The Indian Himalayas span Himachal's Manali and Dharamshala (the Dalai Lama's seat), Uttarakhand's Yamunotri and Gangotri pilgrim sources, Sikkim's Kanchenjunga views, and Ladakh's high-altitude desert plateau.
Pre-monsoon with rhododendron forests in flower across Sikkim, Char Dham pilgrimage opening late April-May, and Manali and Shimla pleasant before summer rains.
Monsoon brings afternoon storms across most of the Himalayas, but Ladakh in the rain shadow stays dry, and Spiti Valley accessible by both Kinnaur and Manali roads.
Post-monsoon with crystal mountain views, Sikkim's Kanchenjunga at peak photographic clarity, and the autumn pilgrim season closing across Char Dham.
Cold winter with skiing at Auli, Solang, and Gulmarg, Dalhousie and Shimla snow-covered, and Hemis Monastery's masked dances late January aside.
