know what you want (say, a village within 100 blocks of a mushroom island), use Chunkbase’s filters to search for seeds meeting specific criteria. Understanding how coordinates relate to structure generation helps you evaluate seeds quickly.
Version Compatibility Note
Minecraft seeds are version-dependent. A seed that produces a specific world in 1.21 may produce a completely different world in 1.20 or earlier versions due to changes in the world generation algorithm. Major generation changes occurred in:
- 1.18 — Complete terrain generation overhaul, new world height (-64 to 320)
- 1.19 — Deep dark biome and ancient city generation added
- 1.20 — Cherry grove, trail ruins, and suspicious gravel added
- 1.21 — Trial chambers and breeze mob generation added
All seeds in this guide are verified for 1.21.x. If you are playing on a different version, the structures and terrain described may not match.
Java vs. Bedrock Seed Differences
Java and Bedrock editions use different world generation code, which means the same seed number produces different worlds on each edition. This guide clearly labels each seed’s edition.
However, both editions share the same biome and structure placement logic for most features since 1.18. The differences are in fine details: exact tree placement, cave generation, and some structure interiors.
If you find a seed you love on Java and want the Bedrock equivalent, there is no automatic conversion. You will need to find a different seed number that produces a similar result on Bedrock.
Summary
The right seed gives you a head start on whatever Minecraft experience you are looking for. Speedrunners want fortress access and nearby strongholds. Builders want dramatic terrain. Survival players want villages, resources, and structure density. Whatever your goal, starting with a proven seed saves hours of wandering through mediocre worlds.
