As per Deadline, filming took place at South Base Camp on March 24, 2014. The production team gained permission from the Nepalese government to briefly shoot on location for authenticity. However, the bright sunlight was replaced with artificial lights in the studio.
Tribhuvan International Airport, Kathmandu, Nepal

As per My Republica, Josh Brolin and John Hawkes began filming Everest (2015) at the Tribhuvan International Airport in Kathmandu on January 14, 2014. In the movie, the airport serves as a crucial setting where the climbers land and plan the next steps of their expedition.
The film not only includes scenes from the airport but also features its nearby streets, creating the background of Nepal. Additionally, filming continued the next day at Tenzing-Hillary Airport in Lukla. The production team then moved to Namche Bazaar, which provided the rural scenery of Nepal.
The Dolomites and Rome, Italy

The Dolomites, a mountain range in Italy, served as a background to mimic the scenery of Mount Everest. This was done mainly due to the harsh weather conditions and lack of sunlight in the Everest base camps.
