While Bali's other temples may be larger or more jaw-dropping, Tirta Empul, which can be translated as "Holy Water Spring," possesses a unique serenity that cannot be matched. This active prayer site inspires both Balinese Hindus and visitors of different beliefs. While there are several shrines and other structures on the premises, the temple's tranquility is best seen in the large rectangular pool at the complex's center. You'll see worshipers enter the water to pray, so be respectful of the Balinese customs and do not disrupt them. Travelers, too, are welcome to enter the water, known for being a holy mountain spring. Keep in mind, though, that you're expected to enter the water fully clothed (and must wear a sarong as well; they are available to rent for free on-site), so visitors suggest bringing a change of clothes along.
