The ones we been into were within a couple of hours near Cancun as well but it was snookering not scuba. Our guide took us to what looked like a little opening from a pool of dirty water from the surface.As soon as we swam through the hole, the depth was 20-30' of crystal clear water. We basically swam through a tunnel into a bigger tunnel. The guides were the only ones with the flash lights, but as we stop to catch our breath, he warned us that the light will be off for a few. Like Don said, blackness. Its something I had never experience. A real freaky feeling. WE ended up climbing out of a big hole from the ground way on the side of the hill. We spent a good two to three hours in there. There are little fishes and shrimps in that water. How do they see or eat?

Thinking about it years later, what happens if the guide takes the wrong turn?

That darkness is scary. Remember a couple of years back there was a ship wreck survivor and days later, the diver found this man alive with his body submerge in water in some parts of the ship breathing from a trapped air pocket. I can't survive through no more then 5 minutes of that. This man did it for days.
