At an altitude of 14,100 ft, Chandra Tal has to be one of the most beautiful lakes in the world. In spring time, flowers bloom majorly on the meadows whereas at night the sky comes alive with stars with a spectacular view of the Milky Way. In my view, September is the best time to visit Chandra Tal. It is cold but in terms of seeing flora, fauna, topography and for photography, this is the best time!
