Ijen Crater is the biggest crater lake in Java. The sulfur crater lake lies between a natural dams of deeply etched rock. It is 200 meters deep and contains about 36million cubic meters of steaming acid water, shrouded in a smelling swirling sulfur cloud. Inside the crater the different color and size of stones are found. Indeed the crater of Ijen is beautiful garden of stone as well.The view of sulfur miners who climb and go down to the crater is also amazing. A man puts about 10 kg of yellowish stone in to his basket, before he descends the mountain slope to sell his load, carrying the same basket, going in the same direction, digging the same mineral. It is the natural picture that can be seen everyday.
