Cavernous is a vanilla-like datapack (packaged as mod) that adds 14+ new cave biomes, New structures, features and advancements and much more. From variants of the default caves, to biomes unlike any you've seen before, you'll never run out of things to explore in Cavernous' new underground.
BIOMES:
Volcanic Caves - Lava filled caves that house some great rewards but far greater risk. Also contains a new custom block called the geyser block, which launches you high in the air.
Splattered Caves - Standard caves with much more frequent placement of andesite, diorite, and granite.
Marshy Caves - Found under swamp biomes, these caves provide muddy terrain and giant sprawling roots hanging from the ceiling from the trees in the biomes above
Marble Caves - Like the standard caves except with walls of diorite and calcite.
Lush Dripstone Cave - A mix of the two vanilla cave biomes
Tropical Caves - Under the jungle biome a new cave generates that houses ancient temples and lush forests. Be weary as it houses some poisonous secrets.
Icy Caves - Found under mountains and cold biomes, these caves prove treacherous, from the slippery floors to the ever-present danger of powder snow. Extra ores and cave systems can be revealed by looking through layers of ice. It also spawns strays.

GEYSER DISCLAIMER
If you are using Cavernous on a server, you must have command blocks enabled. This is only so the geysers can generate and does not give anyone access to command blocks. You can do this by going to the server.properties file and setting "enable-command-block" to true.
You also cannot use other datapacks that unlock all recipes since it breaks certain features. An alternative datapack can be found here: https://wasdbuildteam.website/data-packs/unlock-all-recipes/
UPDATING FROM OLD CAVERNOUS VERSION
In order to update from a version released before Minecraft 1.20, you must delete the old Cavernous datapack in your world's datapack folder and then put in the new datapack (the one this read me belongs to) and drag the "CavernousCompatibility.zip" from the same folder into the datapack folder as well. You only have to do this once, every other time you upgrade to a new version the compatibility pack will still work.
