The eastern part of Java houses almost 10% of Indonesia’s volcanoes, as it is dominated by a series of rugged, spectacular volcanic peaks, 4 of them higher than 3,000 masl, with Mt. Bromo and Mt. Semeru being the most iconic ones, and Mount Ijen, which has also risen in popularity. It contains the world’s largest acidic volcanic crater lake, famous for its turquoise color and dazzling blue flame. East Java will present you an out-of-this-world experience for those who seek to combine adventures and panoramic view.
