Twin Cavern

Twin Cavern is technical cave diving, not a recreational add-on: divers descend Danajon Bank's vertical wall and drift to the entrance of the first cavern, with the site running past 45m. It demands cave or technical certification and full planning — this isn't a walk-up dive.

For technical divers visiting Bohol specifically for this kind of diving, it's a genuine drawcard; for everyone else, Danajon Bank's shallower sites are the better fit.
