Local insight
Indonesia is spread across islands, so plan flights or ferries between regions and avoid tight connections. Bali is easiest for short trips, while Java and Sumatra require longer travel days. Ride-hailing apps are common in cities, but cash is useful in smaller towns. Rain showers can be sudden, so pack a light poncho and waterproof bag for electronics.
