Kalimantan is the part of Borneo most travellers want and fewest know how to plan. Flights are limited, distances are huge, and many websites still describe the region as it was ten years ago. In 2026 it is easier than before, with more flights, better roads and cashless payments in most towns. It still rewards travellers who plan their route carefully. This guide shows you how to build a trip around orangutans, rivers, forests and coral, and how much it costs in rupiah.

Kalimantan’s Personality and Why Travellers Go

Kalimantan is Indonesia’s share of Borneo, about 73% of the island. It is slow, wet, green and enormous. Life moves along rivers, not highways. Towns sit on brown water, and the forest begins a short boat ride from the market.

The main reason to come is wild orangutans, but the region offers more. You can watch proboscis monkeys, with their big noses, feeding at dusk in riverside trees. You can swim among stingless jellyfish in the Derawan Islands. You can visit Dayak communities in the interior, and in Banjarmasin you can shop at a floating market at sunrise.

Early morning on a river is the best part. Mist sits on the water, the engine of your wooden boat thumps softly, and a long-tailed macaque watches from a branch. Gibbon calls drift across the forest, and the air smells of wet leaves and wood smoke.

What changed since 2024:

• The new capital, Nusantara (IKN) in East Kalimantan, has brought upgraded roads and more flights. The Balikpapan–Samarinda toll road makes that trip much faster than the old route.
• QRIS cashless payments work in most city shops, cafes and many guesthouses.
• Foreign visitors use the e-Visa on Arrival, about IDR 500,000 for 30 days, and complete the digital arrival form before landing.
• Jungle lodges and boat operators now take online bookings, though many still confirm by WhatsApp.

Best Bases and Regions

Kalimantan has no single centre, so choose your base by what you want to see. Each region below suits a different traveller.

Pangkalan Bun and Kumai (Central Kalimantan)

This is the gateway to Tanjung Puting National Park, the classic orangutan trip. Pangkalan Bun is a quiet town with basic hotels and a small airport. Kumai is the port town where boats depart. It suits first-time visitors and wildlife photographers.

Balikpapan (East Kalimantan)

Balikpapan is the most comfortable city in Kalimantan, with a seafront, malls, good hotels and ride-hailing. It is the best base for Samboja Lestari, Sungai Wain forest and the Mahakam region. It suits families and travellers who want ease before or after the jungle.

Samarinda and the Mahakam River

Samarinda sits on the Mahakam, a long river that leads to Dayak villages and the rare freshwater Mahakam dolphin (pesut). It suits culture seekers who accept slower travel.

Banjarmasin (South Kalimantan)

Banjarmasin is a canal city, sometimes called the “City of a Thousand Rivers.” It is best for floating markets, riverside life and proboscis monkeys at nearby Pulau Kaget. It suits travellers who enjoy local life over big nature trips.

Pontianak (West Kalimantan)

Pontianak sits right on the equator, on the Kapuas River. It has Chinese-Malay-Dayak heritage, famous coffee shops and access to Danau Sentarum, a vast seasonal lake and wetland system.

Berau and the Derawan Islands (East Kalimantan)

For snorkelling and diving, base yourself around Tanjung Batu, Derawan or Maratua. The islands feature green turtles, Kakaban’s jellyfish lake and manta rays near Sangalaki. They suit divers and beach travellers.

Top Wildlife and Rainforest Highlights

Tanjung Puting National Park

This is the headline experience. You travel up the Sekonyer River on a klotok, a two-deck wooden houseboat with a cook, captain and guide. Rangers hold feeding sessions at Tanjung Harapan, Pondok Tanggui and Camp Leakey, where semi-wild orangutans arrive from the forest. You often see wild proboscis monkeys, macaques and hornbills from the deck.

Most trips last two to four days. Two nights gives a good balance. Three nights lets you add a longer walk to Camp Leakey and more time on the river.

Samboja Lestari and Sungai Wain (near Balikpapan)

Samboja Lestari is a rehabilitation and reforestation project that also houses sun bears, the world’s smallest bear species. Sungai Wain Protection Forest has guided jungle walks close to the city. This is the easiest wildlife stop if you have only one or two days.

Kutai National Park

Kutai, reached from Sangatta, has wild orangutans in lowland forest. It is less polished than Tanjung Puting and needs more effort, which some travellers prefer.

Sebangau National Park

Near Palangka Raya, Sebangau protects peat swamp forest and a large wild orangutan population. The water is tea-coloured from peat. It is quieter than Tanjung Puting and ideal for travellers who want fewer boats.

Derawan, Kakaban and Maratua

Swimming in Kakaban lake, with thousands of stingless jellyfish pulsing around you, is unforgettable. Divers should plan time at Sangalaki for manta rays and Maratua for reef walls.

Mahakam Dolphins and Dayak Culture

Boat trips from Samarinda or Muara Muntai can spot pesut, the Irrawaddy dolphin, in the river. Pampang Cultural Village near Samarinda stages Dayak dance performances on Sundays. Visit respectfully and ask before taking photos.

Danau Sentarum

This wetland in West Kalimantan floods each year, and villages sit on stilts above the water. It is remote and takes planning, but it is among the least visited wildlife areas in Borneo.

Where to Eat and Drink

Eating well in Kalimantan means knowing which town does what. Here are specific places to start.

• Banjarmasin: Try soto Banjar at the stalls around Jalan Kuin and the riverfront along Siring Sungai Martapura. At dawn, tea and fried snacks are sold from small boats at the floating markets, including Lok Baintan.
• Balikpapan: The seafood warung along Pantai Melawai and the stalls around Pasar Klandasan serve grilled fish, crab and sambal. Pasar Kebun Sayur is busy in the early morning with produce and snacks.
• Samarinda: Walk the Mahakam riverfront (Tepian) in the evening for grilled corn, meatballs and fried bananas. Pasar Pagi and the Citra Niaga area have lunch food and amplang, crunchy fish crackers made locally.
• Pontianak: Visit the coffee houses around Jalan Gajah Mada in the morning for strong coffee and kaya toast, and look for chai kwe (steamed dumplings) in the markets. At night, riverside stalls grill fish and satay along the Kapuas.
• Kumai and Pangkalan Bun: Warung near the Kumai waterfront serve fresh grilled river and sea fish with rice and sambal. Pangkalan Bun’s night stalls near the town centre sell fried noodles, fried chicken and iced drinks.
• On your klotok: The cook prepares rice, vegetables, fried tempeh, eggs, fish and fruit. Expect simple home-style meals, with coffee and tea available all day.

Getting Around

Flights

Flights are the main way to cover long distances. Jakarta and Surabaya connect to Pangkalan Bun, Balikpapan, Banjarmasin and Pontianak. Smaller airports such as Berau and Palangka Raya connect through bigger hubs. Book early for school holidays. Flight prices in 2026 usually run around IDR 1.2–2.5 million one way between Java and Kalimantan.

Ride-hailing and taxis

Gojek and Grab work well in Balikpapan, Samarinda, Banjarmasin and Pontianak. In Pangkalan Bun and smaller towns, service is patchy, so arrange transfers through your hotel or tour operator. Airport taxis often have fixed prices at counters.

Roads and long-distance buses

The Balikpapan–Samarinda toll road cuts the trip to about 1.5–2 hours. Intercity travel elsewhere still uses regular roads, which can be slow in rain. Overnight buses exist but are tiring. For most travellers, flying is better value for time.

Rivers and boats

Klotoks, speedboats and longboats are the usual transport in wildlife areas. Always wear a life jacket and avoid overloaded boats.

Angkot and local transport

Angkot (shared minivans) operate in larger towns but have limited routes and no fixed schedules. They are cheap but slow, and useful mainly in Banjarmasin and Pontianak. Becak and ojek (motorbike taxis) fill gaps in small towns.

Day Trips from the Main Gateways

• Samboja Lestari from Balikpapan: About 1.5–2 hours by car each way. Allow a full day to see the sun bear centre and orangutan island, with a guided tour if available.
• Sungai Wain from Balikpapan: About 45–60 minutes by car. A half-day guided walk gives you tropical forest without leaving the city region.
• Pulau Kaget from Banjarmasin: About 1–2 hours by road and boat. Go in the late afternoon to see proboscis monkeys settle into the trees.
• Pampang Cultural Village from Samarinda: About 30–45 minutes by car. Sunday performances are the highlight. Plan a half day.
• Lok Baintan Floating Market from Banjarmasin: A short boat ride at sunrise. Leave very early, since the market is mostly finished by mid-morning.

Evenings and Entertainment

Kalimantan is not a nightlife destination in the Bali sense. Evenings are quieter and more local, and that is part of the charm.

• Balikpapan: The most active scene. Cafes, live acoustic music and seafront restaurants cluster around Melawai and the newer lifestyle areas. Hotel bars and a few clubs cater to business and mining crowds.
• Samarinda: Riverside cafes and live music venues appear along the Mahakam. Mostly relaxed rather than rowdy.
• Pontianak: Coffee shops stay open late, with locals playing cards and chatting. Visit the Equator Monument area for casual evening food stalls.
• Banjarmasin: Walk the illuminated riverfront promenade at Siring after dark. Food carts, families and teenagers gather there.
• In the jungle: Your night is the forest itself. After dinner, you can look for fireflies, listen to frogs and watch the stars from the boat deck. Guided night walks may spot tree frogs, stick insects and sometimes slow lorises.

Alcohol is easy to find in Balikpapan hotels and bars but harder in more conservative towns. On klotok trips, bring your own if you want a drink, and discuss it with the crew first.

Shopping

Kalimantan shopping is about crafts and local fabric, not big brands.

• Kampung Sasirangan, Banjarmasin: The home of sasirangan, a hand-dyed fabric with colourful patterns. Buy scarves, shirts and cloth directly from makers.
• Martapura: Known for gemstones and diamond polishing. Prices vary and quality differs, so compare carefully and avoid buying expensive stones without a certificate.
• Dayak beadwork and woven baskets: Look for these at Pampang Cultural Village, Samarinda craft stalls and Pontianak souvenir shops. Real beadwork takes time to make and costs more than factory copies.
• Samarinda Sarong (Sarung Samarinda): A traditional woven cloth sold in Samarinda markets and shops.
• Amplang and dried fish snacks: Good gifts from Samarinda and Balikpapan markets.
• Malls in Balikpapan: Good for essentials, power banks, sunscreen, rain jackets and camera gear before you head into the interior.

Never buy products made from wildlife, such as hornbill casques, animal teeth or skins. They are illegal and harm the species you came to see.

Where to Stay by Budget

Budget

In Pangkalan Bun, Kumai, Banjarmasin and Samarinda, expect simple guesthouses and small hotels with air-conditioning, private bathrooms and basic breakfast. Prices run about IDR 250,000–500,000 per night. For jungle trips, the cheapest klotok cabins are shared, with mattresses, mosquito nets and shared bathrooms.

Mid-range

Three- and four-star hotels in Balikpapan, Pontianak and Samarinda cost about IDR 600,000–1.2 million per night. In Tanjung Puting, mid-range travellers choose a private klotok with better cabins or a small eco-lodge near the park edge, typically IDR 800,000–1.5 million per night.

Luxury

Balikpapan and Samarinda have the best upscale hotels, from about IDR 1.5–3 million per night. Premium jungle options include private boats with extra staff and upgraded bedding, and island resorts in Derawan and Maratua, which can be IDR 2–5 million per night or more.

Best Time to Visit

The dry season, roughly May to September, is the best period for river trips and walks. Trails are firmer, water levels are suitable for boats and mosquitoes are fewer, though the forest is never truly dry. Orangutans also come to feeding platforms more reliably in this period, because wild fruit is scarcer.

From about December to March, heavy rain can disrupt boat schedules and flights. Wild fruit is abundant, so orangutans may stay deep in the forest. Rain also brings fewer tourists and lower prices.

Between August and October, haze from peatland fires can affect air quality, particularly in Central and South Kalimantan. Check air-quality updates before booking non-refundable travel, and carry masks. For Derawan, the best diving and snorkelling conditions are generally March to October, with calmer seas in many months.

Peak times include Indonesian school holidays in June–July and the end-of-year period. Book flights and klotoks early for those dates. Festivals vary by community, so ask local operators about Dayak harvest celebrations and regional cultural events during your trip.

Practical Tips

• Safety: Kalimantan is generally safe for visitors. Main risks are river accidents, heat and insects, not crime. Use life jackets, sunscreen, repellent and travel insurance with medical evacuation cover.
• Health: Talk to a doctor about vaccines, malaria and dengue prevention before travel. Carry a basic first-aid kit with rehydration salts, antihistamines and blister care.
• Orangutan etiquette: Keep at least 10 metres away, never touch or feed them, and do not approach if you are sick, since they can catch human illnesses. Wear a mask if a ranger advises it, and follow the guide’s instructions at all times.
• Tipping: Not required, but appreciated. For klotok crews, many travellers tip about IDR 100,000–200,000 per person for a multi-day trip, shared among the crew and guide.
• Language: Indonesian is widely spoken. English is common at tour operators and hotels in main cities, less so in villages. Learn simple phrases like terima kasih (thank you) and permisi (excuse me).
• SIM cards: Telkomsel has the best coverage in Kalimantan, with XL as a backup. Signal is good in cities and weak or absent deep in the forest. Download offline maps before your trip.
• Water: Drink only bottled or filtered water, and ask your boat operator to provide refills. Bring a reusable bottle to cut down on plastic.
• Money: ATMs are common in cities but scarce on river routes. Carry cash for park entry, tips and small purchases, and use QRIS where accepted.
• Prayer times and midday rest: In Muslim-majority towns, some shops close briefly around midday on Fridays, and prayer calls echo across the water at dawn. Plan errands around these times.
• Dress: Light, long-sleeved clothing protects against sun and insects. Bring a rain jacket, sturdy sandals and a hat.

Frequently Asked Questions

Where is the best place to see orangutans in Kalimantan?

Tanjung Puting National Park is the most reliable. Rangers hold daily feedings at Camp Leakey, Pondok Tanggui and Tanjung Harapan, and wild orangutans are often seen from the klotok boat. Sebangau and Kutai National Parks also offer sightings, but they need more effort and luck.

How many days do I need to explore Kalimantan?

Plan at least five days for a Tanjung Puting trip: one for flights, two or three on the river, and a buffer for delays. For a wider trip combining Balikpapan, Samboja Lestari and Derawan, allow ten to fourteen days because flights are limited and boats depend on weather.

Is Kalimantan safe for tourists?

Yes. Kalimantan has low tourist crime compared with big cities. The main risks are river travel without life jackets, heat, mosquito-borne illness and haze during burning season. Use licensed guides, drink bottled water, carry insect repellent and take travel insurance that covers medical evacuation.

Do I need a guide to visit the rainforest?

For national parks, yes. Tanjung Puting requires a licensed guide and a registered boat, and most operators bundle both. In cities like Balikpapan or Banjarmasin you can go independently, but a guide helps with floating markets and remote Dayak villages where English is rare.

What is the best month to visit Borneo for wildlife?

May to September is the driest and easiest period for river trips and trekking. Wild fruit is scarcer then, so orangutans visit feeding platforms more often. August to October can bring haze from peatland fires, so check air-quality updates before you book flights.
