I slept at the base camp of the highest mountain in the world and it was the lifetime expreience. My guide Shiva was a humble guide with high-value experience. It was a bit cold up there at night but it was worth it. I will never forget the night and the million-dollar sleep there. We had best view at the night of the towering mountains and the vicinity area. Hike to Kala Patthar was the other major highlight of this trek. Absolutely amazing adventure.
