This river is known as the Enchanted River in the Philippines and was only discovered recent years. None knows where the water comes from. This remains a mystery. The river has crystal-clear waters, such that you can see the riverbed even at the deepest part.
One of the most unique features of the enchanted river is its unfathomable depth. No one has ever reached the bottom. This is why many tourist swim in the shallow part of the enchanted river area with water’s shade range from aquamarine to blue. The dark blue color in the river simply means the water is very deep. At exactly 12 noon the caretaker rings the bell requesting everyone to get out from the water as is “feeding time”. The “hymn of Hinatuan” is played and a massive school of fish pops out from nowhere. The fishes gather near the mouth of the river as the caretaker feeds them some leftovers of shrimp, rice, and other food scraps. (Source)
Oh that’s so pretty
Fun fact: the fish don’t hunt/feed themselves anymore because of the feeding time. They just wait to get fed
Also you can’t swim in the dark blue part because someone tried to see how far down they could swim and ended up getting stuck and drowning
