Klungkung is the smallest regency in the Bali province. This busy market town on the main route to Besakih and Amlapura is steeped in history and has some noteworthy sites. It is bordered by the stony Unda River with its great expanse of weirs protecting the surrounding villages during flood times. In the east side, the landscape is still scarred by the lava streams of the eruption that occurred in 1963. Bali’s smallest district Klungkung is located between Gianyar and Karangasem, and includes the island of Nusa Penida, Nusa Lembongan and Ceningan.
