Kathmandu

Introduction

Kathmandu is the capital of Nepal and the gateway to every trekking region — a UNESCO World Heritage valley with 7 monument zones, the only international airport in the country, and the launch point for all Himalayan adventures.

Situated in Kathmandu district at an altitude of 1,400 m (4,593 ft), Kathmandu is a key stop on the Great Himalayan Trail within the Helambu. Locally it is known as Kathmandu Valley. The nearest settlement is Lalitpur (Patan). Tribhuvan International Airport (KTM) — Nepal’s only international hub; domestic connections to Lukla, Pokhara, Jomsom, Jumla, Simikot, Taplejung, and more. Trekkers reach Kathmandu as part of the standard trekking route.

History

The Kathmandu Valley has been continuously inhabited for over 2,000 years and was the center of the Newar civilization; it became the capital of unified Nepal in 1768 when Prithvi Narayan Shah conquered it from the Malla kings.

The helambu has been a corridor for trade, pilgrimage, and mountaineering for centuries. Kathmandu has witnessed the evolution of Nepal’s trekking industry, from the early expeditions of the 1950s to the modern tea-house network that today supports thousands of trekkers each year.

Local traditions reflect the deep cultural heritage of the Himalayan peoples, including the Newar, Brahmin, Chhetri, Tamang, Gurung, Sherpa, Thakali, and dozens more. Oral histories, monastery records, and oral traditions document centuries of settlement, religious practice, and adaptation to high-altitude life.

Geography & Landscape

Kathmandu lies in the Helambu of Nepal at 1400 metres above sea level. The landscape is characteristic of the Nepal Himalaya — dramatic valleys, glacial moraines, alpine meadows, and forested ridgelines shaped by tectonic uplift and glacial retreat over millions of years.

The surrounding topography includes peaks, ridges, and river systems that define the trekking approach. The altitude places Kathmandu in the sub-tropical to temperate zone, with corresponding vegetation and wildlife.

Spring (Mar–May), Autumn (Sep–Nov). Spring (March–May) brings rhododendron blooms and warming temperatures, while Autumn (September–November) offers the clearest skies and most stable weather. Summer (June–August) is the monsoon season with rain, leeches, and reduced visibility, though the rain-shadow regions of Mustang, Dolpo, and upper Manang remain accessible.

Photography

• Photo spots: Swayambhunath at sunrise, Boudhanath stupa, Kathmandu Durbar Square
• Sunrise viewpoints: Swayambhunath, Nagarkot
• Sunset viewpoints: Nagarkot, Swayambhunath

The best light is in the golden hour after sunrise and before sunset. Carry a polarizer for the snow, a wide-angle for the landscapes, and a telephoto for distant peaks and wildlife. Always ask before photographing people.

Travel Tips

• Acclimatize gradually — do not gain more than 400–500m of sleeping altitude per day above 3,000m.
• Carry cash (Nepali rupees) — ATMs are rare above district headquarters.
• Pack layers — temperatures swing sharply with altitude and time of day.
• Bring a refillable water bottle and water purification tablets or a filter.
• Respect local culture — circumamberate stupas and mani walls clockwise, ask before photographing people, and dress modestly.
• Get travel insurance that covers helicopter evacuation above 5,000m.
