When we swam into the part of the cave where the salty rock drops down closer to the surface of the water, that rocky kind of roof soars back up into darkness...and sleeping bats. The contrast between the bats and the dark heights of the insides of the cave and the weightlessness of the light aqua clarity of the water that has built up in the cave is quite wild and ridiculously cool to experience...just drifting inside the cave, enjoying it all.
