Phakding to Namche Bazaar hike is considered the toughest day of the EBC trek by many. First half is a constant up and down along the Dudh Koshi (milk river). The second half after lunch is a straight climb for over 3 hours. Murder!
The 13 km distance combined with over a 3000-foot elevation gain will be the most strenuous combination in this Trek. Happy to have that under our belt. The views speak for themselves. Shangri-La is all I could think of.
