Better than ever!

If you're looking to explore the oceans and live among the fish then we've got a bunch of great Minecraft Coral Reef Seeds for you to check out! These are for both Bedrock and Java, so you should be able to find something you like on any platform.

Bedrock Seeds

Coastal Coral Cove

Seed: 11000001

Looking for immediate access to a Coral Reef? This is the seed for you. You spawn in a swamp and need only to walk a few blocks to dive into a warm coastal region that is absolutely filled with a Coral Reef. The entire area also highlights the new cave generation system with dozens of massive, underwater caves for you to explore. This is the best Coral Reef seed for Bedrock that we've found so far!

  • Key Locations
    • Nether Portal: -567 72
    • Mineshaft: -456 120
    • Shipwreck #1: -152 40
    • Shipwreck #2: 24 24

The Caribbean Savannah

Seed: 220735489

The Coral Reef in this seed isn't massive, but the area around the Coral Reef is what made us want to add this to the list of best seeds. Players have access to a village near the reef, which can be seen from the tall, naturally generated mountain formation you see in the image. What better way to enjoy the view of your Coral Reef below?

  • Key Locations
    • Natural Formation: 601 251
    • Village #1: 760 152
    • Village #2: 264 -312
    • Village #3: 152 88

Coral Kingdom

Seed: 368592799

The hike to the location shown in the image for this seed is expansive, but well worth the travel time. This seed has the largest Coral Reef we've ever seen in Bedrock, and you can enjoy the view of it from one of the three Desert Villages that are in it. The Coral Reef spans across over 1000 blocks, so you will have plenty of underwater beauty to explore!

  • Key Locations
    • Coral Village #1: -3592 -1960
    • Coral Village #2: -3604 -2408
    • Coral Village #3: -4120 -2424
    • Ocean Monument: -4376 -1832
    • Desert Temple: -3384 -1336

Coral Oasis

Seed: 1730875277296305186

If deserts aren't your thing, perhaps you can get away from the heat and sand at this Coral Oasis just barely west of spawn in this interesting seed. At the oasis, you'll find a huge lake filled with coral and a bustling village a couple dozen blocks away. In such a barren area with so little life around it, it's wonderful to see an entire ecosystem thriving on its own. When you're up for an adventure, check out the Impossible Waterfall at the entrance of a huge open cave nearby!

  • Key Locations
    • Coral Oasis: -200 -30
    • Ruins Cluster: -384 -224
    • Impossible Waterfall: -480 -425
    • Nether Portal: -248 -344
    • Mineshaft: -280 -168

Coral Water Wonderland

Seed: 1730875277296305186

This seed contains the largest Coral Reef we have ever seen in the Java version of Minecraft. The image above doesn't quite do it justice, as it is just a small section of the reef. The warm ocean where the reef is located spans over thousands of blocks, and there are several sections of reef within. Truly: the amount of Coral Reef in just this section of the map is overkill! The only downside is that you have to make a sizeable walk to reach the reef.

  • Key Locations
    • Coral Reef: -1250 2275
    • Ruins Cluster: -856 1352
    • Nether Portal: -1128 1640
    • Shipwreck #1: -1256 1672
    • Shipwreck #2: -1351 1960

The Coral Badlands

Seed: -3707816544166824799

In this seed, you spawn in a seemingly normal Badlands biome. However, if you make a short walk, you'll find a massive Coral Reef connected to the Badlands that spans over hundreds of blocks. If you prefer warm climates and a life on the sea (with a ton of visible sea creatures and plants), this is the perfect map for you. Did you see the ghostly Shipwreck in the image?

  • Key Locations
    • Village: 8 -248
    • Nether Portal: 120 136
    • Ocean Ruins: 344 328
    • Shipwreck #1: 264 568
    • Shipwreck #2: 536 520
