> They were diving upstream in the system so they were having to swim against the current,
or pull themselves along the walls. Some of the cave is fairly constricted and other points
aren’t. I gather the actual diving section was about 1.5km, about half of which was
completely flooded and about half of which was open.
They estimated that a round trip is 3 hours.
