Biak, Indonesia’s Best WWII Relics, Pristine Diving & Papuan Culture (2026)
While crowds flock to Bali for its beaches, Biak, Indonesia delivers a raw, untamed adventure steeped in pivotal history. This small island off the north coast of Papua was the site of Operation Tabletennis in 1944, a brutal WWII battle that left over 100 Japanese caves and dozens of wrecked aircraft scattered across its jungles and reefs. Today, you can snorkel over a sunken Zero fighter one hour and be the only visitor at a sacred ancient painting site the next, all for a fraction of the cost of mainstream Indonesian tourism.
Why Biak, Indonesia Stands Out

- Historic Architecture: The Japanese Caves of Gua Jepang, a vast network of tunnels and bunkers built in 1943, offer a haunting glimpse into the island’s strategic WWII past.
- Cultural Scene: The vibrant Wor Biak Festival, typically held in July, showcases the powerful singing, dancing, and *wor* (traditional boat) racing of the Biak Numfor people.
- Local Specialties: Don’t miss Papeda, a staple sago porridge eaten with tangy yellow fish soup, using your hands to savor the unique gelatinous texture.
Pro Tip: Visit during the dry season (May to October) for optimal diving and trekking conditions. For the ultimate experience, time your trip for early July to potentially catch the Wor Biak Festival, but confirm exact dates locally as they can vary.

Planning Your Trip: Practical Essentials
Getting There and Around
- By Air: Frans Kaisiepo Airport (BIK) is the main gateway, with daily flights from Jakarta and Jayapura on Garuda Indonesia and Wings Air. A taxi to Bosnik or Kota Biak costs around 150,000 IDR. Book flights at Skyscanner for best deals.
- By Train: No train service exists on Biak Island. For inter-island travel, you must rely on air or infrequent Pelni passenger ships, which are an adventure in themselves. Reserve tickets at Trainline or the national railway website for other parts of Indonesia.
- By Car: Renting a car or motorbike is the best way to explore. The coastal road is decent, but inland routes can be rough. Expect to pay 400,000-600,000 IDR/day for a 4×4 with driver. Compare car rentals at RentalCars.com for options.
- Local Transport: Public transport consists of shared minibuses called *taksi* (not taxis). For specific sites, hiring an *ojek* (motorcycle taxi) or negotiating a day rate with a car and driver is your best bet. A short *ojek* ride starts at 20,000 IDR.
Best Time to Visit
Biak has a tropical rainforest climate, but the dry season offers the most reliable weather for exploration. Savvy visitors know that while it can rain anytime, planning around the seasons makes a huge difference for accessing remote sites and enjoying water activities.
| Season | Weather | Highlights |
|---|---|---|
| Dry Season (May–Oct) | Sunny, less humid, avg 28-32°C, occasional brief showers | Best for diving, trekking, and festival visits; peak visibility underwater. |
| Wet Season (Nov–Apr) | Heavy rainfall, high humidity, avg 26-30°C | Lush greenery, fewer tourists; some roads may be impassable and diving conditions poorer. |
| Shoulder (Apr/Oct) | Transitional, mix of sun and rain | Good balance of decent weather and lower chances of crowds; ideal for flexible travelers. |

Where to Eat: Biak, Indonesia’s Best Bites
Biak’s cuisine is a taste of Papua—simple, fresh, and centered on the sea and sago. You’ll eat incredibly well at humble *warungs* (food stalls) where the catch of the day is grilled over coconut husks. Don’t expect fancy presentation; expect bold, authentic flavors.
Must-Try Local Specialties
- Papeda with Kuah Kuning: The iconic sago porridge, eaten by twirling it around a fork, served with a sour, spicy yellow fish broth. Try it at any local family-run *warung*.
- Ikan Bakar Rica-Rica: Fresh fish (like tuna or snapper) grilled and smothered in a fiery, lemongrass-infused *rica-rica* chili sauce. **Depot Kita** does an excellent version.
- Sate Ulat Sagu: For the adventurous, these are skewers of sago grubs, a protein-rich delicacy often roasted over fire. You might find them at local festivals or markets.

Where to Stay
Accommodation ranges from basic homestays to a few comfortable hotels. Most places are in Kota Biak (the main town) or the diving hub of Bosnik. For a more immersive experience, a homestay in a village can be arranged through local guides. Compare prices and book at Booking.com or Airbnb for apartments.
Best Neighborhoods for Accommodation
- Kota Biak: The administrative center. Best for first-time visitors, with the most hotel options, restaurants, and easy access to the airport and Japanese Caves. Can feel less “tropical island.”
- Bosnik Area: The diving and beach hub. Your best bet if your focus is underwater adventure. You’ll find dive resorts and guesthouses right by the pier, but fewer general amenities.
- Rural/Village Homestays: For cultural immersion. Arranged through local contacts, these offer a unique glimpse into daily life. Be prepared for very basic facilities (often shared bathrooms, no AC).

The Indonesian Rupiah (IDR) is the currency. Carry ample cash—credit cards are only accepted at the airport, the top hotel, and a few dive resorts. ATMs are available in Kota Biak and Bosnik, but they can run out of cash, so withdraw when you see one working.
3. How do I get from the airport to the city center?
Frans Kaisiepo Airport (BIK) is just 4 km from Kota Biak. Your best bet is to take an official airport taxi for a fixed fare of about 150,000 IDR to town. Some hotels offer pickup if arranged in advance. Book airport transfers at GetYourGuide for convenience, though local on-the-spot booking is more common here.

You can manage with basic Indonesian. English is not widely spoken outside the tourism industry (dive shops, main hotels). Learning a few phrases will greatly enhance your interactions and is seen as a sign of respect. A translation app can be very helpful.
5. What’s the appropriate dress code?
Dress modestly and for a humid climate. Light, loose-fitting clothing that covers shoulders and knees is essential for villages
