The bulk of Mera, officially the highest of Nepal's permitted trekking peaks, lies to the south of Everest and dominates the watershed between the wild and heavily wooded valleys of the Hinku and Hongu Drangkas. This trek offers the chance to venture into a little visited and as yet unspoilt region of Nepal where the hillsides are still densely forested and a need to be self-sufficient is essential. There is also, of course, the pleasure of going above 21,000 feet. Both the Hongu and Hinku valleys remain uninhabited although there are Kharka in the Upper Hinku basin where Sherpas from the south, near Pangkongma, graze their animals during the fertile monsoon. The upper Hongu Basin is truly a mountain wilderness, a place of massive moraines, glacial lakes and spectacular peaks that include Charmlang and Baruntse.
