Kala Patthar is the spot for those who wish to see an up-close unobstructed view of Mount Everest. And at 5,643 meters, Kala Patthar is more than just a viewpoint. Given that it is higher than four of the seven summits, a trek to Kala Patthar is a journey. Kala Patthar is actually one of the few spots from which you can see an unobstructed view of Mount Everest. Because of the topography, the Lhotse wall blocks Everest from most vantage points.
