Why trust this guide

Kathmandu is chaotic, dusty, ancient and completely unlike anywhere else. A valley city of Hindu and Buddhist temples layered over each other across centuries, it is where almost every Himalayan trek begins and ends, and where you will spend a few days at either end of the mountains getting permits, buying gear and drinking a great deal of tea.

Why it's worth the flight

The mountains, primarily — Nepal has eight of the world's fourteen highest peaks and a trekking infrastructure that lets ordinary people walk among them without technical climbing. But the Kathmandu Valley itself holds several UNESCO-listed durbar squares and a living religious culture that is genuinely extraordinary.

When to go

Two clear windows. October to November is the main trekking season — clear skies, stable weather, the best mountain views, and the busiest trails. March to May is the second season, warmer, with rhododendron in bloom and hazier views. Monsoon from June to September brings rain, leeches and cloud. Winter is cold at altitude but clear and quiet at lower elevations.

Where to base yourself

Book the mountains properly Trekking permits, guides and porters are regulated and requirements change. Arrange through a reputable agency rather than informally — this is a place where the cheap option can be genuinely unsafe.

What to eat

Dal bhat — lentils, rice and vegetable sides, refilled endlessly — is the national meal and the fuel of every trek. Momos, the dumplings, are everywhere and superb. Newari cuisine in the valley is a distinct and much older tradition worth seeking out. And Nepali tea, milky and spiced, is a constant.

Getting around

Taxis with an agreed fare, or the Pathao and inDrive apps in the city. Traffic and air quality are both poor — a mask is not an overreaction on bad days. For the valley towns, hire a car and driver for the day; it's inexpensive and saves hours. Domestic flights to trekking regions are weather-dependent and delays are routine, so build slack into your schedule.

The honest caveat

Kathmandu is polluted, congested and hard work. Earthquake damage from 2015 is still visible in places and restoration continues. Altitude is a serious medical consideration on any trek — ascend slowly, know the symptoms of altitude sickness, and take them seriously. Travel insurance covering high-altitude trekking and helicopter evacuation is not optional here.
