During the 30-minute flight from Kathmandu to Lukla (9,186ft), you will enjoy one of the most beautiful air routes in the world culminating on a hillside surrounded by high mountainous peaks. At Lukla, a gateway destination from where your trek begins, you meet your other trekking crew members and begin packing and arranging with them. From Lukla, you start trekking. At one hour’s gradual descent, you will be at a Cheplung village from where you have a glimpse of Mt. Khumbila (18900 ft), a sacred mountain which has never been climbed. From Cheplung, you then gradually descend until you reach Phakding and spend the night.
