Best Minecraft 1.21 Coral Reef Seeds

Get ready for a life of tropical living.

Personal Reef

Seed: 5059114762744265000

In this virtual world, you’ll find yourself enveloped by vibrant corals. You’ll begin your dive just a short swim from a substantial Coral Reef, but there are two smaller reefs nearby that might catch your interest more. The first is situated near Spawn, while the second lies in a secluded area of the ocean adjacent to a Desert Village. These smaller reefs offer an ideal habitat for players seeking a coral reef experience without getting disoriented as easily as they might in larger coral formations.

Coral Beginnings

Seed: -3600559789931108364

A Coral Reef makes an excellent location for constructing a hideout. Being submerged underwater, it becomes challenging for most creatures, including players, to locate and assault you. The corals can serve as a camouflage for your base, concealing it from curious onlookers.

Both shallow and deep waters are teeming with vibrant coral formations, making this more than just a regular reef – it’s a two-tiered Coral Reef!
