Often, it seems like many Instagram posts or advertisements use a filter so that the seawater looks more turquoise and clear. But in reality, they are not as turquoise as they seem. In my personal experience, this would happen especially a lot in Mexico, Central America, the Philippines, Vietnam, Thailand, or Indonesia, whereas it is usually not as exaggerated in the Caribbean, Australia, beach areas next to the desert(Red Sea), etc.
I usually look up street views or 360-degree views on Google Maps, since they don't usually use filters there. I would also. However, that might be a way to check whether those places have turquoise water, but it can't be a way to find which place has the most turquoise & emerald & clear water.
What might be the best ways to find turquoise water?
