Krakatoa (Krakatau)
Krakatoa, located in the Sunda Strait between Java and Sumatra, is renowned for its cataclysmic 1883 eruption—the deadliest volcanic event in recorded history, which significantly altered global climate and geography.

Mount Ijen
Located in East Java, Mount Ijen is famed for its surreal turquoise crater lake—the world’s largest acidic lake—and its mesmerizing blue flames caused by ignited sulphuric gases.

Mount Kelimutu
Nestled on Flores island, Mount Kelimutu is famous for its trio of volcanic crater lakes, each uniquely colored by mineral content and changing unpredictably from turquoise and green to deep red and black.
