As a solo trekker, it was just me and my guide, Ganesh. Reading the other reviews from other users, you will see consistent praise for what Ganesh brings to your EBC experience. He is a professional who takes his job very seriously, with deep intimate knowledge of the mountains and its trails, and also takes his classes and certifications seriously to ensure he is able to prevent altitude sickness. I bring this up as many other trekkers I ran into experienced altitude sickness (and some had to be evacuated), while I was able to complete the trek without even a headache. Not only is he a professional, but he’s humorous, amiable, friendly, etc. just an all-around amazing guy and companion to have on the trek! He adjusts the trek’s pace according to your ability.
