I was part of winter Spiti with tripwithnomads, as I was a solo traveler, they made sure that and made a batch that suits to all solo traveler so they can mingle with everyone and not get lost in big group of friends. My captain Pallavi Choudary was very supportive and made sure we are in good health through out our trip as it was a high altitude trip. She took care of us and also enjoyed with us like a friend. When it comes to stay in spiti during winter they gave a best suitable stay in all village. We also got good stays with hot water and heater facilities and some days not, which is adjustable. Overall it was good, I definitely try another trip with them again soon....
