A Bioluminescent Bay is a body of water that has all the proper combination of conditions for micro-organisms known as dinoflagellates to exist.  Because of these mico-organisms, when the water is disturbed it glows a brilliant neon blue.  The environment that must be present is such a chain of events it is amazing these areas exist at all. 

I recently had the experience of seeing this phenomenon when I was in Puerto Rico.  I took the adventure to Laguna Grande near the El Yunque rainforest, where I took the two hour bio bay kayaking tour.  For a first time kayaker it was a long strenuous trip.  Most areas were very narrow and hard to navigate, but looking back on the experience and realizing the greatness of being able to see this amazing phenomenon was all worth it.

I was not able to take any pictures, because the light may disturb and kill the organisms in the environment, but see the video below for a view of the kayaking area.
