The Bromo Tengger Semeru National Park is best known for its awesome scenery of a vast, ancient volcanic crater and a host of picturesque volcanoes that have emerged from it. The park is named after two mountains, Mount Semeru, Mount Bromo and the Tengger people who inhabit the area. Semeru is the highest mountain in Java as well as one of Indonesia’s most active volcanoes. The smouldering cone of Bromo stands in a sea of volcanic sand, surrounded by the towering cliffs of the crater’s edge.Rising from the guts of the ancient Tengger caldera, Gunung Bromo (2329m) is one of three volcanoes to have emerged from a vast crater, stretching 10km across. Flanked by the peaks of Kursi (2581m) and Batok (2440m), the smouldering cone of Bromo stands in a sea of ashen, volcanic sand, surrounded by the towering cliffs of the crater’s edge. Just to the south, Gunung Semeru (3676m), Java’s highest peak and one of its most active volcanoes, throws its shadow – and occasionally its ash – over the whole scene.
