Hello, I'm planning a trip to Spiti Valley within next few months. We are a couple and have some plans for night sky photography. That's why we would prefer to spend one or two nights in places like Dhankar or Langza. I heard these places have the option of some homestays now a days, specially in Dhankar. Can you give some info on this? Any contact of a reliable tour operator who provides personal vehicle with driver will be welcome also.
