The volcanic Bromo region in Java, Indonesia is a lunar-like landscape with surreal beauty. Rising from the guts of the ancient Tengger caldera, Gunung Bromo is one of the multiple volcanoes to have emerged from a vast crater - Bromo, Kursi, Batok and Semeru. This vast system of volcanoes stretching over 10km is surrounded by a sea of ashen volcanic sand, called the Segara Wedi (Sand Sea).
Kawah Ijen is an active volcano standing tall at 8530 feet in East Java, Indonesia. Inside the crater of the volcano lies the largest sulfuric acid lake in the world (650 feet deep). Exquisitely pristine looking, the lake is the most toxic water body, with a pH level of less than 0.3 and the crater is the site of a gruelingly labor-intensive sulfur mining operation.
This is a real life hell and it smells of sulphur!
