So many times we have seen local guides, picked up in Lukla, asking our guides which is the right trail.
We have four guides for every group of ten trekkers. Having more guides helps you on the trail when the risks are higher. There are lots of porters, trekkers, animals, rock fall, and drop offs along the way. You need to walk as a group and not be spread out across the trail. Make sure you have the best guides in support of your trek.  So many times we have seen local guides, picked up in Lukla, asking our guides which is the right trail.
