The western third of the island of Java is less visited compared to its busy eastern and central third, despite the national parks, the sweeping beaches, botanical gardens and great surfing available for those passing through. The main draw of this region is Krakatoa, a volcanic island situated between Java and Sumatra. Krakatoa erupted in 1883, producing the loudest sound ever heard in modern history which was heard as far as Perth in Australia. Forty years later a series of eruptions 185m below the surface of the ocean resulted a new island emerging from the volcano’s caldera, called Anak Krakatoa (“Child of Krakatoa”). It is now 195 m high and 2 km in diameter, and is still active. Much of the volcano is now covered in vegetation, making for a fascinating day of scenic hiking.
