How long does it take to trek to everest from Lukla, Nepal?
I’m going to Nepal in september and am just wondering how long of a trip i should make it before heading to my next country. I’m looking to spend a few days in Kathmandu and even venture down to the southern part of the country, but obviously everest is #1 on the list.
It will take 8 days to reach Everest Base Camp from lukla.. for details please see..
