Bali doesn't have a public transit network built for tourists, so most visitors rely on private transfers, ride-hailing apps, and fast boats between islands.
From the airport
A private airport transfer is the easiest way to start your trip — book ahead so a driver is waiting with your name at arrivals rather than negotiating with touts.
Getting to Nusa Penida or Lembongan
Fast boats depart from Sanur Harbour for the outlying islands, typically taking 30-45 minutes each way.
Booking ahead during peak season (July-August, December-January) is strongly recommended, since popular morning departures sell out.
