Goa Gajah
Goa Gajah is one of the island's most impressive archaeological sites, located south of the Bedulu village, a region famous for its collection of historical sites. The temple complex is within a six-kilometre drive south of central Ubud and an hour's drive northeast from the provincial capital of Denpasar.
Down a flight of stairs, you will discover a relic-filled courtyard and the main 11th century 'cave' in which you can enter to view rock-wall carvings and a meditational site, while out on the perimeter are a Hindu temple and an impressive bathing pool with fountains, excavated back in 1954.
