It takes about eight days to slowly walk the 65 kilometres from the village of Lukla to Everest Base Camp, which sits at an elevation of 5,364 metres (17,590 feet). And even though this is the most mentally and physically challenging trek I've ever done, it's also the most rewarding. This is not just a hike through the highest mountains in the world; it's a spiritual journey through another culture that pushes you out of your comfort zone the higher you hike.
