The Belize Barrier Reef

The underwater world is an alien world.  Am I still on earth?  Gravity evaporates.  I must kick harder to gain entrance to the kaleidoscope of neon below me.  Finally, the cool water encloses me, and I am bathed in magic.

The Belize Barrier Reef is one of the world's largest coral reefs, extending from Cancun all the way down to Honduras.  The water is still very clear and the reef is very much alive.
