Mt Bromo is an active volcano that lies in the middle of Tengger caldera, a crater of fine volcanic sand in East Java. It sure is a great spot for those looking for some adventures in Indonesia. At 7,641 feet, it is not the highest peak of the massif, but it is the best known. The top of the volcano has been blown off and the crater inside constantly belches white sulfurous smoke. Travelers wake up in the early hours to stand on the rim of the caldera at sunrise for an ethereal view of Mount Bromo and the Sea of Sand.
