I was with Nepal Mountain Trekkers and my great guide Shiva in Langtang Valley and Gosaikunda. It was all well organized and I had an incredible two weeks in this fantastic landscape. Shiva knows everything and knows how not to tell too much at the same time, so you can enjoy the peace and nature. Even at the end of our trek, he did not invite me to his village where I could see real Nepalese life. I can recommend this agency and would book here again my trip. Thanks for everything:)
