The Everest Base Camp trek is a 14-day Nepal trekking adventure through the
Khumbu region to the foot of the world’s highest mountain at 5,364 m. After
a 30-minute flight to Lukla, the EBC trek passes Sherpa villages, Namche
Bazaar and Tengboche Monastery, with two acclimatization days built in and a
sunrise climb to Kala Patthar (5,644.5 m) for the best view of Everest. The
best seasons are March to May and September to November.
