Nusa Dua is located 40km south of Denpasar, the provincial capital of Bali. Access is easy from the Kuta area 20-30 minutes and Jimbaran 15 minutes on the main southern route called Jalan Bypass Ngurah Rai, which becomes Jalan Bypass Nusa Dua as it approaches the enclave.
The international airport is about 20 to 30 minutes by car and a pre-paid taxi fare from there will cost between Rp 95,000 and 110,000. If you are staying here, then your hotel will no doubt arrange to pick you up at the airport.
Public transport is far from regular in the area, but some bemos from Tegal terminal in Denpasar do ply the main bypass.
