The Terai Lowlands of Nepal
Nepal's hot southern plains hold its richest farmland, famous jungle parks and Lumbini — here's the Terai's geography, climate and highlights.
The Terai is Nepal's southern doorstep — a flat, fertile ribbon of plain that could not feel more different from the snowy peaks the country is famous for. It is hot, green and densely farmed, and it holds some of Asia's greatest wildlife.
The short answer
The Terai is the low southern plain of Nepal, lying mostly below 300 metres along the Indian border. It has a subtropical climate — hot summers, a heavy monsoon and mild winters — and is home to Nepal's richest farmland, its biggest jungle parks like Chitwan, and the Buddha's birthplace at Lumbini. Visit between October and March for the most comfortable weather.
Geography and climate
The Terai forms the northern edge of the great Indo-Gangetic plain. It is broken in places by the low Chure (Siwalik) hills and pockets of inner valleys called the inner Terai, where Chitwan sits. The land is laced with rivers draining from the Himalaya, which deposit the silt that makes the soil so fertile.
The climate is the hottest in Nepal:
- Spring (Mar–May): Increasingly hot and dusty, peaking near 40C before the rains.
- Monsoon (Jun–Sep): Heavy rain, lush growth and risk of flooding.
- Autumn (Oct–Nov): Warm days, clearing skies, the start of safari season.
- Winter (Dec–Feb): Mild, dry and the most comfortable time to visit.
Wildlife and parks
The Terai is Nepal's safari country. Chitwan National Park is the most accessible, famous for the greater one-horned rhinoceros, while Bardia National Park in the far west offers the best chance of a wild Bengal tiger. Other lowland reserves include Parsa, Banke, Shuklaphanta and the great birding wetland of Koshi Tappu. Safaris run by jeep, on foot and by dugout canoe.
People and culture
The Terai is the heartland of the Tharu, an Indigenous people long adapted to the malarial jungle, alongside Madhesi communities with close cultural ties to northern India. The region is also home to Lumbini, the birthplace of Siddhartha Gautama, the Buddha, and one of the most important pilgrimage sites in the Buddhist world.
Farming and the economy
The Terai is Nepal's breadbasket. Its flat, well-watered land produces most of the country's rice, along with wheat, maize, sugarcane, lentils and mustard, and it holds many of Nepal's industrial towns and busiest border crossings with India. Once heavily forested and feared for malaria, much of the region was cleared and settled in the twentieth century after the disease was controlled, and it is now one of the most populous and economically important parts of the country.
What to do
- Track rhinos and tigers on a jungle safari in Chitwan or Bardia.
- Visit the sacred gardens and monasteries of Lumbini.
- Take a canoe trip to spot gharial crocodiles and waterbirds.
- Stay in a Tharu village to learn about lowland culture and cuisine.
- Cross to the holy Hindu city of Janakpur, with its grand Janaki Temple.
Getting around
The Terai is served by Nepal's main east–west highway, the Mahendra Highway, which links its towns and park gateways, and by several airports including Bharatpur near Chitwan and Bhairahawa near Lumbini. Roads up into the hills connect the plains to Kathmandu and Pokhara, so the region is easy to combine with the rest of the country. Most travellers reach Chitwan by road or short flight from Kathmandu or Pokhara.
Fitting it into your trip
The Terai pairs naturally with the cooler regions to the north. Many travellers combine a few days in the lowlands with the cultural hill region and a trek in the Himalaya region.

Frequently asked questions
What is the Terai in Nepal?+
The Terai is the low, flat strip of fertile plain that runs along Nepal's southern border with India. It lies mostly below 300 metres, forms part of the wider Indo-Gangetic plain, and is the country's most productive farmland as well as the home of its major lowland wildlife parks.
How hot does the Terai get?+
The Terai is the hottest part of Nepal. Pre-monsoon temperatures in May and June regularly climb to 35–40C with high humidity, while winters are mild and pleasant at around 10–25C. The summer monsoon brings heavy rain that can cause seasonal flooding across the plains.
What wildlife lives in the Terai?+
The Terai protects some of Asia's most iconic species, including the greater one-horned rhinoceros, the Bengal tiger, wild Asian elephants, gharial and mugger crocodiles, and over 500 bird species. Chitwan and Bardia national parks are the best places to see them on jeep, walking and canoe safaris.
When is the best time to visit the Terai?+
October to March is the most comfortable window, with warm, dry days ideal for wildlife safaris and clearer sightings as the grass is cut. Avoid the scorching pre-monsoon months of May and June, and expect heavy rain and possible flooding during the June–September monsoon.
