I will be in Shimla in the later month of June for a conference which would last a day after that I have 5 days free which I would like to spend somewhere around Shimla. The kind of places I would like see are Kalpa and Kaza and I am thinking of visiting both of these places. Before I plan any further I have a few questions. What is the route from Shimla to Kalpa/Kaza like? Would you suggest any other places or routes other than the ones I have mentioned? Would it be easy finding accommodation during the peak season if I don't prebook?
