Minecraft 1.21: Top 20 Best Seeds for December 2025
20 – Deadly Lava Lush Cave

- Seed: 6277197848659693478
- Spawn: -8, -8
- Biomes: Lush Cave, Taiga
Lush Caves are filled with unique blocks and wildlife that every player should attempt to gather in their Minecraft worlds. Their glow berries serve as an easy food source, the moss blocks speed up the hatching of Sniffer eggs, and the unique plants make for great decor. This seed puts players in a Taiga that is home to a large Lush Cave and a Taiga Village. If exploring the cave gets boring, players can head south to take on a Trial Chamber using the loot they’ve gathered in the cavern.

19 – Sunflower Plains Village

- Seed: -5294650445158980743
- Spawn: 259, -460
- Biomes: Flower Forest, Plains, Sunflower Plains
A sprawling village surrounded by sunflowers is the first thing Bedrock players will see in this world. Take over one of the town’s homes for your first base while using the villagers to farm plenty of wheat. When you want to craft iron gear, explore the ravine next to the village or walk south to mine ores in a Stony Shores biome. Instead of the village, Java players will have easy access to a shipwreck and several clusters of Cold Ocean Ruins.

18 – Snowy Treasures

- Seed: 8458230823786708092
- Spawn: -269, 310
- Biomes: Frozen Ocean, Snowy Beach, Snowy Plains, Snowy Taiga
Snowy biomes can feel sparse in resources, especially since structures like Trail Ruins and Cold Ocean Ruins are often hidden beneath snow and ice. Luckily, the snowy and Frozen Ocean biomes in this seed are filled with plenty of treasure in guaranteed structures. All players will find a set of Trail Ruins and a shipwreck on the edge of a Frozen Ocean. Java players will also have access to a large Snowy Village, while Bedrock gamers will explore the Frozen Ocean for Cold Ocean Ruins.

- Biomes: Basalt Delta, Plains, Forest, River
Bedrock players looking to head straight into the Nether will enjoy this Minecraft world. The world’s spawn is made up of a combination of Plains and Forest biomes filled with rivers. There are three Plains Villages in this area, with the second having a Blacksmith with enough obsidian to repair a ruined Nether portal nearby. It will take you straight into a Basalt Delta biome near the bottom of the Nether.

- Seed: 7840694599492271063
- Spawn: -993, -857
- Biomes: Desert, Jungle, Mushroom Fields, Stony Shores, Warm Ocean
A cozy survival island inside a Warm Ocean is perfect for players who want to experience everything Minecraft’s seas have to offer. One half of the island is in a Kelp Forest, while a Coral Reef surrounds the other half. Since the surrounding ocean is mostly a Warm Ocean biome, players will have a chance to get Sniffer Eggs from nearby Ocean Ruins. Bedrock players will have a Jungle Temple on the island. In contrast, Java players will have a shipwreck off the island’s southern coast.

- Biomes: Bamboo Jungle, Forest, Jungle, Sparse Jungle
Jungle Temples and Trail Ruins structures are found scattered around this large Jungle biome. Most of the structures can be found in pairs, letting you gather more loot in a single trip. Bedrock players will find a unique Trail Ruins structure that has merged with the bottom of a Jungle Temple. The only clues to its existence are a few terracotta and gravel blocks poking through the temple’s cobblestone floor.

- Seed: 2916547943699047976
- Spawn: 40, 22
- Biomes: Dark Forest, Deep Dark, Pale Garden
Two Pale Garden biomes hover over the top of this Woodland Mansion. Their hills collide with the Mansion’s structure, causing dirt blocks and glow berries to appear in the Mansion’s many hallways. Exploring the Pale Garden to the right will lead you to a large Lush Cave. Follow the cave down to drop through a one-block-wide hole that will place you right next to a Deep Dark biome.

- Seed: 3838058575941151168
- Spawn: -328, -447
- Biomes: Beach, Dark Forest, Old Growth Birch Forest, Swamp
Nothing makes a survival island more interesting than a wide variety of biomes and a Trial Chamber. Both console and PC players will find this Trial Chamber, as well as a ruined Nether portal, a shipwreck, and a few Cold Ocean ruins around the island. If you’d rather explore Warm Ocean Ruins, there are a few hidden along the western edge of the same ocean.

- Seed: -3426591315744277465
- Spawn: -723, 102
- Biomes: Desert, Mangrove Swamp, Windswept Savanna
Three biomes collide to form one magnificent Desert in this Minecraft world. A winding Windswept Savanna biome sets the stage, with a large Mangrove Swamp using the Savanna’s hills to tower above the Desert’s sand. Bedrock players will have a village and a Desert Temple hidden behind these tall biomes. In contrast, Java players will need to dive deep into the sea to explore Warm Ocean Ruins and shipwrecks.

11 – Jagged Peaks Mountain

- Seed: 5428247502997800210
- Spawn: 0, 0
- Biomes: Cherry Grove, Grove, Jagged Peaks, Plains, Snowy Slopes
Mountains are one of the safest places for Minecraft players to live. Their high peaks encircle their inner craters like natural stony walls, keeping out both enemy players and hostile mobs. In Bedrock Edition, players will find a small Plains Village and a ruined Nether portal hidden behind this mountain. Java players will have two Plains Villages located along the northeastern and southwestern sides of the mountain instead.

10 – Coral Reef Ruins

- Seed: -8496968123411647993
- Spawn: 632, 439
- Biomes: Coral Reef, Desert, Warm Ocean
Coral Reefs only spawn in Warm Ocean biomes, making them a great biome to discover Warm Ocean Ruins in. This Coral Reef is home to several clusters of Warm Ocean Ruins as well as a handful of shipwrecks. With so many ruins available, you’re practically guaranteed to find a pair of Sniffer Eggs! Lucky players will find a few blocks of moss in one of the reef’s shipwrecks. Place them on the ground, then place the Sniffer Eggs on top of them to help them hatch faster.

9 – Triple Trail Ruin Taiga

- Seed: -8194770365534910030
- Spawn: -3, 9
- Biomes: Old Growth Spruce Taiga
This large Old Growth Taiga is home to three separate Trail Ruins structures. The combination of the three ruins should let you get all of the archaeological items that can only be found by brushing the suspicious gravel in Trail Ruins. Since they are in relatively close proximity, I recommend building your base in the center of the Taiga and branching out to excavate each one.

8 – Beneath the Desert’s Mangrove Swamp

- Seed: -7754244304421584389
- Spawn: 136, -62
- Biomes: Desert, Lush Cave, Mangrove Swamp
Mangrove Swamps and Deserts are one of the best biome combinations in Minecraft. The Desert provides access to a variety of structures with helpful treasures, typically Desert Temples and Desert Villages. Meanwhile, the Mangrove Swamp contains important natural resources that don’t typically exist in large Deserts. It’s a perfect set of biomes that gives you everything you need to survive well in Minecraft. As a bonus, the area beneath these two biomes is home to four Trial Chambers, so you’ll have easy access to all of the exclusive loot found within them.

7 – Ancient Badlands

- Seed: -2401735794934395880
- Spawn: 9, -40
- Biomes: Badlands, Deep Dark, Eroded Badlands, Wooded Badlands
If Ancient Cities are your preferred structure, this Badlands seed will be the Minecraft world of your dreams. There is not one, not two, but eleven Ancient Cities to find scattered within the giant Deep Dark biome beneath this arid biome. Several of these cities intersect with a Dripstone Cave biome, while the rest stick solely to the Deep Dark.

6 – Mushroom Island in Warm Ocean

- Seed: 1546777713678868492
- Spawn: -468, -650
- Biomes: Mushroom Fields, Plains, Warm Ocean
It’s not every day that you’ll spawn on a coastline just a short swim away from a Mushroom Island. The coast is home to a Bamboo Jungle, so I recommend bringing Jungle saplings and bamboo with you to create a consistent supply of wood. There are plenty of Small Warm Ocean Ruins and shipwrecks around the island that can be looted for resources. Just make sure to bring a brush with you for a chance at getting Sniffer Eggs.

- Seed: 7506639709679732064
- Spawn: -6, -2
- Biomes: Desert, Mangrove Swamp
A Desert Temple has mysteriously sunk into the sands of this vast Desert. If it weren’t for its unique staircase-like roof and a nearby puddle of water, you wouldn’t know it was beneath your feet. Luckily, the hole in its roof is intact, so you can still drop directly into it. You’ll find a ruined Nether portal and a Pillager Outpost to the east of this Temple. There is also a Desert Village a short walk to the southwest.

- Spawn: 23, -33
- Biomes: Deep Dark, Cherry Grove, Meadow, Plains
In addition to being beautiful, this Cherry Grove has numerous untapped resources that make it a great place for survival players to live. Firstly, it has a Plains Village and a ruined Nether portal next to it on the surface. The ruined portal’s chest has enough obsidian to repair its frame and a flint-and-steel to light it. Secondly, the area beneath the grove is home to both an Ancient City and a Trial Chamber. These structures will give you access to a lot of unique items like the Silence armor trim.

3 – Jungle Desert Border

- Seed: 5192719823140580015
- Spawn: 1, 3
- Biomes: Desert, Jungle, Warm Ocean
A lush Jungle collides with a lively Desert in this 1.21 seed. The Jungle is home to a few newer structures, including a set of Trail Ruins and a Trial Chamber. In contrast, the Desert has structures that have been around for a long time, like a village and a Desert Temple. Players wanting to do a bit more archaeology will find a variety of Warm Ocean Ruins scattered around.

- Seed: -6155022544245158214
- Spawn: -266, -294
- Biomes: Badlands, Desert, Warm Ocean
Desert Temples next to hills look more like staircases than the structures they actually are. In this world, Bedrock players will spawn near a Desert Village on top of a hill. Next to the village is a Desert Temple that has merged with the ridge beneath the town. The Temple forms a small staircase leading up to the eastern half of the village. If you aren’t careful, you’ll wind up falling through the top of the temple while walking through the town.

- Spawn: -54, 70
- Biomes: Dark Forest, Pale Garden, Plains
Woodland Mansions in Pale Garden biomes provide a unique challenge only found in Minecraft 1.21. With the recent addition of the Pale Garden’s Creaking mob, entering and exploring a mansion within this biome becomes a difficult task. You’ll need to navigate through the gloomy garden while avoiding or destroying any Creakings that spawn to make it to the mansion’s door. Once inside, you’ll then have to fight your way through hordes of enemies to claim the structure’s many treasures.
