Overview
Bandung, the West Java capital in the highlands south-east of Jakarta, pairs colonial-era Art Deco architecture with compact, inexpensive museums. The Geology Museum on Jalan Diponegoro — home to the Blora elephant fossil — sits a few minutes from Gedung Sate, while the free Museum of the Asian-African Conference on Jalan Asia Afrika commemorates the 1955 Bandung Conference.
Suggested itinerary
Day 1: Geology Museum (arrive at 9 AM; closed Fridays) → Gedung Sate and the Gasibu area → afternoon on Jalan Asia Afrika for the Museum of the Asian-African Conference and the Art Deco streets of Braga. Day 2: the cooler northern hills around Dago for art spaces and cafés, or a day trip to Tangkuban Perahu volcano to see the geology you learned about at the museum.
Best time to visit
The drier months (roughly May to September) are best, and Bandung's altitude keeps it cooler than Jakarta year-round. Avoid Fridays and public holidays for the Geology Museum, which closes on those days; weekends bring heavy traffic and day-trippers from Jakarta.
