Experience the remarkable 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 still active with a cavernous crater from which smoke blows skyward. Temperatures at the top of the Mt Bromo range about 5-18 degrees Celsius. To the south of the park is a rolling upland plateau dissected by valleys and dotted with several small scenic lakes, extending to the foot of Mt Semeru. Many visitors to the park choose to walk while they are here. 

There are clearly marked tracks across the sand sea that leads to the foot of Bromo. Alternatively, you can rent a jeep or hire a horse from Cemoro Lawang to get around Bromo Tengger Semeru can be reached by private and public vehicles from Surabaya or Malang in East Java. Sriwijaya Air flies twice daily to Malang from Jakarta.  There are multiple ways to get into the park. Visitors can come from Probolinggo, in the north west arrive through the village of Ngadisari. Or take the northeast approach via Pasuruan and the village of Tosari. 

The third, the more difficult approach is via Ngadas, which is best traveled on the way down. The Probolinggo approach is the easiest and by far the most popular route, especially if traveling by public bus. Wonokitri is the closest and the easiest approach if you are coming by private vehicle from Surabaya (5 hours journey). To get closer to Mt Bromo you must rent 4x4 vehicles (there are many 4x4 vehicles available for rent there). Most tour groups from Surabaya stay overnight at Tretes, where there are a number of hotels, as there are in Malang, which has the added advantage of having an airport.  Alternatively, you can contact a travel agency to arrange your trip
