A well-signposted fork in the road north of Tampaksiring leads to the popular holy springs at Tirta Empul, discovered in AD 962 and believed to have magical powers. The springs bubble up into a large, crystal-clear pool within the temple and gush out through waterspouts into a bathing pool.
The waters are the main source of Sungai Pakerisan (Pakerisan River), the river that rushes by Gunung Kawi only 1km or so away. Next to the springs, Pura Tirta Empul is one of Bali's most important temples. Come in the early morning or late afternoon to avoid the tourist buses. You can also use the clean, segregated and free public baths here.
