I want to recommend Dewa Alit as an excellent driver. My family of four (daughters were 10 and 12) met Dewa about 12 years ago during a month-long stay in Bali and we've kept in touch since then. He now has two darling little children whom he supports via driving tourists around. He's absolutely reliable, on time, and knows many quiet spots to show you. He charges between $32 and $40/day depending on the type of car you need. You can reach him at dewa_alita@yahoo.com or by phone at 62 0 812 46 99691. Feel free to email me to get more information about Dewa. You'll be charmed by him.
