History

Anak Krakatoa in February 2008

The eruption of Mount Krakatoa in 1883 was one of the most violent volcanic events on record. A huge explosion (150 megatons of TNT) occurred as seawater hit hot magma and turned instantly to steam. The blast was heard over 4,000 km away in Australia and India. The Volcano Explosivity Index (VEI) of the eruption was 6 (colossal). See volcanoes for background.

The whole volcano was destroyed because of the massive explosion. Parts of the volcano fell into the sea and caused a giant tsunami (40 meters). The dust from the eruption reached the stratosphere and affected weather worldwide for several years. More than 35,000 people were killed by the tsunami and eruption. Only about a third of the pre-1883 island survived the blast.

From 1927 to 1930, there were several underwater eruptions on the site of the old Krakatoa volcano. On August 11, 1930, a new volcano and island appeared. This new volcano and island are called 1 Anak Krakatau (Child of Krakatoa).

There was a combination of tsunami and high tides on December 22, 2018, with more than 400 people dead on both sides of the strait, Banten Province and Lampung Province and more than 150 people missing. The tsunami, which hit without prior detection, was caused by a landslide of 64 hectares from the slope of the volcano into the sea, due to heavy rains and tremors.

Get in

You can reach Anak Krakatoa Island using boats from Anyer beach or Carita Beach in West Java, or Lampung in Sumatra.

From Java

The easiest way to get in to Krakatoa is by chartering a boat from the west coast of Java (province of Banten). Tour operators can be found in most of the coastal towns, such as Anyer or Carita. The range of the tour fee will be around Rp750,000-3,000,0000, depending on the number of participants and the number of days. The price will include transport, food, accommodation in a tent, and a guide.

From Sumatra

A cheaper but more time-consuming way to get to Krakatau is through the island of Sumatra (Lampung province). Lampung can be reached from Java via the frequent ferry service from the port of Merak. From the port of Bakauheni in Lampung, a yellow-coloured angkot (public minivan) can take you to Kalianda for about Rp20,000, and from there to the small harbour of Canti by another angkot (about Rp10,000) or by ojek (motorcycle taxi, Rp20,000).

In Canti there is a small port where you can make a deal with a fisherman, either for a day trip to Krakatau, or for a one-way trip to one of the accommodations. One full-day boat rental will cost you about Rp1,500,000. Alternatively, there is a regular boat from Canti to 2 Sebesi island (daily departure 14:00, return trip at 07:30; one way Rp 20,000). Since 2019 there is also a small ferry boat free of cost to increase the number of visitors to Sebesi island to help the population after the tsunami 2018. It starts from Kalianda harbour (Dermaga Bom) on Wednesdays at 13:00, and turns back at 16:00. In Sebesi, you can also charter a fishing boat for a day, cheaper than in Canti, or simply observe Krakatoa from Gubuk Seng from 16 km distance. To get there have a walk on the main road going southwards (around 2 hr, passing three villages) or hire an Ojek (motocycle taxi) in the main village Tenjang. You may also stay overnight on Sebesi island. There are two homestays near the harbour or stay with a family (as for Pak Hayun).

Beware of strong current and large waves during August, September, October, and November.

Fees and permits

To enter the Krakatau area, tourists must obtain a permit from Balai Konservasi Sumber Daya Alam (BKSDA).
