The most populated island of Indonesia is famous for its beautiful volcanic scenery and eight UNESCO world heritage sites. The dry season that spans from May to September is the best time to visit Java. It's the prime time to hike up the volcanoes like Mount Bromo, Mount Semeru, Kawah Putih, and Dieng Plateau. Visitors can even see coffee and cocoa harvests. November is also a good month to explore Java and to go birdwatching or surf in West Java. Rice paddies are especially green and beautiful during or right after the rainy season.
