Mt. Bromo is a volcano in East Java (sitting next to its twin, Mt. Batok) not far from the major city of Surabaya. To visit requires a combination of van, jeep and horseback--arriving in the early morning for the trek across the Sand Sea (formed from past eruptions) to the base of Mt. Bromo. A series of steps lead up the volcano to its narrow rim where you can enjoy the sunrise view, feel the power of its vibrations and smell its burnt-sulfur gaseous emissions.
