For trekkers, trekking during autumn means cool temperature and high visibility. For photographers, lofty snow mountains and crystal lakes shine under the sunshine, in the background of pure sky, your masterpiece was born.
However, the “best” means the most suitable instead of the most popular. Traveling during the high season means you should travel with crowds and pay a higher price for the tour.
