Bratan Lake

Lake Bratan and the Ulun Danu Bratan Temple

Lake Bratan, located in Bedugul, Central Bali, is one of the island’s three main volcanic crater lakes. It sits at an elevation of about 1,239 meters above sea level, surrounded by cool mountain air and often covered in light mist. The lake plays an important ecological and spiritual role in Bali’s highlands, providing water for farming and acting as a reservoir for the island’s traditional subak irrigation system.

On the western shore stands Pura Ulun Danu Bratan, a water temple dedicated to Dewi Danu, the goddess of lakes and rivers. Built in the 17th century during the rule of the Mengwi Kingdom, the temple complex includes several shrines (meru), the tallest with eleven tiers, honoring Shiva and Parvati. A Buddhist stupa on the grounds reflects the coexistence of Hindu and Buddhist beliefs in Bali’s history.

The Lake’s Role and Characteristics

Lake Bratan covers roughly 375 hectares and reaches depths of up to 48 meters, depending on rainfall and season. Its waters are considered sacred, and the lake serves as a key source for irrigation throughout the central region. The area is cooler than the lowlands, with average daytime temperatures between 18–24 °C.

Because of its central position, the lake has long been part of the island’s agricultural infrastructure — linking the highland water sources to downstream rice terraces through the subak system, a UNESCO-recognized cultural landscape.
