Lonely Planet the world’s largest selling travel guide book declares Everest Base Camp trekking is one 10 best treks in the world. It has ranked Everest Base Camp as the 4th best trekking trail after GR20, France (1st), Inca Trail, Peru (2nd), Pays Dogon, Mali (3rd). The book explains Everest Base Camp trekking in this way for its declaration: Reaching a height of 5,545m (18,193ft) at Kala Pattar, this three-week trek is extremely popular with those who want to be able to say, ‘I’ve been to the base of the world’s highest mountain’. The difficult trek passes undeniably spectacular scenery and is trafficked by Sherpa people of the Solu Khumbu. The heights reached during this trek are literally dizzying until you acclimatize to the altitude, and the continuous cutting across valleys certainly has its ups and downs.
