Namaste! I am planing to go trekking in Langtang region, starting around October 5th (I will be enjoying Dasain festival before in KTM).

Attached is a map with a blue line showing what trail I wish to follow.
I have been trekking already quite a lot in Nepal for the last 3-4 months (Dolpo, Mustang region, Dhaulagiri). I am in good shape, maybe still acclimatized a bit, but somehow I walk relatively slow and take lots of pictures on the way (that slows me down 🙂 ). My visa expires on Oct 31st and I need to be back in KTM before.
