If you don't see the cave you want, but you know it should be in the all regions section, remember that this list only shows caves with at least 60 m depth of natural passage. Other caves may show up in the list of longest caves in all regions.

However, if you are looking for a specific cave that does have at least 60 m depth of natural passage, and should be listed here, please let me know about it so I can update the database.
