Jakarta is one of Indonesia's designated tourist areas. It is a gateway to other tourist destinations in Indonesia and is equipped with all the means of modern transportation by air, sea, rail, or by land. It has the largest and most modern airport in the country, the most important harbor in Indonesia and is well connected by rail of good roads to other destinations in Java, Sumatra, and Bali. As Indonesia's main gateway, Soekarno-Hatta International Airport serves a growing number of international airlines and domestic flights. Jakarta is a city of contrasts; the traditional and the modern, the rich and the poor, the sacral and the worldly, often stand side by side in this bustling metropolis.
