Overview
Kalimantan is the Indonesian portion of Borneo, the world's third-largest island, shared with Malaysia's states of Sabah and Sarawak and the sovereign nation of Brunei. It covers roughly three-quarters of the island and is divided into five Indonesian provinces: West, Central, South, East, and North Kalimantan.
The region is defined by some of Southeast Asia's most significant remaining lowland rainforest, a network of vast rivers including the Kapuas, Mahakam, and Barito, and extraordinary biodiversity that includes orangutans, proboscis monkeys, pygmy elephants, and Irrawaddy dolphins. It is also the ancestral homeland of dozens of Dayak ethnic groups, each with distinct traditions, longhouse architecture, and craft heritage.
Kalimantan is not a polished package-tourism destination. Infrastructure outside provincial capitals and a handful of ecotourism hubs is limited, and travel often involves river journeys, unpaved roads, and flexible planning. That same rawness is precisely what draws independent travelers, wildlife researchers, and anyone seeking experiences genuinely off the mainstream circuit.
Note: The premise of 'Kalimantan, Thailand' in the original request appears to be a geographical error. Kalimantan is an Indonesian territory and has no administrative connection to Thailand. This guide covers Kalimantan, Indonesia accurately.
Before You Go
Visas
Indonesia operates a visa-on-arrival arrangement for many nationalities at designated entry points, but entry conditions, fees, and eligible nationalities change. Do not rely on informal sources. Check TravelerPulse's Visas section and confirm current requirements directly with the Directorate General of Immigration Indonesia (imigrasi.go.id) before you travel.
Health
Consult a travel medicine clinic at least four to six weeks before departure. Malaria prophylaxis is recommended for travel to rural and forested areas of Kalimantan — confirm the appropriate medication with your doctor. Dengue fever is present island-wide; mosquito precautions are essential. Hepatitis A and B, typhoid, and rabies vaccinations are commonly advised. Carry a well-stocked first-aid kit, as medical facilities outside Balikpapan, Banjarmasin, and Pontianak are limited.
What to Pack
- Lightweight, quick-dry clothing that covers arms and legs (insect protection and cultural respect)
- High-SPF sunscreen and strong insect repellent (DEET-based)
- Waterproof dry bags for river journeys
- Sturdy, waterproof footwear
- Portable water purification (tablets or filter)
- Cash in small denominations — ATM access is unreliable outside cities
Connectivity
Local SIM cards from providers such as Telkomsel offer the best rural coverage, though signal drops to zero in deep forest. Download offline maps and any necessary documents before leaving urban areas.
Getting There
By Air
The main international and domestic gateways into Kalimantan are Sultan Aji Muhammad Sulaiman Sepinggan International Airport in Balikpapan (East Kalimantan) and Supadio International Airport in Pontianak (West Kalimantan). Banjarmasin's Syamsudin Noor Airport serves South Kalimantan. Domestic connections from Jakarta, Surabaya, Makassar, and other Indonesian cities are frequent. Direct international connections are limited; most travelers route through Jakarta or Kuala Lumpur.
By Sea
Pelni, the national passenger shipping company, operates inter-island ferries connecting Kalimantan ports with Java, Sulawesi, and other islands. Journeys are long — Surabaya to Banjarmasin, for example, takes around 16–20 hours — but can be an affordable and atmospheric option. Verify current schedules and routes at pelni.co.id.
Overland from Malaysian Borneo
Several official border crossings exist between West and North Kalimantan and Malaysia's Sarawak and Sabah. The Entikong–Tebedu crossing between Pontianak and Kuching is the most established for independent travelers. Verify current border status and entry requirements before planning a cross-border overland journey, as conditions can change.
Getting Around
Rivers as Roads
In much of Kalimantan, rivers are the primary transport arteries. Longboats, klotoks (covered river boats), and express speedboats connect villages and ecotourism areas that roads do not reach. The Kapuas River in West Kalimantan and the Mahakam River in East Kalimantan are particularly central to regional travel. Journey times can be long and conditions basic — bring provisions, sun protection, and patience.
Road Transport
Paved roads connect major towns in South and East Kalimantan reasonably well. Public minibuses (angkot) and shared taxis (travel) operate between larger settlements. In West and Central Kalimantan, road quality degrades significantly outside cities. Renting a motorcycle is common and practical for independently minded travelers, but roads can flood and become extremely slippery during and after rain.
Domestic Flights
For covering large distances quickly, short domestic hops are worth considering. Wings Air and other regional carriers serve smaller airports such as Sampit, Palangka Raya, and Tarakan, though schedules and availability vary. Verify directly with airlines.
Guided River Expeditions
For Tanjung Puting National Park (Central Kalimantan) and the Mahakam River area, booking a multi-day klotok expedition through a locally licensed operator is the standard and recommended approach. Local guides provide crucial navigation, wildlife-spotting expertise, and logistical support.
Things to See & Do
Wildlife and National Parks
Tanjung Puting National Park in Central Kalimantan is Kalimantan's most visited wildlife destination, home to one of the largest concentrations of wild and semi-wild orangutans in the world. The Orangutan Care Center and Quarantine (OCCQ) at Pasir Panjang and the feeding stations at Camp Leakey, Pondok Tanggui, and Tanjung Harapan offer structured wildlife observation. Entry and guide fees apply; verify current arrangements with the park authority or a licensed tour operator.
The Wehea Forest in East Kalimantan is a community-managed protected area with excellent biodiversity and emerging ecotourism infrastructure. Kutai National Park, also in East Kalimantan, harbors orangutans, sun bears, and clouded leopards, though it has suffered significant deforestation pressure — verify current access conditions before visiting.
Dayak Cultural Experiences
Meeting Dayak communities in an ethical, community-consented manner is one of Kalimantan's most meaningful travel experiences. Longhouse visits, traditional craft demonstrations, and cultural festivals can be arranged through reputable local operators, particularly along the Mahakam River in East Kalimantan and in interior West Kalimantan. Avoid any tours that treat communities as spectacles without genuine community benefit.
Rivers and Wilderness
- Kayaking or boating sections of the Kapuas River, Indonesia's longest river
- Trekking in Betung Kerihun National Park (West Kalimantan), a UNESCO-listed transboundary park shared with Sarawak
- Dolphin-watching for Irrawaddy dolphins in the Mahakam Lakes area
Urban Highlights
Balikpapan is a relatively prosperous, modern city with good infrastructure — a practical base. Banjarmasin is known as the 'City of a Thousand Rivers' and its floating markets (most active very early morning) offer a genuine local commerce experience, not merely a tourist set piece. Pontianak sits almost exactly on the equator; the Tugu Khatulistiwa (Equator Monument) marks the line.
Food & Drink
What to Eat
Kalimantan's cuisine reflects its diverse ethnic communities. South Kalimantan (Banjar cuisine) is arguably the most distinctive, featuring soto Banjar (a fragrant chicken soup with glass noodles and spices), nasi kuning (turmeric rice typically served at celebrations), itik Gambut (roasted duck), and various freshwater fish preparations. Sayur asam, a tamarind-based vegetable soup, is found across the island.
In interior regions, Dayak-influenced food includes sago-based dishes, river fish cooked in bamboo, jungle fern vegetables, and wild boar in non-Muslim communities. Coastal areas offer abundant seafood.
Where to Eat
In cities, warungs (small local eateries) and rumah makan (restaurants) provide inexpensive, filling meals. Banjarmasin's floating food vendors on the river are a characterful option for breakfast. Street food stalls in evening markets (pasar malam) are a good way to try local specialties at low cost.
Drinks
Fresh coconut water, various fruit juices, and sweetened iced teas are widely available. Tap water is not safe to drink; stick to sealed bottled water or purified water. Coffee culture is strong — local kopi is typically very sweet and strong, served with grounds settled at the bottom of the glass.
Practical Information
Money
The Indonesian Rupiah (IDR) is the only currency accepted. ATMs are reliable in Balikpapan, Banjarmasin, and Pontianak but scarce in smaller towns and essentially absent in rural areas. Carry sufficient cash before leaving any city. Credit cards are accepted at upscale hotels and some restaurants in major cities only.
Emergency Contacts
Indonesia's national emergency numbers are 110 (police), 113 (fire), and 119 (ambulance/medical). Mobile coverage is unreliable in remote areas — satellite communication devices are worth considering for extended wilderness expeditions. Verify locally whether these numbers function in your specific area.
Electricity
Indonesia uses 220V/50Hz with Type C and Type F (two-pin round) sockets. Bring a universal adapter.
Responsible Travel
- Do not touch, feed, or attempt to handle wild animals, including orangutans — physical contact risks disease transmission for both parties
- Purchase crafts directly from artisan communities or cooperative shops where possible
- Ask permission before photographing people
- Use reef-safe or biodegradable toiletries near waterways
- Choose tour operators who demonstrably employ local guides and contribute to community or conservation funds
Safety
Kalimantan is generally safe for travelers who exercise standard precautions. Petty theft occurs in cities as in any urban environment — keep valuables secured and be alert in crowded markets and transport hubs.
The primary risks in Kalimantan are environmental. River travel carries inherent hazards: currents can be swift, and boats can be overloaded. Jungle trekking without a guide in unfamiliar terrain is inadvisable — disorientation, difficult terrain, and wildlife (including venomous snakes) are real concerns. Always engage licensed, experienced local guides for wilderness activities.
Flash flooding and landslides can affect roads and river levels during heavy rain, which can occur any month but is more frequent October through April. Monitor local weather and be prepared to delay or modify travel plans.
Healthcare infrastructure outside the three main cities is very limited. Evacuation to Balikpapan, Pontianak, or Banjarmasin — or potentially to Singapore — may be necessary for serious medical emergencies. Comprehensive travel insurance that explicitly covers medical evacuation is strongly recommended.
Local Culture & Etiquette
Kalimantan is home to a remarkable diversity of ethnic groups. The Dayak peoples — a broad term encompassing dozens of distinct groups including the Iban, Kenyah, Kayan, Ngaju, and Punan — are the indigenous inhabitants of Borneo's interior and have maintained rich traditions in weaving, woodcarving, beadwork, and music. Many communities observe both traditional animist practices and Christianity or Islam.
Banjar Malay culture is dominant in South Kalimantan and brings strong Islamic traditions to daily life, including prayer times, dress norms, and food practices. In cities and towns across Kalimantan, a significant Chinese Indonesian community maintains its own cultural and religious traditions, visible in clan temples and festivals.
Etiquette
- Dress modestly, particularly when visiting mosques (women should cover hair and both genders should cover knees and shoulders) or attending traditional ceremonies
- Remove shoes before entering homes and places of worship
- Use your right hand for giving, receiving, and eating
- Public displays of affection are considered inappropriate in most contexts
- Ask before photographing individuals, sacred objects, or ceremonies
- If invited to eat or drink, it is courteous to accept even symbolically
