Trekking companies in Nepal?
I want to go trekking in the Everest Region of Nepal. What are some responsible and reputable trekking companies?
There are numerous trekking agencies. You can check the list here.

So far I don’t have any direct experience with trekking agencies but this one is considered good (awarded many times).

It’s just a general speculation coz I am from Nepal but, you have to check a few and compare the price, schedules, facilities and everything.
Good Luck in your Trekking…
