We are planning to trek from Lukla to Everest Base Camp. Has anyone(born and raised in Nepal) trekked this route before? There are lots of info on Everest Base Camp trekking in internet but they are focused for foreigners. How many days would be required for Lukla-Base Camp-Lukla round trip for an average group of 20-25 Nepalese youths who have already done couple of trekking expeditions such as ABC and Gosaikunda in Nepal. (We are planning to do within a week)...And..what would be the average cost per person? Any suggestions or pointers would be highly appreciated.
