This visually stunning lake was created by the Mount Patuah volcano, and while it’s a local hot spot, it’s not widely known among foreign visitors. Kawah Putih means “white crater” in English because a high concentration of sulfur in the water has leeched the color from the rocks and sand, leaving everything white. Be warned, the smell of sulfur from the lake itself can be quite strong, especially around midday when the sun is at its hottest. But, although you can’t go swimming in this spot, it’s still well worth the trip. If you’re an animal lover, you’re in for a treat. A diverse range of animals make their home in the wilds surrounding Kawah Putih, including monkeys, Javanese mouse deer, and even panthers!
