Hawaii’s Kauai Island has a natural swimming pool, quite impressive but also extremely dangerous. Its regular name is “Queen’s Bath”, but most call it “Pool of Death”!
The “pool” is surrounded by rocks, with its waters at one time calm and the other furious.
Essentially, it is a natural formation that ends up at the bottom of an aquatic body through which water passes.
It is worth noting that according to the “Centers for Disease Control” report, in the United States, on average, 3,536 people died from drowning annually from 2005 to 2014, which equates to 10 deaths each day!
