Kathmandu and Pokhara in one place: what the trekking permits now require, which two windows the mountains are clear in, and how long the road between the two cities takes.
The things that change a decision — not a retelling of the guidebook.
Trekkers need a TIMS card and a national park or conservation area permit, and since 2023 solo trekking in the national parks requires a licensed guide. Agencies in Kathmandu and Pokhara arrange all of it in a day; the rules do move, so confirm the current position before you fix a plan.
October and November give the clearest mountain views of the year and the busiest trails. March and April are warmer, hazier and bring the rhododendron forests into flower. The monsoon from June to September closes most of it; winter is clear but very cold at altitude.
A small plane out of Kathmandu flies along the Everest range and back, with every passenger guaranteed a window. It runs in the early morning only and is cancelled for cloud — which in October and November is rarely a problem and in summer usually is.
Two hundred kilometres, on a road that is being rebuilt and is slow. The alternative is a twenty-five minute flight. Tourist coaches are comfortable and leave early; the scenery is good and the journey is still most of a day.
The Durbar squares of Kathmandu, Patan and Bhaktapur lost temples and much has been rebuilt, but restoration continues and some structures remain scaffolded. It is part of what you are looking at rather than a disappointment.
Nepal is inexpensive and largely a cash economy. Kathmandu and Pokhara have ATMs; the trekking routes do not, and teahouses charge for hot water, charging and wifi in rupees. Draw what you need before you leave the city.
What is open, how busy it gets, and when to book ahead.
