Quick Answer
There is no direct route from Radin Intan II Airport (TKG) to Anak Krakatau volcano. The only feasible journey is a two-stage trip: first by road to a coastal port, then by sea. The most recommended and efficient way for tourists is to book a private taxi from the airport to Kalianda Port (1.5-2 hours, ~IDR 400K-600K), followed by a pre-arranged speedboat tour (1-1.5 hours). Total one-way travel time is 3-4 hours, with total costs ranging from IDR 800,000 for budget shared options to IDR 2,500,000+ for private all-inclusive tours.
Understanding the Journey: Airport to an Active Volcano
Reaching Anak Krakatau ("Child of Krakatoa") is an adventure in logistics. Unlike typical city-to-city travel, your destination is an active volcanic island in the Sunda Strait, with no airport or commercial ferry pier. All journeys from Radin Intan II Airport (TKG) involve a multi-modal transfer:
- Stage 1 (Land): Travel from TKG Airport on Sumatra to a departure port on the coast.
- Stage 2 (Sea): Cross the Sunda Strait by chartered boat or ferry to the volcano's restricted viewing zone.
The closest and most common ports are Kalianda in South Lampung (Sumatra) and Carita Beach in West Java. Your choice affects travel time, cost, and tour availability.
Stage 1: Taxi & Private Transfers from Radin Intan II Airport
Upon landing at TKG, your first task is to reach a port. There is no train or public bus station at the airport. Here are your ground options:
Airport Taxi (Official)
The most straightforward option. Official taxi counters are in the arrivals hall. Prices are fixed for specific destinations. To Kalianda Port, expect to pay IDR 450,000 â 600,000 for the 1.5 to 2-hour journey. Always confirm the price includes tolls and is for the entire car, not per person.
Pre-Booked Private Transfer (Recommended)
For peace of mind, especially after a long flight, booking a private car in advance via platforms like Klook or with your tour operator is ideal. Benefits include:
- Driver meeting you with a name sign.
- Fixed, agreed-upon price (similar to airport taxi rates).
- Possibility of direct coordination with your boat tour for timing.
- Option for larger vehicles for groups or extra luggage.
Ride-Hailing Apps (Grab/Gojek)
Availability is inconsistent at TKG for long-distance trips to Kalianda. You might find a driver, but they may refuse the long return trip or negotiate a high fixed fee (often matching taxi rates). Not reliable for critical connections.
Public Minibus (Angkot) â For the Adventurous Budget Traveler
Walk outside the airport to the main road to catch a light-blue angkot to Rajabasa Bus Terminal in Bandar Lampung (~IDR 15,000, 30-45 mins). From there, find a bus to Kalianda (~IDR 25,000-40,000, 1.5 hours). This is time-consuming, confusing without Bahasa skills, and not recommended if you have a boat to catch.
Stage 2: Ferry & Boat Crossings to Anak Krakatau
This is the core of the experience. You cannot simply buy a public ferry ticket to the volcano. Access is controlled via licensed tour operators due to safety and conservation regulations (PVMBG).
Departure Ports: Kalianda vs. Carita
| Port | Location (Island) | Travel Time from TKG | Boat Time to Viewing Zone | Key Advantage |
|---|---|---|---|---|
| Kalianda (Canti) | South Lampung, Sumatra | ~1.5-2 hours | ~1-1.5 hours | Closest to TKG Airport, shorter overall travel if coming from Sumatra. |
| Carita Beach | West Java, Java | ~2.5-3.5+ hours (inc. ferry crossing to Java) | ~1 hour | More established tourist infrastructure, wider choice of operators and accommodations. |
Boat Types & Tours
- Private Speedboat Charter: Most flexible and common for small groups (6-10 pax). Costs IDR 2,500,000 â 5,000,000+ for the boat, includes guide, permits, and sometimes snorkeling gear. You set the schedule.
- Shared/JOIN Boat Tour: A cost-effective option where you join a group. Prices range IDR 300,000 â 800,000 per person. Departs on a fixed schedule (usually morning). Bookable through hotels or local agents in Carita/Kalianda.
- Wooden Fisherman Boat (Jukung): A slower, cheaper, and less comfortable option. Only recommended for calm seas and very tight budgets. Safety equipment is a must-check.
Note: According to Indonesia Travel, all boats must stay at a safe distance (often 1-2 km) from the active crater as per current regulations.
The Integrated Solution: Combined Taxi + Boat Tours
Most travelers opt for a seamless package from a single operator. These solve the coordination problem between Stage 1 and Stage 2.
What's Typically Included:
- Private airport pickup at TKG.
- Direct transfer to the port (Kalianda or Carita).
- Boat charter with captain, guide, life jackets.
- All necessary permits and entrance fees to the sanctuary zone.
- Sometimes lunch, snorkeling, or a stop at nearby islands like Sebesi.

Budget Alternative: Public Transport & Shared Boats
For solo backpackers or those with maximum time flexibility, a DIY public transport route exists. This is not time-efficient and requires patience.
The Step-by-Step Breakdown:
- TKG to Bandar Lampung: Take angkot to Rajabasa Terminal (~IDR 15K).
- Bandar Lampung to Kalianda: Public bus (~IDR 30K, 1.5 hrs).
- Kalianda Town to Canti Port: Ojek (motorcycle taxi) or another angkot (~IDR 20K).
- Find a Boat: At the port, ask for "travel Krakatau" or look for shared tour signs. You may need to wait for a group to form. Shared boat cost: ~IDR 300K-500K.
Total One-Way Time: 5-7 hours. Total One-Way Cost: ~IDR 365,000 - 565,000.
Major Drawbacks: Unreliable connections, no permit guarantees, long waiting times, and risk of missing a boat back if on a day trip.
Trip Planning Essentials: Permits, Safety & Best Time
Mandatory Permits & Guides
You cannot visit independently. A licensed guide/operator must obtain the permit from the Krakatau Sanctuary Office and the volcanology agency (PVMBG). This is included in all legitimate tour packages. Always verify this with your operator.
Safety Considerations
- Volcanic Activity: Follow all instructions from your guide. The exclusion zone can change daily based on seismic activity.
- Sea Conditions: The Sunda Strait can be rough. Boats may cancel in bad weather. Sea sickness pills are recommended.
- Boat Safety: Ensure the boat has enough life jackets for all passengers, a working radio/GPS, and is not overloaded.
Best Time to Visit
Dry Season (April - October): Offers the calmest seas and clearest skies, maximizing visibility and comfort. Weekdays are less crowded than weekends. Depart early morning (7-8 AM) for the smoothest water.
Traveler Tips & Insider Recommendations
Beyond logistics, hereâs how to make your Krakatau trip exceptional:
- Accommodation Strategy: Stay overnight in Carita (Java) or Kalianda (Sumatra) before your tour. This allows for an early start and a buffer for flight delays. Carita offers more beachfront resorts.
- Extend the Experience: Many boat tours combine Anak Krakatau viewing with snorkeling at the surrounding reefs (part of the Krakatau Nature Reserve), or a visit to the settled island of Sebesi.
- Pack Smart: Essentials include polarized sunglasses (to see through water glare), a wide-brimmed hat, reef-safe sunscreen, a dry bag, and a power bank. Footwear for a potentially wet boat landing is key.
- Photography Tip: Bring a telephoto lens (200mm+) for detailed volcano shots from the safe distance. A drone requires special permits; check with your operator.
- Manage Expectations: You are visiting an active, evolving natural phenomenon. Cloud cover or increased activity may obscure views. The journey and the raw power of nature are the main attractions.
FAQs: Radin Intan II to Anak Krakatau Travel
Is there a direct bus or train from Radin Intan II Airport to Anak Krakatau?
No, there are no direct buses, trains, or flights to Anak Krakatau itself, as it is an active volcanic island in the Sunda Strait. All journeys involve a multi-stage trip: first from the airport to a coastal port (like Kalianda or Carita), and then a ferry or chartered boat to the volcano viewing area.
What is the cheapest way to get from TKG airport to see Krakatau?
The most budget-friendly method is to take a local minibus (angkot) from the airport to Bandar Lampung city, then a public bus to Kalianda Port (approx. 3-4 hours total, costing ~IDR 80,000-120,000). From there, join a shared public ferry or speedboat to the Krakatau viewing zone (from ~IDR 300,000 per person). This requires significant time and planning.
What is the fastest and most recommended way for tourists?
The most efficient and recommended option for most tourists is to pre-book a private taxi directly from Radin Intan II Airport to Kalianda Port (~1.5-2 hours, IDR 400,000-600,000), then connect with a pre-arranged private speedboat tour to Anak Krakatau (~1-1.5 hours each way). Many tour operators offer all-inclusive packages covering both transport and guide.
Can I visit Anak Krakatau on a day trip from the airport?
Yes, but it requires a very early start. If you land on a morning flight (before 8 AM), you can take a pre-booked taxi to Carita Beach (2.5-3 hours), where many day tour boats depart. A typical day tour returns by evening. It's a long day, and flight delays can disrupt plans, so an overnight stay in Carita or Kalianda is often advised.
Do I need a special permit or guide to visit Anak Krakatau?
Yes. Access to the Krakatau Sanctuary Zone is regulated. You must visit with a licensed tour operator who will obtain the necessary permits from the Volcanology and Geological Disaster Mitigation Center (PVMBG) and the local authorities. Independent visits are not allowed for safety reasons.
Is it safe to visit Anak Krakatau after the 2018 eruption?
Post-2018, the summit area is strictly off-limits due to high volcanic activity. However, licensed boat tours are permitted to approach a safe designated distance for viewing (usually within 1-2 km). Safety is paramount; always choose a reputable operator who monitors official activity alerts and has safety protocols.
What should I pack for the trip to Krakatau?
Essentials include: sturdy shoes (for possible ash/sand), sun protection (hat, sunscreen, sunglasses), motion sickness medication (for the boat), waterproof bags for electronics, plenty of water, snacks, and a light jacket. A camera with a zoom lens is recommended for optimal volcano viewing from the boat.
Where is the best place to stay before a Krakatau tour?
Kalianda (closest to the airport) or Carita Beach (more tourist infrastructure) are the main bases. Carita has more hotel and resort options and is the primary departure point for tours from the Java side. Staying overnight ensures you catch the early morning boat departures, which offer calmer seas and better views.
