Rongbuk Valley and the Rongbuk Glacier are located in the Himalaya of southern Tibet. Climbing expeditions and trekking parties use this glacier to reach the Advanced Base Camp of Mount Everest at the upper end of the East Rongbuk Glacier. From there, climbing expeditions try to summit Everest by the North Col and the northeast ridge.
At 17,000 feet the Rongbuk Valley post office is claimed to be the world’s highest located post office. It opens at 11am every day from April to August and costs 3 Yuan (£0.28) to send a letter to Beijing and 9 Yuan (£0.85) to send a letter to England.
