Krakatoa

Krakatoa is a volcanic island group in the Sunda Strait between Java and Sumatra, administratively part of Rajabasa, South Lampung Regency, Lampung Province. It is famous for the catastrophic 1883 eruption and the subsequent emergence of Anak Krakatau (Child of Krakatoa) in 1927. The archipelago is a protected nature reserve within the Ujung Kulon National Park World Heritage site and is visited by boat for volcano viewing and nature observation.

Visitors reach Krakatoa by chartered boat from ports in Banten (Carita, Anyer) or Lampung (Canti, Kalianda). The experience is centered on boat-based sightseeing around the islands, viewing the active cone of Anak Krakatau from a safe distance, observing black sand beaches, lava formations and surrounding waters. Landings are weather and activity dependent and limited to designated zones with a guide. There are no permanent tourist structures on the islands themselves.

Krakatoa is globally known for the eruption of 26-27 August 1883, one of the most powerful volcanic eruptions in recorded history, which destroyed most of the original island and caused widespread tsunamis. The caldera collapse left remnants Rakata, Sertung and Panjang. In 1927 a new island, Anak Krakatau, emerged from the caldera and has since grown through ongoing volcanic activity, remaining one of Indonesia's most active volcanoes.
