The lake is fed by volcanic springs rather than surface rivers, which maintains its mineral-rich composition.
The water depth can reach up to 88 meters in certain sections of the caldera.
Mount Batur's caldera is a 'double caldera,' with the lake resting in the outer ring formed by the older, larger eruption.
The Trunyan village on the eastern shore practices a unique funerary rite where bodies are left to decompose under a sacred Taru Menyan tree, which supposedly neutralizes the odor.
The lake ecosystem includes endemic fish species and is heavily influenced by agricultural runoff from the surrounding terraces.
It is considered a sacred water body by the local Balinese Hindu population, essential for the spiritual balance of the region.
Danau Batur is a crescent-shaped caldera lake situated within the caldera of the active Mount Batur volcano in Kintamani, Bali. It is the largest lake in Bali, covering an area of approximately 16 square kilometers at an elevation of 1,031 meters above sea level. The lake sits at the foot of Mount Batur, which last erupted in 2000. Geologically, the caldera was formed by two major prehistoric eruptions, with the inner crater containing both the lake and the active cone. The surrounding landscape is characterized by solidified black lava flows from previous volcanic events. The water level fluctuates significantly based on seasonal rainfall due to the lack of a major outlet. Local residents primarily engage in inland fishing and small-scale vegetable farming on the fertile volcanic slopes. The area is designated as part of the UNESCO Batur UNESCO Global Geopark. The lake serves as a primary source of irrigation water for the subak traditional cooperative irrigation systems throughout the Bangli Regency.

Bring a windbreaker or warm layers, as temperatures drop significantly at this altitude compared to Bali's coastal regions.
Hire a local boat operator from the Kedisan or Songan docks to explore the lake surface, as swimming is restricted in many areas.
Confirm the weather forecast before visiting, as heavy mist often obscures the lake views by midday.
Over-reliance on self-driving navigation in heavy fog; engaging with unofficial touts at the docking areas for boat tours.
Dress modestly as the lake is a sacred site; keep noise levels low and avoid disposing of waste into the water.
