The Imja Khola (Nepali: इम्जा खोला) is a tributary of the Dudh Kosi in Nepal. It drains the slopes of Mount Everest. The Khumbu Glacier melts into the Lobujya (Lobuche) River, which flows southward as the Imja Khola to its confluence with the Dudh Kosi at Tengboche.[2]

The Imja Khola collects water from the Imja Glacier through the Dingboche Valley.[3]

The Imja Khola is on the trekking route in the Everest base camp region, between Thyangboche and Dingboche at 4,360 metres (14,300 ft). During the Everest Base Camp Trek, trekkers cross a suspension bridge, over the Imja Khola, moving towards the village of Dingboche. Dingboche, the 'Summer Valley; of the Khumbu has a kilometer-long wall built to protect the village's crops from the cold winds that descends down the Imja Valley.[4] There is a monastery at Pangboche at 3,900 metres (12,800 ft).[5] The trek is through a Rhododendron forest.[6]

It is also on the trekking route to Chukhung and the Imja Tse or Island peak.[7]
