A Nepal government committee formed after a bad mountaineering season on Mount Everest has recommended that climbers be required to have scaled tall peaks, undergone proper training, and possess certificates of good health and insurance that would cover rescue costs before attempting to summit.

A report by the committee released Wednesday said people must have successfully climbed a peak higher than 6,500 metres before they can apply for a permit to scale Mount Everest. Each climber would also be required to have a highly experienced guide.

Of the 11 people who died during the spring climbing season this year, nine were climbing on the southern side of the peak in Nepal, making it one of the worst years on the mountain.

The government was criticised for allowing too many climbers on the world’s highest peak.

Mountaineering authorities were also criticised for not stopping inexperienced climbers, who had difficulty coping with harsh conditions on Everest and slowed down other climbers on the trail, to the 8,850m summit.

The government is expected to amend its mountaineering regulations following the recommendations.

The March-May climbing season is when weather conditions are best for climbing the Himalayan mountain.
