Here! I am going to express The hidden heaven on earth, from my viewpoint 
Bioluminescence beach!!
There's is a beach in mudhdhoo island of Maldives that glows at night.
This glow in dark is basically a natural phenomenon called 
Bioluminescence 
Bioluminescence in deep sea creatures is due to the presence of symbiotic bacteria
 in their photophore cells.

Bioluminescence: living lights ,lights for living!
