Anak Krakatau
The smoking child of the volcano that darkened the world, still growing from the sea.
The island isn't old enough to have a history — it's still making one. Anak Krakatau (Child of Krakatoa) rose from the sea in 1927 in the caldera left by its parent's 1883 eruption — the blast that killed 36,000 people, lowered global temperatures, and produced sunsets so vivid they influenced European painting for a decade. The child volcano continues to grow, erupt, and reshape itself. In 2018, a flank collapse triggered a tsunami. Approaching by boat from Java's coast, the island smokes against the sky — still building, still dangerous, still humbling.
Anak Krakatau is an active volcanic island in the Sunda Strait between Java and Sumatra, situated within the caldera of the original Krakatoa volcano. The 1883 eruption of Krakatoa was one of the most catastrophic volcanic events in recorded history, producing pyroclastic flows, a series of tsunamis up to 30 metres high, and ejecting an estimated 25 cubic kilometres of material. The explosion was heard 4,800 kilometres away. Anak Krakatau emerged from the sea in 1927 and has been intermittently active since, growing to approximately 338 metres before a December 2018 flank collapse reduced it significantly and triggered a tsunami affecting western Java and southern Sumatra. The island currently sits at Alert Level 2 (out of 4) with a 2km exclusion zone. When access is permitted, boat tours depart from Carita Beach or Anyer on Java's west coast (4-5 hours by road from Jakarta). The crossing takes approximately 90 minutes.

Friends
Chartering a boat to Anak Krakatau, swimming in the warm volcanic shallows, and camping on a nearby island make a genuinely unique group expedition from Jakarta.
- The 1883 eruption of its parent volcano killed 36,000 people and caused global temperature drops — one of history's most consequential eruptions.
- Anak Krakatau literally means 'Child of Krakatoa' — it emerged from the sea in 1927 and continues growing.
- The 2018 flank collapse triggered a deadly tsunami, making this one of Earth's most actively dangerous volcanoes.
- Standing on the black sand beach of an island that didn't exist a century ago delivers profound geological perspective.
