Natron is the scariest lake on earth that is located in Tanzania. This scariest Natron lake has a huge proportion of sodium carbonate. The high volume of salt present in this lake transforms the dead animals into statues, through the calcification process. This lake is also known as, ‘Petrifying Lake’ because its color looks red due to high alkaline accumulation, especially in summers. The best time to visit this area is June to August.
