HI! Recently went for a trek to Annapurna Base Camp ( ABC) , Nepal with Sujoy Das who runs South Col Expeditions. Every aspect of the trek, stay , food, safety was personally looked into by Sujoy. He is also extremely knowledgeable on the Himalaya’s and a top rated photographer. He has authored the lonely planet guide on Nepal ( Indian Edition). He shares his knowledge freely on any aspect of travel or photography. I would very highly recommend South Col for any of their future treks and hopefully would be trekking again with him soon.
