‘Hidden in the dense jungle of the Peruvian Amazon is a percolating, roiling river. The steaming turquoise waters that can reach up to 200 degrees Fahrenheit are guided by ivory-colored stones and guarded by 60-foot walls of lush forest and vegetation. Locals believed that the river was sacred and that the hot waters held healing powers, and shamans incorporated it into medicines.’
