We trekked from Dec 22 to jan 4th through Ruby valley and Pangsang pass at 3850mtrs with our guide Nauser. We spent Christmas night on Pangsang and although is was cold it was an amazing experience, one we ( myself and 2 teenagers, aged 12 and 14) will never forget. Each village we stayed in was truly authentic. We loved every village but our favourites were chalish, tipling, Lapa and somdang. The hot springs near to Chalish are well worth the trek, to soak in the hot water was a very welcome relief. Our guide did everything to make sure we were safe at all times. He organised packed lunches for the long days where he knew we had no tea house to stop and get lunch at. He packed his backpack with fruit so that every night we had some fruit, he knew there was none available on the trek. This trek tested me partially due to the cold at night time and the snow we trekked through around pangsang( this made it difficult to use the trek so we had to walk the gravel road) but the sense of achievement on reaching Dhadingbesi was wonderful. I recommend Tej and all his staff with the absolute belief that they care about getting you through not only safely but that you create the most wonderful memories on the way. We are already planning our next trek, back to langtang to see some more of this wonderful place .
