Minecraft Cave Finder

See the cave systems in your world before you dig. Enter your seed and pick a depth, and the map draws a slice through every cave and cavern at that Y level.

See the caves before you dig

Set your seed, pick a depth, and the map slices through the world at that height. Bright areas are open air, dark areas are solid stone. Drag the depth slider and the slice moves with it, so you can follow a cavern down or trace a tunnel back to where it surfaces.

This is not an estimate. The map runs the same terrain density function the game uses to decide whether each point is stone or air, so what you see is what generates. The one limitation is that it is a flat slice: a cave passing just above or below your chosen Y will not show until you move the slider to meet it.

Picking a depth

Y=11 is the default because open cave volume peaks there, and it is above the lava seas that fill the deepest levels. Y=-52 and below is deep dark country, worth checking alongside the biome layer if you are hunting an ancient city. Near Y=40 to 60 there is much less cave, but what remains is mostly ravines and the shafts that connect to the surface, which is the fastest way to find an entrance rather than digging in blind.

Frequently asked questions

How do I find caves in Minecraft using my seed?
Enter your seed and set the Cave depth slider to the Y level you care about. The map draws a horizontal slice through the world at that height: lit areas are open space, dark areas are solid rock. Slide the depth up and down to follow a cavern system through the world.

What Y level has the most caves?
Around Y=11, which is why the slider starts there. Open cave volume peaks in the range from about Y=0 to Y=30, and thins out both below Y=-40 and above Y=40 as you approach the surface.

Is this the real cave layout or an estimate?
It is the real layout. The map evaluates the same terrain density function Minecraft uses to decide whether a block is stone or air, so a tunnel drawn here is a tunnel in your world. It is a single-height slice rather than a 3D view, so a cave that passes just above or below your chosen Y will not appear until you move the slider.

Can I find a specific cave type?
Not directly. Cheese caves (big open caverns), spaghetti caves (long winding tunnels) and noodle caves (thin ones) all come out of the same density function, so they show up together. In practice the shapes are easy to tell apart on the map: large blobs are cheese caves, thin threads are spaghetti and noodle caves.

Where is the deep dark?
Deep dark generates in the deepest cave regions, roughly Y=-52 and below. Set the slider near the bottom and turn on the biome layer, and use the ancient city finder to pin the cities inside it.

Does this work for Minecraft Bedrock Edition?
Yes. Use the Java / Bedrock toggle above the map. Be aware the two editions are not interchangeable: since 1.18 they share terrain and biome generation, so the landscape for a given seed looks nearly the same, but structures like villages and strongholds use edition-specific placement and end up in different places. Bedrock also uses 32-bit seeds where Java uses 64-bit.

Is my seed sent to a server?
No. The whole map is computed in your browser with JavaScript. Your seed never leaves your device, there is no account, and no download is necessary.

Can I share a link to what I am looking at?
Yes. The address bar updates as you pan and zoom, so you can copy the URL at any time, or press Copy link. Anyone opening it lands on the same seed at the same position and zoom.

What do the grid lines mean?
The fine grid is chunks (16x16 blocks), which is the unit slime chunks and mob spawning work in. The heavier grid is regions (512x512 blocks, or 32x32 chunks), which is the unit Minecraft uses when deciding where to place structures. Brighter lines through the middle mark the world origin at X=0, Z=0.
