Langtang is a narrow valley situated just south of the Tibetan border and populated with Tibetans and Tamangs, who share a similar religion, language and clothing. The landscapes we cross are extremely varied: rice-terraces, gigantic rhododendron and fir forests and, at altitude, a rock and shrub wilderness against a backdrop of snowy peaks. The crossing of Ganja La pass is a high mountain itinerary and sometimes requires the use of ice axe and crampons. After the pass we reach the Helambu valley with its numerous and colourful Sherpa villages.
