The temple was built in 1633 to worship the triad of gods Brahma, Vishnu, and Shiva, as well as the lake deity, Dewi Danu. Her gilded statue was unveiled in 2017 and is located on the opposite side of the lake from the temple.
The name of the temple literally translates as "Lake's Head."
The temple consists of four shrine groups. Four gates are installed on the four cardinal directions.
Inside the temple, there is typical tiered Balinese architecture and three main pyramid-shaped sanctuaries dedicated to Brahma, Vishnu, and Shiva. Tourists are allowed to enter the temple, but the central courtyard, used for festive ceremonies, is closed to them.
The image of Ulun Danu Beratan Temple is featured on the 50,000 rupiah banknote.
If you want to take a boat ride on the lake, you can rent a rowboat or a motorboat here, or even go fishing. Swimming here may not be pleasant as the water is quite cold. In some areas, the lake's depth can reach 35 meters.
During the dry season, the water in the moat around the temple may dry up, but during the rainy season, it is always surrounded by water.
There is a small zoo on the park grounds near the temple where you can see exotic birds and bats.
