Goa Gajah, Ubud
Concierge.com's insider take:
The "Elephant Cave," discovered by a farmer in 1923, is a temple that dates back to the 11th century. Worshippers likely purified themselves in the rectangular bathing pools in front, where water spouts from jars held by six stone nymphs. Visitors enter through the mouth of a menacing demon face. Inside, you'll see a statue of Ganesha, the elephant-headed god, as well as three lingams (phallic fertility symbols) and three yoni (the female equivalent). The cave is in a valley outside Ubud and near the town of Bedulu.
