The Terai region is composed of a 26 to 32 km wide broad belt of alluvial and fertile plain in the southern part of the country. This belt extends from the westernmost part of the country to the eastern limit and covers about 17% of the total land area.

In between the Chure hills, rising abruptly to the north of the southern plains and the Mahabharat range, are a number of low valleys called "Duns". The Duns resemble the Terai in relief and climate and are also called the Inner Terai. The Chure range running east west across the country is shaped like a hedge. The hills of this range are rather sparsely forested, averaging 600 to 1220 meters in altitude and 8-16 km in breadth. The soil is immature and dry.

Chitwan

Chitwan is one of the finest national Parks in Asia, renowned for its dense concentration of wildlife and top class tourist lodges, which provides the opportunity to see animals in their natural habitat.

Chitwan which means the heart of the jungle is among the last surviving examples of the continuous band of forests and grasslands which once extended from the Indus River in Pakistan to the Burmese border.

The main attraction here is the Royal Chitwan National Park, one of the largest forest regions in Asia teeming with wildlife such as the rare great one-horned rhinoceros, several species of deer, sloth bear, leopard, wild boar, fresh water dolphin, crocodile, more than 350 species of birds and the elusive Royal Bengal Tiger.

Royal Chitwan National Park is listed in the UNESCO World Heritage Site (natural) list.

Janakpur

It is a great religious and historical place. Janakpur is famous as the birthplace of Sita, the consort of Lord Rama. There is an artistic marble temple of Sita (Janaki), popularly known as Naulkha Mandir. Religious festivals, trade fairs and other festivities are held here on Bivaha Panchami and Ram Navami. Janakpur is also linked with Kathmandu by air and road. It is a part of Central Nepal.

Lumbini

Lumbini, the birthplace of Siddhartha Gautama, the Shakya prince and the ultimate Buddha, the Enlightened One, is the pilgrimage destination of the world's millions of people faithful to all schools of Buddhism. This nativity site, identified by Indian Emperor Ashoka's commemorative pillar is listed as a World Heritage Site by UNESCO.

The main attraction at the Lumbini remains the Sacred Garden spread over 8sq km and possessing all the treasures of the histroric area. The Mayadevi temple is the main attraction for pilgrims and archaeologists alike. Here we find a bas relief of Mayadevi, the Buddha's mother giving birth to him. Standing west to the Mayadevi shrine is the oldest monument of Nepal, the Ashokan Pillar. The pillar was erected by Emperor Ashoka in 249BC to commemorate his pilgrimage to the sacred site. To the south of the pillar, we find the sacred pond, Puskarni, where queen Mayadevi had taken a bath just before giving birth to the Buddha.
