Gokyo Valley has Nepal’s biggest glacier formation
The Ngozumpa glacier, below the sixth highest mountain in the world Cho Oyu in Nepal, at 36 kilometres (22 mi), is the longest glacier in the Himalayas. Ngozumpa Glacier is a large persistent body of ice. It flows slowly due to stresses induced by its weight.

the world’s highest freshwater lake system comprising six main lakes, of which Thonak Lake is the largest
summit pass located 5420 m above sea level. From the east: after Pheriche, the trail turns off the main Everest route near Dughla (4620m) and passes through the village of Dzongla. From the west: in the Gokyo valley, the trail turns off the Machherma-Gokyo route near the First Lake (4710m) and passes through the village of Thangnak (Dragnag). The pass can be tough and may require crampons on the little glacier on top.
It is advisable to obtain advanced information regarding the conditions before proceeding from Dzongla or Thangnak. Good views of Lobuche Peak.
