East Nusa Tenggara is , in many ways different from the rest of Indonesia. It is geographically, ethnically and culturally a border area where the transition from Asia to Australia and Micronesia takes places.

The islands of East NusaTenggara are formed by the protruding peaks of a mountain chain which begins in northern Sumatra, stretching across Java toward the east. But unlike Sumatra, Java and Kalimantan, which are separated from the Asian mainland by shallow seas, the islands of East Nusa Tenggara have apparently always been separated from the Asian landmass by deep sea-beds. The arid landscape of eastern and southeastern Nusa Tenggara is the result of hot and dry winds coming from the Australian continent. In many coastal areas not a drop of rain falls during most of the year. The rainfall varies between 50 mm and 200 mm a year.
Temperatures vary from hot in coastal areas (30 - 35 degree C) to very cool in mountainous areas (about 15 - 17 degree C). The province of East Nusa Tenggara comprises 566 islands. The three main islands are Flores, Sumba, and Timor.

Flores, a long island located between Sumbawa and Timor, is strewn with volcanoes in a mountain chain dividing it into several regions with distinctive languages and traditions, scenic beauty, good beaches, and natural wonders. The name is Portuguese for "flower", as the Portuguese were the first Europeans to colonize East Nusa Tenggara.

Occupying a unique position at the junction of the Australian and Asian submarine ridges, between the two distinct fauna regions marked by the Wallace Line, here is one of the world's most dynamic marine environments with nearly every species of coral and tropical fish represented.

Predominantly Catholic, there are several examples of its Portuguese cultural heritage like the Easter Procession held in Larantuka, and the royal regalia of the former king in Maumere.
Sumba, formerly known as the Sandalwood island, is known for its horses and Sumba cloth. The island is famous for its arts and handicrafts, particularly the textile "ikat" weaving.

Sumba, however, is not for everyone. Neither the food nor accommodation are up to international standards. But if you are willing to make some sacrifices, you can see an authentic, ancient culture with none of the layers of Hinduism or Islam mostly found elsewhere in the country.

The island is roughly oval in shape. The greatest concentration of those who worship spirits (ancestral and those of the land) is found in West Sumba where two-thirds of the population hold on to their traditional belief. It is here where incredible rituals take place, o.a. the "pasola" where hundreds of horsemen fling spears at each other. (The government allows the ritual to take place, but the spears must be blunt).

Although some exist in East Sumba, it is in West Sumba that one can find a greater number of huge megalithic tombs and traditional thatched and peaked huts raised on stilts.

Many traditional activities, all with a part paying homage to the spirits, take place in the months of July through October. These include the building of "adat" houses and burials when sometimes hundreds of pigs, water buffaloes, horses, and dogs are sacrificed. Other ceremonies include the "pajura" or traditional boxing, the festivals for the lunar new year in October and November, and August 17, Independence Day, horse races and ritual dances.

Timor is the principal island in terms of population where the capital of the province, Kupang, is located. Kupang is now being developed to be the gate-way to Nusa Tenggara. There are direct flights from/to Darwin-Australia.

Timor is rich in various cultures, beautiful sceneries, and a wonderful nature.
Made up of dry, rocky land, isolated communities, rolling cattle land, a variety of styles of architecture, Timor is basically something that possesses its own original characteristics.
Unlike some other parts of East Nusa Tenggara, the roads in Timor are generally good and public transportation is relatively well developed.

Tourist facilities are developing and improving in many ways; fair accommodations have been provided for, roads are improving, and tourist spots easier accessible.
