Anak Krakatau, Indonesia

This volcanic island in Indonesia’s Sunda Strait formed after its namesake volcano had one of the deadliest eruptions in history. The immense ash clouds and the powerful tsunamis created by the historic explosion of Krakatau in 1883 killed around 36,000 people. The strength of the eruption meant the original volcano largely collapsed, but some decades later, a new one was born from the crater. It’s known as Anak Krakatau or 'Child of Krakatau'.

Boat tours take people to visit the awe-inspiring active volcano, with groups sometimes camping right on the black sand beach of the volcanic island – depending on activity – or neighbouring isles. A deadly tsunami in Indonesia in December 2018 was triggered by part of Anak Krakatau sliding into the ocean after it erupted under water. Further eruptions were reported in 2023.
