Lukla (2,860m) is where the Khumbu begins for almost every trekker — a small mountain town built around the famous Tenzing-Hillary Airport, gateway to the Everest region. The airport's short, sloping runway and dramatic valley setting make the approach one of the most exciting (and anxiety-inducing) short flights in aviation. The 25-minute hop from Kathmandu, in a small turboprop threading between cloud-covered ridges, is an experience in itself.
The town itself is functional but atmospheric. A single street of guesthouses, bakeries, gear shops, and porter agencies leads uphill from the airstrip. At dawn on departure day, the airport fills with trekkers and porters, the air is cold, the chai stalls are busy, and the mountains loom in the early light. On arrival, the smell of cooking fires, juniper smoke, and altitude-thin air is an immediate signal that you are somewhere genuinely different.
From Lukla, the trail descends to Phakding and then climbs to Namche Bazaar (one to two days). Helicopter evacuations for altitude sickness or injuries also land at Lukla before transferring patients to Kathmandu. In high season (October), flight delays can strand trekkers for days; build flexibility into your schedule when flying back.
