The Everest Base Camp Trek on the south side, at an elevation of 5,364 m (17,598 ft), is one of the most popular trekking routes in the Himalayas and about 40,000 people per year make the trek there from Lukla airport. Trekkers usually fly from Kathmandu to Lukla to save time and energy before beginning the trek to the 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.

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 the central hub of the area. Typically, at this point, climbers allow a day of rest for acclimatization. They then trek for 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 KalaPatthar, 5,545 meters (18,192 ft) and Mt. Pumori.

On 25 April 2015, an earthquake, measuring 7.8 on the moment magnitude scale, struck Nepal and triggered an avalanche on Pumori that swept through the South Base Camp. At least 19 people were said to have been killed as a result. Just over two weeks later, on May 12, a second quake struck, measuring 7.3 on the MW. Some trails leading to Everest Base Camp were damaged by these earthquakes and needed repairs.
