A 19th-century industrial complex in West Sumatra built by Dutch colonists to extract and export coal. Its mines, company town, and the railway and port that carried the coal to the coast survive as a record of colonial-era mining technology.

Travel Guide
Entry requirements depend on your passport. Check your specific requirements on the Indonesia page at Yoogo.
Indonesia uses the Indonesian rupiah (IDR). Cash is preferred for most everyday transactions, especially outside major cities. ATMs are widely available in urban areas and popular tourist destinations such as Bali and Yogyakarta. Credit cards are accepted at hotels and upscale establishments. Use authorised currency exchange counters or ATMs for the best rates and avoid unlicensed money changers.
Indonesia is generally safe for tourists, though petty theft and scams occur in busy tourist areas. Avoid displaying valuables openly. Some regions, including parts of Papua and areas with historical civil unrest, require extra caution. Indonesia is an archipelago with active volcanoes and occasional natural hazards; check advisories before travel to affected areas. During Ramadan, be mindful that eating, drinking, and smoking in public during daylight hours can cause offence.
Indonesia's size means domestic flights are often the most practical option for inter-island travel, with budget carriers offering affordable fares. On Java, a reasonable rail network connects major cities including Jakarta, Bandung, Yogyakarta, and Surabaya. Within cities, ride-hailing apps Grab and Gojek are convenient and reliable. Taxis are metered in major cities; always insist on the meter. Motorbikes are widely available for hire but require a valid licence and caution on busy roads.
The dry season, roughly April through October, is the best time to visit most of Indonesia, including Bali and Java. The wet season from November through March brings heavy rainfall and occasional flooding. Temperatures remain consistently warm year-round, typically 26–32°C. Bali's high season coincides with the dry months, so accommodation books up quickly. Different islands have slightly varied wet and dry season timing.
Bahasa Indonesia is the official national language and is widely understood across the archipelago's diverse ethnic groups. English proficiency is reasonable in tourist hubs such as Bali and Jakarta's business districts, but limited in smaller towns and rural areas. Learning a handful of basic Indonesian phrases is both practical and appreciated. Many Indonesians also speak their regional ethnic language alongside Indonesian.
No vaccinations are legally required for most travellers entering Indonesia. Travel health professionals commonly recommend hepatitis A, typhoid, and routine vaccinations. Dengue fever is present throughout the country; use insect repellent and appropriate clothing, particularly around dawn and dusk. Bottled water is widely available and recommended over tap water. Consult a travel health clinic at least 4–6 weeks before your trip.
Tipping is not customary in Indonesia but is appreciated in tourist settings. Many restaurants in tourist areas add a service charge to the bill; check before adding your own. For good service at restaurants without a service charge, rounding up or leaving 5–10% is generous. Hotel porters and tour guides appreciate small gratuities. Taxi and ride-hailing fares do not typically include tips.
Indonesia has several competing mobile networks including Telkomsel, Indosat, and XL Axiata. Tourist SIM cards are readily available at airports, convenience stores, and phone shops. 4G coverage is strong in cities and popular tourist areas on Java and Bali; coverage is patchier in more remote islands. Buying a local SIM on arrival is the most cost-effective option for data. Registration is required by law, so bring your passport.
Indonesia is predominantly Muslim; dress conservatively outside beach and tourist areas, covering shoulders and knees. Always remove shoes when entering mosques and many private homes. Showing the soles of your feet or using your left hand to pass items is considered impolite. Avoid public confrontation; maintaining harmony and avoiding causing embarrassment to others is highly valued. Always ask before photographing people. During Ramadan, eating and drinking in public during fasting hours is disrespectful.
