Best natural wonder closest to magic? They're actually real, but really rare!! I got to go to one in Fajardo Puerto Rico; it was amazing! The water really does glow! Here's some info ( I DIDN'T WRITE IT) from different sites:

 

"Hidden along the Caribbean coast is one of the most spectacular Bioluminescent Bays in the world. The mysterious blue-green light is created by micro-organisms which thrive in an environment uniquely suited to their needs. A trip into the bay on a balmy night is a magical experience. Fish flash by in dark water, and a swim is like floating through stardust." - Captain Sharon Grasso

 

Why does the water glow?
This unique bay contains up to 720,000 single-celled bioluminescent dinoflagellates per gallon of water. These half-plant, half-animal organisms emit a flash of bluish light when agitated at night. The high concentration of these creatures (Pyrodimium bahamense) can create enough light to read a book from. Learn more by reading several articles on the bay. 

 

The Bioluminescent Bay in Vieques is, perhaps, the brightest in the world! with over 750,000 tiny dinoflagellates per gallon of water that light up when they are touched! Imagine a lake full of Tinkerbells fairy dust! Pure magic, the experience is actually indescribable.

The bioluminescent dinoflagellates Pyrodinium bahamense are a photosynthesis using plankton. They are one celled and measure about 1/500 th of an inch. The tiny burst of light it gives off is a hundred times bigger than itself. ( Above is merely an artists depiction of the glow) Each dinoflagellete bursts into light when it feels pressure against its cell wall. The light is given off in an instantaneous process; when you add the light bursts of 750,000 dinoflagellates per cubic foot of water together the effect is spectacular!

Almost all marine bioluminescence is (greenish) blue in color, for two related reasons. First, blue-green light (wavelength around 470 nm) transmits furthest in water. The reason that underwater photos usually look blue is because red light is quickly absorbed as you descend. The second reason for bioluminescence to be blue is that most organisms are sensitive only to blue light.

The luminescence of a single dinoflagellate is readily visible to the dark adapted human eye. Most dinoflagellates emit about 6e8 photons in a flash lasting only about 0.1 second. Much larger organisms such as jellyfish emit about 2e11 photons per second for sometimes tens of seconds. The intensity of luminescence by photosynthetic dinoflagellates is strongly influenced by the intensity of sunlight the previous day. The brighter the sunlight the brighter the flash.
