Taking the guide is not at all essential for Everest Base Camp Trek but it is strongly recommended by us. Due to its altitude, the Everest trek is a challenging task, as you ascend higher at the Himalayas, there is a possibility of avalanches and heavy snowfall. This might create problems for solo trekkers as the trail might be miscalculated. Due to fewer dwellers at the Himalayas, you will encounter fewer trekkers and locals, and in time of need, there will be no one to help you. So, at least you will need a local guide to help you to accomplish your trek to Everest Base Camp more easily.
