Features intended for release in the second Caves & Cliffs update for this year (1.18) can still be accessed via the Caves & Cliffs Prototype Data Pack.  

What is the Caves & Cliffs Prototype Data Pack? 

This data pack allows you to use features that are under development and intended to be released in the second Caves & Cliffs update in your Minecraft: Java Edition worlds.  

How do I access the Caves & Cliffs Prototype Data Pack?

• Launch the game, go to the "Create New World" screen, and click the "Data Packs" button 

• Drag the downloaded zip file onto the Minecraft window
• The game will ask you if you want to add the data pack - click "Yes"
• Click the play arrow on the data pack that just appeared in the list - this will move it to the list on the right-hand side of the screen

• Click the "Done" button and continue creating your world as normal

How do I know if my world has experimental features enabled?

To identify if the Caves & Cliffs Prototype Data Pack is active in your world, refer to “Options” >  “Resource Packs”.

Will it be possible to use the Caves & Cliffs Prototype Data Pack in my pre-existing world?

The data pack can only be used in newly created worlds.

Will it be possible to upgrade worlds that use the Data Pack to the full Caves & Cliffs Part 2 release later this year? 

Upgrading to the Part 2 release (1.18) will not be supported for worlds that use the Caves & Cliffs Prototype Data Pack.
