For most travelers, 10 to 14 days is a good amount of time for Indonesia. Because the country is spread across many islands, that is usually enough to enjoy 2 to 3 regions without spending too much of your trip in transit. Rough Guides specifically notes that 10–14 days can give you a solid introduction to Indonesia if you keep your plan focused. ([Rough Guides][1])
A simple way to think about it is:
- 5 to 7 days if you want to visit just one main area, such as Bali.
- 10 days if you want a first trip covering places like Bali, Java, and Komodo.
- 2 weeks or more if you want a broader trip with a more relaxed pace or more remote islands. Rough Guides has a sample 10-day first-timer itinerary across Bali, Yogyakarta, Mount Bromo, and Komodo, while Audley also features 13-day Indonesia trips for multi-region travel.
So, 10 days is enough for a good first visit to Indonesia, but 2 weeks is better if you want a more complete and less rushed trip.
