Use locate command
Use
/locatebiome regions_unexplored:biome_name to find specific cave biomes. Note that cave biomes may be far from spawn.Explore below Y=0
Cave biomes generate in deepslate layers. Explore underground cave systems below Y-level 0 for the best chance of discovery.
Look for visual cues
Unique particle effects, lighting, and vegetation colors indicate you’ve entered a special cave biome.
Mining strategies
- Ancient Delta
- Bioshroom Caves
- Prismachasm
- Redstone Caves
- Scorching Caves
Harvest unique aquatic plants and mineral pools. Bring water breathing potions for extended exploration. Axolotls can be captured for breeding.
Cave biomes can overlap with vanilla cave types like dripstone and lush caves, creating hybrid areas with features from both.
