The mental plan almost everyone arrives with is the same: land, sleep, and be walking the next day. It is understandable, because nobody crosses half the world to see Kathmandu. But that plan runs into a very concrete administrative and logistical reality: almost everything you need in order to walk in the Himalaya is processed, bought or booked in this city, and nowhere else in the country as easily.
01 The city does a job nowhere else does
The underlying reason is the one that explains half of Nepal: geography. The country is narrow, mountainous and has very few roads that genuinely cross it, so almost all administrative and commercial infrastructure has concentrated in the one large flat valley there is. Kathmandu is not the gateway by habit: it is the gateway because there is no other door.
02 Permits: the one thing you cannot improvise
Walking in Nepal's mountain areas requires permits, and the system has several pieces: national park and conservation area entries, municipal fees in some districts and special permits for what are called restricted areas. They are processed in Kathmandu — and in some cases in Pokhara — before you leave, and they are checked at control posts along the route.
The awkward part is that the rules have moved a good deal in recent years: which document is needed in which area, whether a licensed guide is compulsory, whether you may walk unaccompanied in certain zones. That is why I am not giving you a list of fees and requirements here: any figure you read, this page included, may have changed. What is stable is where it gets resolved, and that is here.
What you buy in Kathmandu is not two days of city. It is the margin that keeps the trip working when something goes wrong.
03 Gear: what to bring and what to buy there
The rule that works best is to bring from home what touches your body and buy or rent the rest there. Broken-in boots, socks, a rucksack fitted to your back and a thermal layer: those travel with you, because breaking in footwear on a multi-day route is the fastest way to ruin it. Down sleeping bag, heavy down jacket, poles, rain covers and dry bags: those you rent or buy in Thamel for a fraction of the European price.
Leave at least half a day for this and do it on your first day, not your last. If something does not fit or is not in your size, having a spare day ahead turns a problem into an errand.
04 What the city will not give you
It is worth saying plainly so it does not catch you out. Kathmandu is not a place to rest. The centre is dense, traffic is constant, construction is permanent and the noise does not drop until late. If you arrive exhausted from a long flight planning to sleep twelve hours, choose your accommodation carefully and ask specifically for an inward-facing room.
Nor will it acclimatise you. The city sits at about 1,400 metres, a long way below the altitudes you are heading for. It is useful for shaking off jet lag and for one or two gentle walks along the valley rim, but do not count those days as acclimatisation: the real thing happens on the route, climbing slowly and sleeping low.
05 How to split the days
The structure that best absorbs surprises is two or three nights on arrival and one at the end. The arrival nights are work: permits and agency on day one, gear on day two, and the third in reserve in case something has gone sideways. The one at the end is not a luxury: it is the buffer you need if your flight back from the mountains runs late, which in this country happens routinely even in good season.
In the end the question is not whether Kathmandu competes with the mountains, because it does not. The question is whether you will reach the mountains with everything settled or with three loose ends. Two well-planned days in the city are what separates the two, which is why it is worth treating it as part of the trip rather than the wait before it starts.
