What you can see on the Mount Bromo cam
The camera looks across the caldera in 4K from the rim, which is the classic framing: the sand sea in the foreground, Bromo steaming from its truncated crater in the middle, the perfect green cone of Batok beside it, and Semeru on the horizon behind — a second volcano, higher and far more active, that sends up an ash puff every hour or so. The sand sea fills with cloud overnight and drains as the sun rises, so the two volcanoes often appear to float. Bromo's own plume is thin and continuous rather than explosive; when the volcano is restless it thickens and turns grey.
Bromo, Batok and Semeru over the sand sea
From a viewing terrace on the rim of the Tengger caldera, this 4K livestream takes in one of the best-known volcano views in Indonesia. The stone steps and railing of the terrace run in from the right; below them the grey sand sea spreads across the caldera floor. In the middle, Bromo's broken crater often sends up a white plume, the ribbed, perfectly shaped cone of Batok stands in front of it, and far behind, Semeru rises above everything, often with a small puff of ash drifting from its summit.
Early morning, when mist still lies in the caldera and the light comes low across the ridges, is the time the terrace fills with visitors.
A crater with a temple at its foot
The Tengger people, who live on the caldera rim, are Hindu, one of the few communities in Java that never converted. Their temple, Pura Luhur Poten, stands on the sand sea at the foot of Bromo, and once a year at the festival of Yadnya Kasada they climb the cone in the dark and throw offerings of fruit, rice, flowers and livestock into the crater. The tradition traces back to a legend of a princess who promised her fourteenth child to the mountain. The date moves with the Javanese calendar and falls around the full moon of the month of Kasada.
When to watch Mount Bromo
Java is seven hours ahead of UTC. Sunrise is the moment everyone waits for: the cameras and the viewpoints both face east, the sand sea is at its cloudiest and the light is at its best. By late morning the caldera is often closed in, and the wet season from November to March can hide it for days. The dry season, from May to September, is the safest bet.
Around Mount Bromo
The whole area is Bromo Tengger Semeru National Park. Semeru, 3,676 metres and the highest mountain in Java, is the same park; Penanjakan and the other rim viewpoints look down on Bromo from the north-west. The nearest towns are Probolinggo on the coast and the villages of Cemoro Lawang on the rim itself.
Visiting Mount Bromo
From the rim, a road and then a walk across the sand cross to the foot of the cone, with 250 steps to the crater rim; horses can be hired for the flat part. The crater edge is narrow and unfenced in places. Access is closed when the alert level rises, which happens regularly.
