Chitwan, located at the base of the Himalayas, is one of the few still-untouched parts of the "Terai" region, which once covered the Indian and Nepalese foothills. It is especially abundant in vegetation and fauna.

The first national park in Nepal was created in 1973 and is known as Chitwan National Park (CNP). The property, which is situated in Nepal's Southern Central Terai and once covered the foothills, spans 93,200 hectares and four districts: Chitwan, Nawalparasi, Parsa, and Makwanpur.

The park is a location of great natural beauty due to the breathtaking scenery that is covered in lush flora and the Himalayas in the background. One of the most beautiful and alluring regions in Nepal's lowlands is Chitwan, which is characterised by its forested hills and shifting river landscapes. 

Forests that are tropical and subtropical cover the Chitwan valley. 70 percent of the park is covered in sal woods. Local celebrations and religious offerings use sal leaves as dishes. In the park, there are 20 percent grasslands. There are more than 50 different kinds of grass, including the enormously tall elephant grass (Saccharum spp. It can reach a height of 8 metres.

It is among the most popular tourist destinations of its kind in the area due to its location in a river valley basin, high cliffs on the south-facing slopes, and a mosaic of riverine forest and grasslands along the river banks. The best time to visit is from October through February, when temperatures are on average 25 degree celsius.

With a distinctive collection of indigenous plants and animals from the inner Terai and Siwalik ecosystems, Chitwan National Park is a superb illustration of biological evolution. The land is home to the delicate Siwalik-hill ecosystem, which includes some of its most recent specimens as well as alluvial flood basins.

It is also the habitat for Bengal Tigers & Asiatic rhinos. Exceptionally rich in species diversity, the park is home to 31% of Nepal's mammals, 61% of its bird species, 34% of its amphibians and reptiles, and 65% of its fish species. 

The park is also well-known for having one of the largest bird populations in the world (more than 350 species), is listed among WWF's 200 Global Eco-regions and is recognised as one of the world's biodiversity hotspots by Conservation International. Some of these species are: Bengal florican, Lesser florican, Giant hornbill, Black stork, While stork, etc.
