via Ganesh Himal Base Camp side trek (2 days)
Manaslu Region, Nepal

Highlights: Gumba Lungdang and Ganesh Himal Base Camp

Difficulty: challenging

It's a steep climb to the small nunnery of Gumba Lungdang preached beneath the towering peaks of the Ganesh Himal but well worth the effort for the breathtaking views and serenity of this little visited gompa.

Weather Conditions in September

change start

Mid-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‘Fall Season’ historically the monsoon would end in mid-September, however in recent years the monsoon has officially withdrawn in early October.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.
