The Most Exciting Excursion in East Java, a Midnight to Mount Bromo.
The Bromo Tengger Semeru National Park covers some 800 square kilometers in the center of East Java. It is the largest volcanic region in the province and there stands Mount Semeru, which rises 3676 meters above sea level. At its northern end is the spectacular Tengger Caldera, Java's largest, with its 10 km barren desert-like sea of sand. Within the caldera rise the deeply fissured volcanic cones of Batok and Bromo, the latter is active with a cavernous crater from which smoke blows skyward.
