In early April, it was reported that at least 250 climbers on 27 expeditions were headed for Mount Everest. This grew to 289 climbers from 34 groups by April 20. All permits purchased for the spring season of 2015 were extended for two years, allowing those who had been unable to climb due to the earthquake and subsequent avalanches to return. 70 people returned in 2017 under this program.
