27. The Bioluminescent Bays
There are several bioluminescent bays around the world where the water glows with a blue light when disturbed.
This is due to the presence of microorganisms called dinoflagellates that emit light when they are moved. These bays can be found in places like Puerto Rico, the Bahamas, and Australia, and they are a popular tourist destination for those who want to experience this natural wonder.
