Although the Sleep at Everest Base Camp trek does not require any technical expertise of mountaineering, it is considered a moderate or a challenging trek in terms of grade. And this is just because of the high altitudes and the long duration day hikes. It is basically a long hike that becomes grueling because of the 14-day hike up and down the hill across diverse terrains. You must be mentally prepared to walk for 6 to 7 hours every day along with your backpack.
