Bromo Tengger Semeru National Park

Bromo Tengger Semeru National Park is the only conservation area in Indonesia that has a 10 km sea of sand called Tengger, from which four new volcanic cones have emerged. Those volcanic cones are Mount Batok (2,470 m), Mount Kursi (2,581 m), Mount Watangan (2,661 m), and Mount Widodaren (2,650 m). However, Mount Bromo is still the only one that is active. Temperatures at the top of Mount Bromo range about 5-18 degrees Celsius. Heading south of the park is a rolling upland plateau divided by valleys and decorated with several scenic lakes reaching to the foot of Mount Semeru.
