Mount Batur

Gunung Batur

Mount Batur is an active volcano in central Bali's Kintamani highlands, rising 1,717 metres inside a 13-kilometre caldera with a crescent lake at its base. From a helicopter, twenty minutes north of Nuanu or thirty from Nusa Dua, the double-caldera structure is finally legible in a single frame — the cone, the lake, the lava fields, and the rim road around all of it.

The place

What is Mount Batur

Mount Batur — *Gunung Batur* in Indonesian — is one of Bali's two great volcanoes, the smaller and more active sibling of mount-agung. The current cone sits inside a much larger caldera formed by two prehistoric eruptions, roughly 29,000 and 20,000 years ago, that emptied the original magma chamber and collapsed the summit. What's left is an outer caldera about 13 kilometres across — one of the largest and most distinct on the planet — with the present-day cone risen in its centre and a crescent-shaped crater lake, Danau Batur, lapping its eastern base.

The volcano has erupted at least 26 times since 1804. The 1917 eruption is the one Balinese collective memory still references; lava reached the edge of the village of Batur but stopped at the temple wall, which the community read as a sign and rebuilt the temple uphill on the caldera rim.

Today the mountain is best known as a sunrise trek — climbers start at 4 a.m. to reach the summit for the moment when the sun rises behind Mount Agung and Lombok's Mount Rinjana. The helicopter version is the same view without the hike.

The aerial view

From the air

The helicopter approach to Mount Batur is the most geologically satisfying flight on the volcanoes route. At cruise altitude you finally see the system rather than just the cone.
