Mount Batur is the most climbed volcano in Bali and one of its most active. Its summit stands at 1,717 meters, rising about 700 meters above the waters of Lake Batur from the floor of an enormous caldera. The pre-dawn trek to the crater rim is the island's classic sunrise outing, accessible to most reasonably fit walkers and rewarded with views of Agung, Abang and, on clear days, Rinjani.
Batur's first documented eruption was in 1804, and it has erupted frequently since, most recently around 2000. In 1926 an eruption buried the village of Batur and its great temple at the foot of the mountain; the villagers carried the surviving shrine uphill and rebuilt on the caldera rim, where Pura Ulun Danu Batur stands today. Black lava fields from the 1960s eruptions still spread across the caldera floor.
Most hikers start from Toya Bungkah or Pura Jati around 4 a.m., climbing by headlamp over loose volcanic gravel. The ascent takes roughly two hours. At the top, steam vents drift from the crater, guides cook eggs in the volcanic heat, and the light slowly comes up over the lake and the long ridge of the caldera wall.
Highlights
- Sunrise over Lake Batur and Mount Agung
- Steaming vents along the crater rim
- Black lava fields from past eruptions
- Hot springs at Toya Bungkah after the climb
Good to know
- Check the current alert level with MAGMA Indonesia (PVMBG); summit access can close when activity rises.
- Climb with a guide from the local guide association; this is the standard arrangement at the trailheads.
- Wear shoes with real grip, as the descent on loose scree is harder than the climb.
- Bring a warm layer for the summit, where the wait for sunrise can be cold and windy.
