The Everest Base Camp trek is one of the most popular trekking routes in the Himalayas and is visited by thousands of trekkers each year. Trekkers usually fly from Kathmandu to Lukla to save time and energy before beginning the morning trek to this base camp. However, trekking to Lukla is possible. There are no roads from Kathmandu to Lukla and as a result, the only method of transporting large and heavy goods is by plane.
In 2015, it was noted that about 40,000 people per year take the trek from the Lukla airport to the Nepal Everest Base Camp.
From Lukla, climbers trek upward to the Sherpa capital of Namche Bazaar, 3,440 metres (11,290 ft), following the valley of the Dudh Kosi river. It takes about two days to reach the village, which is a central hub of the area. Typically at this point, climbers allow a day of rest for acclimatization. They then trek another two days to Dingboche, 4,260 metres (13,980 ft) before resting for another day for further acclimatization. Another two days takes them to Everest Base Camp via Gorakshep, the flat field below Kala Patthar, 5,545 metres (18,192 ft) and Mt. Pumori.
