I had a great experience with Samden and Birendra on the ABC trek. These guys are great guys, friendly, humble, honest, and very polite. I have traveled though out the world quite a bit and was a bit skeptical of the whole ” tour/guide ” thing, not sure what to expect. But I had a great tie with these guys, they looked out for me, were social, yet gave me space and went at my own pace. I would recommend them to anyone without a doubt.
