Highlights:
Imja Tsho (Lake) and Kongma La Pass
Difficulty:
strenuous
Probably the least traversed of the classic three passes in the Khumbu region, the path to the Kongma La (5535 m) offers a spectacular but strenuous route between Chukhung and Lobuche. This pass offers unparalleled views of what many regard as one of the most beautiful mountains in Khumbu, the pointed spired of Ama Dablam. While in Chukhung, you may wish to spend an additional day and climb Chukhung Ri for a panorama of the Chukhung Valley, or hike to the alpine lake of Imja Tsho.
Weather Conditions in September
change startMid-September marks the start of the ‘Fall Season’ historically the monsoon would end in mid-September, however in recent years the monsoon has officially withdrawn in early October. While there is a good chance of precipitation, clear skies and lush, rice paddy terraced hills are your spectacular when it is not raining. The chance of rain decreases as the month progresses. The end of the monsoon means there is still a chance of the occasional heavy snowfall at high altitudes. Furthermore, high passes can have a lot of snow that has accumulated over the monsoon.
