Indonesia is the world's largest archipelago, comprising of five main islands and a multitude of smaller archipelagos, with about 17,000 islands strung across the equator.

A rich history of kingdoms, conquests, colonialism, trade and natural disasters has bequeathed it with an exhilarating kaleidoscope of cultures and traditions, people, languages and religions, aspirations and problems, and the dramatic scenery of changing landscapes.

Unfortunately it is this very diversity of ethnic groups and religions that has put a country of such exotic natural resources to the test. Racial divides and fierce religious hostility, government corruption, uprisings, economic negligence and, more recently, terrorist attacks have been frequent blights on the Indonesian fabric of society. But it is also these diverse cultures that have given the country a splendid heritage of traditions and art, and for centuries it has been a magnet, constantly drawing thousands of people to its shores despite its turbulent nature. Its position along the Pacific 'ring of fire' contributes to its uneasiness; the country is prone to frequent earthquakes and volcanic eruptions.

A holiday in Indonesia offers something for everyone. Sumatra has an untouched wilderness and a diversity of wildlife, highland tribes and unique architecture, wonderful resort-lined lakes and quaint hilltop towns. Java features steaming volcanoes, astonishing historical monuments, a sprawling capital city and traditional dance, music and art. The image of paradise is epitomised in Bali, an island of artistic people and elegant temples, stunning scenery, palm groves, beach resorts and diving. Further east, Komodo is the home to the world's largest lizard, the Komodo dragon.

Indonesia is a land of vigorous colour, of tensions and upheaval, but also of festivals and dancing, golden sunsets and friendly white toothy smiles.

Indonesia is hot and humid all year round, but cooler inland than along the coastal regions. The monsoon from December to March brings the heavy rains. The dry season, from April to October, is the best time to visit as some activities and road travel can be difficult during the rainy season.

Bahasa Indonesia is the official language, but many dialects are spoken. English is widely understood in Jakarta and tourist resorts.

Indonesia spans three time zones. GMT +7 (West, including Java and Sumatra), GMT +8 (Central, including Bali, Sulawesi and Lombok), GMT +9 (East, including Irian Jaya).

Rupiah (IDR) is the official currency and is divided into 100 sen. Foreign currency can easily be exchanged at banks, hotels and money changers in major tourist destinations; US dollars is the most accepted currency. Cash often yields a better exchange rate than travellers cheques, which are not always accepted. It is recommended that travellers cheques also be in US dollars. Most major credit cards are accepted at hotels, restaurants and stores catering to the tourist trade. ATMs are available in main centres. Small change is often unavailable so keep small denomination notes and coins for items like bus fares, temple donations and cool drinks.

Passengers to Indonesia of most nationalities can obtain a 30-day visa on arrival, provided that: (i) they arrive at a major Indonesian airport; (ii) their passport contains at least one unused visa page for the visa-on-arrival sticker; (iii) they are holding return/onward tickets, and the necessary travel documentation for their next destination; and (iv) they can show proof of sufficient funds to cover their stay in Indonesia (at least USD 1,000 or a valid credit card). The visa fee is USD 25. One visa extension, of a further 30 days, is possible, via an application made to the Immigration Office. Note that the day of arrival in Indonesia is counted as the first day of stay, and that fines will be levied against tourists who exceed their permitted period of stay. Visitors wishing to travel to the Indonesian province of Irian Jaya must obtain a special permit ("Surat Jalan") after arrival in Indonesia from the Dinas Intel Pam Pol MABAK in Jakarta, or other regional police headquarters in Biak or Jayapura. It normally takes about two days to obtain this permit. Upon arrival in Irian Jaya, visitors must report to the local police office. Note that a yellow fever vaccination certificate is required, if arriving in Indonesia within six days of leaving or transiting through an infected area. NOTE: It is highly recommended that your passport has at least six months validity remaining after your intended date of departure from your travel destination. Immigration officials often apply different rules to those stated by travel agents and official sources.

There are a number of health risks associated with travel to Indonesia and medical advice should be taken at least three weeks before departing. Malaria is a year round risk except in Jakarta, other large cities and the tourist resorts of Java and Bali. The dengue fever mosquito is found throughout Indonesia and visitors should be aware of a significant increase in reported cases of dengue fever throughout all the country's provinces during the rainy season. Outbreaks of chikungunya fever, also from mosquitoes, have occurred regularly in Indonesia in recent years. Visitors to Java and Sumatra are advised to ensure all polio inoculations are up to date before travel. Outbreaks of bird flu have also occurred and many people have died from the disease; Indonesia has the world's highest death toll from the virus. Travellers are not at risk but are advised to avoid close contact with caged, domestic and wild birds, and ensure that all eggs or poultry dishes are thoroughly cooked as a precaution. Outbreaks of Anthrax and leprosy occur. Travellers' diarrhoea is a major risk; visitors should only drink sealed bottled water and avoid dairy products, uncooked meat, salads and unpeeled fruit. Poor sanitation and eating contaminated food can increase the risk of cholera, typhoid and other diseases. The standard of local medical care is poor and very expensive. It is essential that you take out full medical and travel insurance covering all eventualities. A yellow fever certificate is required from those travelling from infected areas.

Following the bombings in Bali in October 2005, there remains a high risk of terrorism directed against foreigners throughout the country and reports indicate that terrorists are planning further attacks on Westerners and western interests and are likely to be carried out at locations frequented by tourists. Extreme caution is advised in public places, including transport terminals, shopping malls and public buildings, and especially in restaurants, hotels and places of entertainment in tourist areas. The security situation remains unsettled in Sulawesi and foreigners are advised to avoid parts of Maluku, particularly Ambon, and Central Sulawesi. Visitors are also advised to be cautious if travelling to Aceh. Religious violence between Christians and Muslims and unstable politics has also made many parts of Indonesia unsafe for travellers; there is continued risk of harassment of Westerners by fundamentalists. Indonesia has a high crime rate and theft and petty crime is common in tourist areas and on public transport. Credit card fraud is on the increase. It is strongly recommended that visitors contact their foreign office for the latest travel advice before travelling to Indonesia. Flooding and landslides occur frequently during the rainy season between December and March. The safety of air travel in Indonesia has come under the spotlight following a series of fatal airline accidents; six of its airlines have failed to meet international safety standards, including the national carrier, Garuda, and in June 2007 the EU announced that all Indonesian airlines have been banned from entering the EU.

Electrical current is 120/230 volts, 50 Hz. A variety of plugs are in use including the European two-pin and UK-style three-pin.

Due to the hot and tropical climate, when conducting business in Indonesia, formal business attire in a light, cool material is the best option. Indonesia is largely Muslim so dress should be conservative, especially for women. Business cards are often exchanged and it is customary to shake hands with a slight bow when greeting and leaving. Some Indonesian names can be long and hard to pronounce and making an effort to get it right when greeting someone will be appreciated. It is best to use formal titles such as Doctor, or 'Bapak' for Mr. and 'Ibu' for Madam. Business hours vary, government offices are usually open from 7am to 3pm and small businesses from 8am or 9am to 4pm or 5pm.

The international access code for Indonesia is +62. The outgoing code is 001 or 007 followed by the relevant country code (e.g. 00144 for the United Kingdom). When using Voice Over Internet Protocol, the outgoing code is 017. It is not necessary to dial the first zero of the area code. City/area codes are in use, e.g. 36 for Bali and 21 for Jakarta. For operator-assisted international calls, phone 101. The local mobile phone operators use GSM networks and have roaming agreements with most international operators. Internet cafes are available in the main towns and resorts.

Travellers to Indonesia over 18 years do not have to pay duty on 50 cigars or 200 cigarettes or 100g tobacco; alcohol up to 1 litre; perfume for personal use; and personal goods to the value of US$250 per passenger or US$1,000 per family. Travellers not entering on a tourist visa will have to pay duties for photo and film cameras unless these have been registered in their passport by Indonesian Customs. Electronic equipment may not be imported to the country. Prohibited items include Chinese medicines and prints, narcotics, firearms and ammunition, pornography, cordless telephones, fresh fruit or goods to be used for commercial gain.
