If you are into scuba diving you might want to visit Cenote Angelita in Mexico for a really amazing archaeological discoveries experience. Dive deeper, the water will turn from pure to salty. According to some sources, the river is a layer of hydrogen sulphide. It is really amazing just for the fact that the sungai (river) is under the sea (dibawah laut). Well, the title of my post (Sungai dibawah laut) is a translated version for Underwater river in Bahasa Melayu.
