Mount Bromo is one of Indonesia's most famous volcanoes, with good reason. There is little trekking to be done, but a visit here will serve up one of the most dramatic sunrise photos you have ever taken. From Gunung Pananjakan (2,753m), watch the sun rise with Bromo and Batok smouldering in the crater below, and Java’s highest peak Semeru brooding and smoking in the background.
Mount Bromo is in Bromo Tengger Semeru National Park area. This national park is named after its two mountains, Mount Semeru (the highest in Java at 3,676m), Mount Bromo (the most popular) and the Tengger people who inhabit the area.
Mount Bromo (2,329m) is easily recognized as the entire top has been blown off and the crater inside constantly belches white sulfurous smoke. It sits inside the massive Tengger caldera. with a diameter of approximately 10km, surrounded by the Laut Pasir (Sea of Sand) of fine volcanic sand. The overall effect is unsettlingly unearthly, especially when compared to the lush green valleys all around the caldera.
The major access point is Cemoro Lawang (also Cemara Lawang or Cemora Lawang - blame the East Javanese accent!) at the northeastern edge of the caldera, but there are also trails from Tosari (northwest) and Ngadas (southwest). The village of Ngadisari, on the road from Probolinggo about 5.5km before Cemoro Lawang, marks the entrance to the national park. Both Cemoro Lawang and Ngadisari are rather picturesque, with brightly-painted houses and flower beds outside.
