Datapack Atmo Alex'sCaves

Atmo Alex’sCaves, a floating skyland above The End

Atmo Alex’sCaves is a Java Edition Minecraft datapack for Minecraft 1.20.1 that transforms the space above The End into an unusual floating skyland. Built around the Alex’s Caves mod, it places the mod’s distinctive cave biomes in the sky, creating a surreal destination suspended over the void rather than beneath the Overworld.

This compact exploration experience turns vertical movement into the main challenge. Players can search for a hidden route, reach the elevated terrain by jumping beyond The End’s build limit, and explore an environment shaped by Alex’s Caves aesthetics. For a Minecraft server, our BoxToPlay team recommends it as an atmospheric Easter egg and a memorable reward for adventurous players.
