Why Visit Krakatau?
Few places on Earth carry the geological drama and historical weight of Krakatau. Standing on the slopes of Anak Krakatau — or gazing up at the towering cliffs of Rakata — is to stand at the edge of one of nature's most powerful forces. For travellers who want more than a beach holiday, a day trip or overnight expedition to Krakatau is an unforgettable experience.
That said, this is not a typical tourist destination. Krakatau is an active volcano in a remote marine environment. Careful planning, awareness of current volcanic conditions, and choosing a reputable operator are essential.
Getting There: Your Two Main Departure Points
All visits to Krakatau involve a boat crossing of the Sunda Strait. There are two main departure points:
| Departure Point | Province | Approx. Boat Journey | Notes |
|---|---|---|---|
| Carita / Anyer | Banten, Java | 2–3 hours | Most popular; many tour operators available |
| Kalianda / Bandar Lampung | Lampung, Sumatra | 2–3 hours | Fewer tourists; good alternative option |
Most travellers access Carita or Anyer from Jakarta. The drive from central Jakarta typically takes 3–4 hours depending on traffic. It is worth booking an overnight stay in Carita or Anyer before an early morning departure.
What to Expect on the Trip
A typical day trip from the Java coast includes:
- An early morning boat departure (usually 6–8 AM)
- A crossing of the Sunda Strait — the sea can be choppy, particularly during the wet season
- Time at the islands: depending on volcanic alert levels, this may include a guided walk on Anak Krakatau or observation from a safe distance
- Snorkelling at surrounding reefs (conditions permitting)
- A stop at Rakata for views of the dramatic 1883 cliff face
- Return to the mainland by afternoon or early evening
When Is the Best Time to Go?
The dry season (April to October) generally offers calmer seas and better visibility. The wet season (November to March) can bring rough waters that make the crossing uncomfortable or unsafe. However, volcanic activity does not follow seasonal patterns — always check the current alert status before booking.
Safety Considerations
This cannot be overstated: Krakatau is an active volcano. Before any visit:
- Check the current volcanic alert level issued by PVMBG (Indonesia's Center for Volcanology and Geological Hazard Mitigation). When the level is 3 or 4, access is restricted or prohibited.
- Choose a licensed and experienced tour operator — avoid unlicensed boats.
- Never approach the active crater against guide instructions.
- Wear sturdy footwear, bring a dust mask, and carry sufficient water.
- Be aware of tsunami risk — if the volcano suddenly increases activity while you are on the water or ashore, follow your guide's instructions immediately.
What to Bring
- Sunscreen and a hat (the crossing is exposed)
- Seasickness medication if you are prone to motion sickness
- Sturdy closed-toe shoes for walking on volcanic terrain
- A dust mask or N95 respirator
- Camera or binoculars
- Snorkelling gear (or rent from your operator)
- Cash in Indonesian Rupiah — there are no ATMs on the islands
Respecting the Reserve
The Krakatau islands are a protected nature reserve. Do not remove rocks, coral, or plant material. Stay on marked paths and follow your guide at all times. The ecosystems recovering here are scientifically significant — treat the environment accordingly.
