What should I know before visiting Borneo?

Direct answer

Borneo is a vast, biodiverse island shared by three countries (Indonesia, Malaysia, Brunei). Plan regionally because visa rules, infrastructure and attractions differ between Indonesian Kalimantan, Malaysian Sabah & Sarawak, and Brunei.

Visa & entry requirements

• Indonesia (Kalimantan): Many nationalities get visa-free entry or visa on arrival for short stays; check Indonesia’s official immigration site for current rules and fees. Longer stays need advance visas.
• Malaysia (Sabah & Sarawak): Malaysia grants visa-free entry to many countries for various lengths (often 30–90 days). Note Sabah and Sarawak have slightly separate immigration stamps—rules are similar but check before travel.
• Brunei: Visa-exemptions for many nationals (commonly 14–90 days); others must obtain a visa in advance.
• Border crossings: Overland/river crossings between the three jurisdictions require full passport checks and may have limited crossing points—bring passport, onward ticket, and any required visas. Check up-to-date entry requirements and COVID rules before travel.

Best time to visit

• Dry season (best): March to October — more predictable weather, easier jungle treks, clearer seas for diving. Peak tourism: June–August.
• Wet season: November to February — heavy rains, some trails/dirt roads can be impassable, river levels high (can be good for river travel), diving visibility may fall.
• Wildlife notes: Orangutan sightings can be year-round but dry season can make wildlife spotting easier.

Safety tips

• Jungle hazards: Hire licensed guides for trekking; expect leeches, uneven trails, heat, humidity, and insects. Carry water purification, first-aid, and insect repellent with DEET.
• Health: Vaccinations (routine + yellow fever if required, typhoid, hepatitis A/B) and malaria prophylaxis in some regions—consult a travel clinic. Bring anti-diarrheal meds. Tap water is unsafe—drink bottled or filtered water.
• Crime: Petty theft occurs in cities; use hotel safes, avoid displays of wealth, and be cautious at night. Scams at tourist hotspots exist—book through reputable operators.
• Political/security alerts: Check your government travel advisories for regional advisories (some remote border areas may have restrictions).

Local customs & etiquette

• Respectful dress: In more conservative or rural communities and in Brunei, dress modestly (cover shoulders and knees). In cities and resorts, casual wear is fine.
• Religion: Islam, Christianity, and indigenous beliefs are practiced—respect religious sites, remove shoes where required, and ask before photographing people.
• Local interaction: Small gifts and polite phrases (learn a few Malay/Indonesian phrases) are appreciated. Use right hand for giving/receiving.

Currency & money

• Currencies: Indonesian rupiah (IDR) in Kalimantan, Malaysian ringgit (MYR) in Sabah & Sarawak, Brunei dollar (BND) in Brunei (BND is often accepted interchangeably with MYR in parts of Malaysian Borneo).
• ATMs/cards: Major towns/cities have ATMs; remote areas and river villages are cash-only. Carry small-denomination notes for tips, market purchases, and transport.
• Tipping: Not mandatory but appreciated for guides, porters, and boat crews—small cash tips are common.

Transportation

• Flights: Distances are large—internal flights connect major hubs (Kuching, Kota Kinabalu, Sandakan, Balikpapan, Pontianak, Bandar Seri Begawan). Book early for domestic routes.
• Ferries/boats: Essential for coastal and river travel; schedules vary, and journeys can be slow—reserve tickets where possible.
• Road travel: Main roads are fine in cities; expect long drives on two-lane roads and occasional potholes. Domestic bus services exist; private drivers hireable.
• Jungle access: Access to national parks and lodges often requires a boat or small plane plus guided treks—book through reputable operators.

Must-know tips & local insights

• Wildlife ethics: Visit accredited rehabilitation centers and follow park rules. Don’t feed or crowd wildlife—keep distance from orangutans and other animals.
• Choose reputable operators: For orangutan encounters, river safaris, and diving liveaboards, pick licensed, conservation-minded operators to reduce negative impacts.
• Packing essentials: Lightweight quick-dry clothing, good hiking shoes, rain jacket, strong insect repellent, reef-safe sunscreen, power bank, universal adapter, waterproof dry bags.
• Connectivity: Internet can be slow or intermittent outside cities—buy local SIMs (Telkomsel in Indonesia, Maxis/Digi in Malaysia, DST in Brunei) for data coverage.
• Conservation fees & permits: National parks (e.g., Kinabalu Park, Tanjung Puting, Gunung Mulu) often require entrance fees and registered guides; factor costs and permits into planning.
• Accommodation: Options range from luxury lodges and beachfront resorts to homestays and basic guesthouses—book in advance for peak season.
• Food & water safety: Eat at busy, clean stalls or reputable restaurants. Avoid uncooked street salads unless confident about hygiene.

Plan your trip region-by-region, allow extra travel time, and prioritize eco-friendly choices to protect Borneo’s unique ecosystems. Enjoy the wildlife, riverscapes, and cultural diversity—but travel responsibly.
