Geography of Nepal

Geography of Nepal: Regions, Mountains, Rivers, and Climate Zones

The geography of Nepal has more elevation change in one small country than almost anywhere else on Earth. Nepal covers just 147,516 square kilometers, yet it rises from 59 meters near the Indian border to 8,849 meters at the summit of Everest.

This dramatic range shapes everything about the country, from its climate to its culture to where people choose to live. Understanding the geography of Nepal is the best starting point for trekking in Nepal, since altitude decides the weather, terrain, and even which ethnic communities you'll meet along the trail.

Geography of Nepal at a Glance

Where is Nepal Located?

The geography of Nepal places it squarely in South Asia, landlocked between two giants. China's Tibet Autonomous Region borders it to the north, while India wraps around the east, south, and west.

• Nepal is between roughly 26°N and 30°N latitude, in the same general band as the U.S. state of Florida.
• A narrow strip of India's West Bengal, called the Siliguri Corridor, separates Nepal from Bangladesh.
• Despite sharing Florida's latitude, Nepal's elevation makes its climate almost unrecognizable by comparison.
• The country stretches like a rectangle tilted northwest to southeast, squeezed between two of the world's most populous nations.

How Big is Nepal?

Questions about the size of Nepal come up constantly, so here are the exact figures:

Despite covering less than 0.1% of Earth's land surface, the geography of Nepal contains some of the most extreme terrain on the planet. 

That combination of small size and massive elevation range is exactly what makes trekking in Nepal such a compelling place.

The Three Geographical Regions of Nepal

The geography of Nepal divides into three parallel regions running east to west, and each one feels like a different country.

1: Terai Region (Lowlands)

• Elevation ranges from 60 to 300 meters above sea level.
• The Terai covers about 17% of Nepal's total land area but holds close to half its population.
• Known as the "granary of Nepal," this region produces rice, wheat, and sugarcane on fertile plains.
• The Tharu, Maithili, and Bhojpuri-speaking communities call this region home.
• Wildlife safaris here reveal Bengal tigers, one-horned rhinos, and gharial crocodiles in national parks like Chitwan.

Visit this landscape yourself on a Chitwan Jungle Safari Tour or explore more options under Jungle Safari in Nepal.

2: Hilly Region (Pahad)

• Elevation ranges from 300 to 3,000 meters.
• This middle belt covers 64–68% of Nepal's land area and holds roughly 43% of its population.
• The Kathmandu and Pokhara valleys are within this region.
• Newar, Gurung, Magar, Tamang, Rai and Limbu communities live across these hills.

Learn more about the communities who call this region home on our People of Nepal guide, or take a closer look at the valley itself with a Sightseeing Tour in Nepal.

3: Himalayan Region (Himal)

• Elevation ranges from 3,000 meters to the summit of Everest at 8,849 meters.
• This region covers 15% of Nepal's land area and holds only 6–7% of its population.
• Eight of the world's fourteen 8,000-meter peaks stand here, including Everest, Kanchenjunga and Annapurna.
• Sherpa, Tamang, Manangi and Dolpo-pa communities have adapted to life at extreme altitude.

If high mountains are what drew you to Nepal in the first place, start with our Everest Region Treks, Annapurna Region Treks, or Manaslu Region Treks.

Comparing Nepal's Three Regions

The geography of Nepal concentrates most of its population in the lowest two regions, while the mountains that draw trekkers from around the world stay sparsely populated.

Nepal's Eight-Thousanders and Major Mountain Ranges

No discussion of the geography of Nepal is complete without its mountains, since this is what Nepal is most famous for.

1. Mount Everest – 8,849 m, world's highest peak
2. Kanchenjunga – 8,586 m, third highest in the world
3. Lhotse – 8,516 m, fourth highest in the world
4. Makalu – 8,463 m, fifth highest in the world
5. Cho Oyu – 8,201 m
6. Dhaulagiri I – 8,167 m
7. Manaslu – 8,163 m
8. Annapurna I – 8,091 m

Climate Zones of Nepal by Altitude

As the geography of Nepal spans such extreme elevations, the country experiences climate zones that shift dramatically over short distances.

For a full month-by-month breakdown of what to expect in each season, see our detailed Climate of Nepal guide.

Rivers and Water Systems of Nepal

Rivers cut through nearly every part of Nepal, and they've shaped both the landscape and its history.

Rara Lake, tucked in far-western Nepal, holds the title of the country's largest lake. If river adventure interests you as much as the mountains do, check out our Rafting in Nepal trips.

National Parks and Conservation Areas of Nepal

Nepal protects a remarkable share of its land, and this matters for anyone planning a trek or safari.

• Sagarmatha National Park protects the Everest region and covers 1,148 sq. km.
• Chitwan National Park safeguards the Terai's tigers and rhinos across 952 sq. km.
• Annapurna Conservation Area is Nepal's largest protected area at 7,629 sq. km.
• Manaslu Conservation Area covers 1,663 sq. km around the eighth-highest mountain on Earth.
• Bardiya National Park protects 968 sq. km of Terai wilderness.
• Langtang National Park spans 1,710 sq. km just north of Kathmandu.

Altogether, protected areas cover close to a quarter of Nepal's total land area. 

Many of these parks overlap directly with our Remote Area Treks and Easy and Short Treks, so the trail you choose often runs straight through one of these reserves.

How Nepal's Geography Shaped Its History and Culture?

The geography of Nepal didn't just create dramatic scenery; it shaped the country's entire political and cultural story.

• The Himalaya acted as a natural barrier, making northern invasion difficult and helping Nepal avoid colonization.
• Nepal's mountainous terrain also slowed unification, keeping the country's many ethnic groups culturally distinct for centuries.
• The Kathmandu Valley became a major trading hub, sitting directly along trans-Himalayan routes linking India and Tibet.
• Nepal's position between two regional powers shaped agreements like the 1816 Sugauli Treaty, which still echoes in its foreign policy today.
