Gunung Bromo is an active volcano and part of the Tengger massif, in East Java. At 2,329 meters (7,641 feet) it is not the highest peak of the massif, but it is the most well known.
The area is one of the most visited tourist attractions in Indonesia and Java. The top of the volcano has been blown off and the crater inside constantly belches white smoke.
It is surrounded by the Sea of Sand of fine volcanic sand. The overall effect is unsettlingly unearthly.
