go to site Sandakphu Phalut Trek or Singalila Ridge Trek is one of the best treks that offer breathtaking mountain views. It is the only trek in India where one can see Mt. Everest (Tallest), Kanchenjunga (Third), Lhotse (Fourth) and Makalu (5th) together in a single frame. Spring months are great for trekking as days are longer with beautiful rhododendrons along the trail and warmer nights. However you have to be lucky to get views as clear as winter months.
