There is a taxi stand on the right side before you enter the Duty free shop when exiting Bali airport (international terminal). Prices for one ride to Seminyak/Kerobokan area should be around [currency_sel]140000 IDR[/currency_sel] ++. At night time they might refuse to give you the fixed prices that are written on the board but instead demand a small surcharge. We do not recommend to get in trouble with a taxi driver 😉
