Witness the beauty and power of volcanoes while scenic cruising by Krakatau volcano. Krakatau (or Krakatoa) lies in the Sunda Strait, midway between Java and Sumatra. In 1883, Krakatau had a series of massive explosions that caused deadly tsunamis, hot ash to shoot 50 miles into the air, crimson skies for months and the loudest sound ever recorded—so loud the rumble was heard near Mauritius, which is 3,000 miles away. The blood-red sunsets may have inspired well-known paintings, including Edvard Munch’s The Scream. Krakatau had long-lasting global impacts that went on for years. Anak Krakatau (Child of Krakatau) rose from the caldera in 1927. Like parent, like child, Anak is a mighty force with lots of eruptive activity. Sit back, relax and admire its graceful, tree-cloaked slopes and plumes of ash from the decks of our perfectly sized ship.
