Nepal, officially the Federal Democratic Republic of Nepal, is a landlocked country nestled in the heart of South Asia. Often described as perched on the crest of the Himalayas, understanding Where Is Nepal geographically is key to appreciating its unique and diverse landscapes, ranging from fertile plains to the world’s highest peaks. Bordered by China to the north and India to the south, east, and west, Nepal’s location is pivotal, shaping its climate, culture, and biodiversity. This article delves into the geographical tapestry of Nepal, exploring its varied relief and intricate drainage systems that define this captivating nation.
Nepal’s terrain is predominantly mountainous, with approximately 75% of its landmass covered by mountains, presenting some of the most challenging landscapes on Earth. From its southern borders stretching towards the north, Nepal is geographically segmented into four primary belts, each running from east to west across the country, creating distinct ecological and geographical zones. These zones offer a dramatic shift in landscape as one travels from the Indian border towards the towering Himalayas.
The southernmost belt is the Tarai, a low-lying, flat, and exceptionally fertile region directly adjacent to India. This area is an extension of the Gangetic Plain and is crucial for agriculture in Nepal. The Tarai’s width varies, ranging from less than 16 to over 20 miles, and it narrows in several places. The southern part of the Tarai is characterized by a 10-mile wide strip of rich agricultural land, vital for crop production. Conversely, the northern section, which merges into the foothills, is a marshy environment, teeming with wildlife and historically known for being malaria-endemic.
Moving north from the Tarai, the landscape ascends into the forested Churia foothills and the Inner Tarai zone. The Churia Range rises sharply, forming near-perpendicular escarpments reaching altitudes over 4,000 feet. Between the Churia Range to the south and the Mahābhārat Range to the north, lie broad basins elevated between 2,000 to 3,000 feet, approximately 10 miles wide, and 20 to 40 miles in length. These basins are known as the Inner Tarai. Historically dense with forests and savanna grass, many areas of the Inner Tarai have been cleared for timber and agricultural land.
A complex network of mountain ranges, spanning about 50 miles in width and varying in elevation from 8,000 to 14,000 feet, lies between the Mahābhārat Range and the Great Himalayas. The Mahābhārat Range is marked by steep southern escarpments and gentler northern slopes. North of this range, enclosing the Kathmandu Valley, are the higher ranges of the Inner Himalaya, also known as the Lesser Himalaya, with peaks perpetually covered in snow. Within this mid-mountain region, the Kathmandu and Pokharā valleys are prominent flat basins. These valleys were once lakebeds, formed by the accumulation of fluvial and fluvioglacial deposits carried by rivers and glaciers during the Pleistocene Epoch.

The Great Himalaya Range, the northernmost geographical belt, soars in elevation from 14,000 to over 29,000 feet. This range is home to some of the world’s highest peaks, including Mount Everest, Kānchenjunga I, Lhotse I, Makālu I, Cho Oyu, Dhaulāgiri I, Manāslu I, and Annapūrna I, all exceeding 26,400 feet. Apart from scattered settlements in high-altitude valleys, this region is largely uninhabited due to its extreme conditions.
The drainage systems of Nepal are as crucial to its geography as its relief. The Kathmandu Valley, the nation’s political and cultural heart, is drained by the Bāghmati River. This river flows southward, passing the revered Paśupatinātha temple and exiting the valley through the deep Chhobar gorge. The valley’s geological composition includes sandy layers from ancient lakebeds that act as aquifers, resulting in springs throughout the Kathmandu Valley. These springs, often channeled through decorative stone dragon mouths, are vital sources of water for drinking, washing, and irrigating rice nurseries before the monsoon season.
The Pokharā Valley, located 96 miles west of Kathmandu and drained by the Seti River, is another significant flat lacustrine basin. Remnants of ancient lakes are still present in the Pokharā basin, with Phewa Lake being the largest, stretching approximately two miles long and nearly a mile wide. To the north of the Pokharā basin rises the majestic Annapūrna massif of the Great Himalaya Range.
Nepal’s major rivers—the Kosi, Nārāyani (Gandak), and Karnāli—flow southward across the Himalayan ranges, creating transverse valleys with deep gorges. These gorges often reach depths of several thousand feet from the crests of the bordering ranges. Interestingly, the watershed of these major rivers lies north of the highest Himalayan peaks, typically in Tibet.
These rivers possess significant potential for hydroelectric power development. Nepal has collaborated with India on irrigation-hydroelectric projects on the Kosi and Nārāyani rivers. Discussions have also been held to harness the immense potential of the Karnāli River. The Kulekhani hydroelectric project, a 60,000-kilowatt facility funded by the World Bank, Kuwait, and Japan, commenced operations in 1982, marking a step towards utilizing Nepal’s water resources for energy.
While the upper reaches of Nepalese rivers, flowing through mountainous regions, generally avoid flood issues, the low-lying Tarai plain is prone to severe flooding. Conversely, the rivers and smaller streams in the Tarai, especially those with reduced dry season flow, face pollution from domestic waste. Urban and village expansion without adequate sewage disposal, coupled with increasing industrialization in the Tarai, has led to polluted surface water in the Kathmandu and Pokharā valleys, as well as the Tarai region, rendering it unsuitable for drinking without treatment.
In conclusion, where is Nepal is not just a question of geographical coordinates but an inquiry into a land of extraordinary geographical diversity. From the plains of the Tarai to the towering heights of the Himalayas, and sculpted by intricate river systems, Nepal’s geography is a defining feature of its identity, influencing every aspect of life within this remarkable Himalayan nation.
