Double Ancient City Cave
Directly below a mountain spawn, you'll find a massive dripstone cave that connects two different ancient cities together.
Spruce Mountain Bowl Lake
You find yourself spawning next to a cave, inside a large mountain bowl with a perfectly centered lake at the bottom. Perfect for building your dream home.
Four Ancient Cities Fully Connected (quad Ancient City Complex)
I found a seed where four separate Ancient Cities generate as one continuous structure. No walls or cave gaps between them - fully merged into a single Deep Dark complex!
Skull-shaped Cave Entrance
A rare cave entrance that looks like a skull, complete with eye sockets and a central drop, naturally generated at the surface.
Exposed Lush Cave at Spawn
You start in what looks like a typical wooded badlands - but turn around and look behind you at spawn and right there is a mountain-filling lush cave, no pickaxe required. Keep exploring, and the lush cave network goes on, and on, and on...Great for a fairy cottage of moss and stripped oak logs, a Pueblo style house made out of stacked terracotta rooms, or an axolotl breeding operation. Just be careful on the way down.
Cherry Grove Ring Mountains with Cliffside Village & Exposed Mineshaft
A rare mountain formation creating a thin ring around a large body of water, with multiple peaks partially covered in Cherry Grove. A village has spawned high up on the mountainside, stretching down the slope - something you don’t see often with villages at this height.Near the village, the mountain is naturally hollowed out with large open holes, revealing an exposed mineshaft hanging in open air. The mineshaft contains two spider spawners, making this a great spot for an early mob farm or an unusual base build with natural scenery and vertical depth.
Cave That Cuts a Hill in Half
A cave that is lined up perfectly to cut this cherry grove hill in half down to the bottom. Not sure what it would be used for, but I think it's quite neat.
Heaven Above, Hell Beneath
At -2975, 225, there's beautiful scenery with a village next to a large cherry grove surrounding a mountain and more! But under the village, theres a deep pit where at the bottom theres several large lava pools, deep dark, and an exposed mineshaft with a cave spider spawner immersed in a lava flow.
Exposed Cave ‘eye’ with Lava-suspended Mineshaft
Spawn relatively close to an exposed cave shaped like an eye opening to the surface, with a hanging mineshaft suspended above lava. The formation is reminiscent of a small ravine, offering a dramatic and adventurous spot for exploration.
Lush Cave Spawn
You spawn in a taiga biome with a large, open entrance to a lush cave right at spawn, making early exploration and resource gathering easy.
Sparse Jungle Island with Deep Waterfall
There’s a lot to like about this seed: you spawn next to very tall cliffs and mountains, with a woodland mansion nearby, an above-water warm ocean ruin on a small island, and a mostly sparse jungle island featuring a continuous waterfall from the ocean down to Y:54, with several large water pools along the way.
Mountainside Exposed Lush Cave
A lush cave, fulled exposed on the side of a mountain.
