Indonesia is 17,000 islands, though most trips start with one: Bali, with its rice terraces, temple ceremonies, surf breaks and cafe culture. Beyond it wait Java's volcanoes and Borobudur, Komodo's dragons and diving, Lombok's beaches and the untouched east.
The country runs on warmth and improvisation. Ceremonies close roads without notice, scooters carry families of four, and the standard answer to most problems is a smile and a workaround - pack patience along with the sunscreen.
Bali is a mood board that became a country-within-a-country: temples, rice terraces, surf, smoothie bowls and traffic. It is still worth it if you leave the Canggu–Seminyak strip and go to Ubud, the north coast, or another island entirely. Java, Lombok and the Komodo region are where the 'Indonesia' people rave about usually lives.
Smile, take your shoes off, and do not rush ceremonies that close a road. The island runs on offerings, engines and a sense of humor. Bring patience. It is cheaper than another scooter dent.
