Tirta Gangga, also known as the Water Palace, is the former royal palace of the Kingdom of Karangasem located in Eastern Bali. The one-hectare complex was built in 1946 by the late King of Karangasem but was almost completely destroyed by the eruption of Mount Agung in 1963, having since been rebuilt and restored.
A reservoir inside the palace complex holds the spring water delivered by a pipe system from the nearby village of Amlapura. There is also an underground pipe system which leads to the upper swimming pool where it emerges through the mouth of a demon at the corner of the pool. From here the water flows over lower-level pools, fish ponds and fountains.
It’s busiest between 12 – 3 pm and there is an extra IDR 10k fee if you want to swim in the pool.
