East Bali
The Eastern part of Bali is the most mountainous area of the island. The highest point in Bali, Gunung Agung (literally means Holy Mountain), is located here. And the Mother Temple of Bali, the Besakih Temple, is located at the foot of Mount Agung. This is the Mount Olympic of Bali, and you can find here various manifestations of Bali's religious beliefs. The Klungkung area is also historically significant, having served as a focal point of art and culture in the Gelgel dynasty. The roof of Kertha Gosa, the court room of the Klungkung kingdom, is dramatically painted with thousands of panels, telling the story of justice.
A long stretch of beaches marks the East side of Bali - diving, snorkelling, spectacular sunset, sun bathing, etc. Tenganan, a village of the Bali Aga people, is also here, just west of Candidasa, where you can see a mysterious water temple submerge from the water.
South Bali In South Bali, from Denpasar to Kuta to Nusa Dua, you can find a wide variety of things. Traces of the Badung Raja of Puputan War fame still exist. Beautiful, tranquil beaches gracefully integrate with the world's most sumptuous and luxurious hotels in Nusa Dua. And then there is Kuta, where everything you want as a tourist and everything you hate about tourists coexist.
West Bali Most of West Bali areas are not as popular as the other parts of Bali. (Hint: for those who truly say that they want to get away from other tourists...) Gilimanuk, at the Western tip of Bali, is the gateway to Java. The wildlife of Bali is preserved in the Bali Barat National Park. Also found here is the tomb of Jayaprana, a 17th century king whose Romeo and Juliet style love story is immortalized by folklores in Bali.
