Bromo Tengger Semeru National Park

Bromo Tengger Semeru National Park is a protected area on eastern Java, Indonesia, that encompasses a volcanic landscape including the Tengger caldera and Java’s highest peak, Mount Semeru.

The park’s signature sights are the broad volcanic plain called the Sea of Sand, the smoking crater of Mount Bromo (about 2,329 m) and Mount Semeru (3,676 m), Java’s highest mountain. Popular activities include sunrise viewing from designated viewpoints, jeep transfers across the Sea of Sand, and climbs to crater rims and higher summits.

The landscape was shaped by successive volcanic eruptions and continued volcanic activity. The area is also culturally important to the local Tenggerese people, who maintain traditional ceremonies at Bromo and surrounding temples.

The park lies in East Java and is accessed from nearby towns such as Probolinggo and Malang; typical visitor itineraries include overnight stays at villages on the caldera rim and pre-dawn trips to mountain viewpoints.

• Summits: Mount Semeru is the highest point in Java at 3,676 m and remains an active volcano; Mount Bromo has a crater that is frequently visited by tourists
• Best time to visit: sunrise viewpoints such as Penanjakan offer widely visited panoramic views over the caldera and Mount Bromo, making early mornings the busiest time
