 This route takes trekkers from Lukla to Namche Bazaar, Tengboche, Pangboche, Dingboche, Lobuche, and on to Gorak Shep.Most trekkers stay overnight there, as their trekking permits will not allow them to camp at Everest Base Camp.Also, Gorak Shep provides the best "launching pad" for an ascent of Kala Patthar, which looks like a giant dune looming over the lakebed.
