Be Respectful of the Mountain
The trail is such a sacred place, which is what makes it so special. There are prayer rocks, prayer wheels, climber memorials, monasteries, and more along the way, and it's so important to be aware of the Nepalese traditions and respect them. For example, always walk to the left around prayer rocks for good luck and spin prayer wheels as you pass them. And please, if you need to go to the bathroom when you reach the Everest climbers memorial, wait a few more minutes until you leave that very special and emotional place (I kid you not, I saw more than a few people not respect it).
