The tour guide and bus driver in Spiti Valley were excellent, accommodating and friendly. The valley is unique and beautiful, I am glad to have visited it now. The mountains were picturesque, with distinctive patterns of stone formation on the sides of the mountains, and very beautiful monasteries with peaceful villages. Chandrataal is another great experience to see a very beautiful lake between the snowy mountains and see our own galaxy at night. This is an adventure one should experience. There were some issues though, the bus from Delhi to Manali and vice versa was not good, they could have been better like HRTC or similar which is actually Volvo. The bus in Spiti Valley also could have been better as specially last rows were very uncomfortable on rough paths. It gave two of our family members back pain. The hotel in Kaza could have been better as the bed was very hard and uncomfortable to sleep on. The locations were very beautiful and very unique, I would recommend all my friends to visit the valley with Thrillophilia if the changes mentioned are taken care of.
