It is entirely up to you whether to book your trek in advance over the internet or with a local business after you arrive in Nepal. In Kathmandu, numerous trekking firms provide Everest climbs, and booking with any of them is simple. However, we encourage that you plan the trip ahead of time so that you get to travel with confidence once you have booked and organized the trek before arriving in Nepal. When you plan and arrange the trek in advance, the firm takes care of everything from airport transfers to hotels in Kathmandu, flights to Lukla, permits, and route housing, as well as guides and porters.
