Total cave length (for caves of 1 km and above): 432.968 km.

If you don't see the cave you want, but you know it should be in the England section, remember that this list only shows caves with at least 1 km length of natural passage. Other caves may show up in the list of deepest caves in England.

However, if you are looking for a specific cave that does have at least 1 km length of natural passage, and should be listed here, please let me know about it so I can update the database.
