We start trekking along the high ridge to the west of the Helambu valley, passing through Sherpa and Tamang villages until we cross the Laurebina Pass (15,121 ft). We descend to the Gosaikunda lakes which are sacred to both the Hindus and Tibetan Buddhists. We descend further into the remote Langtang valley, a National Park and home of the snow leopard, the Himalayan Thar, the Red Panda and musk deer. The valley is dominated by the 7,246 meter Langtang Lirung to the north, Gang Chhenpo (6,388 meters) to the south and Dorje Lhakpa (6,975 meters) to the east. As the trek nears the end at Dhunche we pass through the rice fields, rhododendrons and pine forests, which have numerous birds.
