The threat of Water Crisis in the world is real, the world saw the first major demonstration in the capital city of South Africa- Cape town. The city somehow survived due to the wittiness of the officials and delayed the threat till 2019.
A reality check has to be addressed in the capital city of Himachal, Shimla. The city that sees 20,000 tourists every day. It is probably the favourite hill station of your grandparents. The locals are urging you to please stay out and I would say the same.
Spiti is one of the most sought after destinations in India. Just like Mcleodganj, it's another one of the Indian Destinations which would give you a tibetan touch.
The dispersed villages in the vast lands of the trans-himalayan region shine in the shadows of the monasteries.
This is the season for travellers to visit Spiti and most people add Shimla and Kinnaur to their journey. So please change that and take this itinerary instead.
