Having reached Lukla, and survived the most dangerous airport in the world, we were now ready to start our 4 day trek up to Tengboche at 3,900m and then 3 day trek back. Tengboche was half way up the Everest Base Camp Trail, the base camp being at 5,500m and another 3 days trek past Tengboche. After some local lunch we arranged the sherpa porters and with our trekking guide Bir Bador we headed out through the town and onto the gentle first half day trek to Phakding. At the end of the town there is an arch marking the start of the Everest Base Camp Trail and the stone trail initially descends steeply making it an easy start to the trek. From Lukla to Phakding there is a drop in elevation of around 200m. It was mentally noted however that this easy first section would soon to become the difficult final section on our return to Lukla!
