Caves & Cliffs Part I
Dive deep into a reshaped underworld of dripping stone and lush caverns.
Caves & Cliffs Part I represents a monumental expansion of the Minecraft world's verticality and underground ecosystems, released in June 2021 as the first half of a larger update. This release fundamentally altered how players explore the deep stone layers beneath the Overworld surface, introducing vast new cave biomes and changing the generation rules for ancient structures like mineshafts. It serves as a foundational chapter in the game's ongoing evolution, shifting the focus from flat terrain to complex, three-dimensional subterranean labyrinths filled with both danger and rare treasures.

Lore & Background
Conversely, Dripstone Caves introduced a harsher, more geological beauty, characterized by massive stalactites and stalagmites that can pierce through the floor or hang precariously from the ceiling. These formations are not merely decorative; they possess mechanical properties that can harm explorers who wander too close. The update also revealed the presence of Copper Ore, a resource that weathers over time, hinting at a world where the passage of time physically alters the landscape even after it has been mined.
In Their Own Story
The torch flickered, casting long, dancing shadows against the walls of obsidian and deepslate. Below, the air grew humid and cool, smelling faintly of wet moss and ancient water. A soft splash echoed from a pool hidden in the gloom, followed by the distinct, curious chirp of an Axolotl peeking out from behind a cluster of azalea leaves. The explorer paused, realizing that this was not the barren void they had expected; it was a living world beneath their feet, waiting to be mapped.
Reader's Guide
The narrative arc of this update begins with a complete overhaul of how caves generate. Instead of simple tunnels, the game now creates massive, interconnected caverns that stretch for hundreds of blocks horizontally and vertically. Explorers encounter two primary new environments: Lush Caves, which are filled with water, glow berries, and copper ore; and Dripstone Caves, defined by sharp stone formations. These biomes often replace the old cave systems entirely in newer worlds. The update also introduces Amethyst Geodes, rare structures containing crystalline shards that can be harvested for blocks and tools. Additionally, Copper Ore becomes a vital resource found deep underground, adding a new layer of mining strategy as players must locate these veins to craft armor and decorative items.
Did You Know?
- Axolotls are neutral mobs that attack certain aquatic mobs but are passive toward players; the glow squid is a passive mob added in this update, though it is a new variant of the existing squid rather than the first pass
- Copper blocks change color over time as they oxidize, a process that can be halted and preserved by applying Honeycomb wax.
- Amethyst Geodes can generate partially exposed on the surface, such as on beaches or in open air, making them one of the few structures that can appear both underground and above ground.
- The update did not increase the world height limit; that change came in Caves & Cliffs Part II (1.18), which raised the limit from 256 to 320 and fully introduced the new mountain generation.
