Everest is the tallest mountain in the Himalayan range, the youngest mountain range. Scientists believe that Everest is growing on average 4mm per year. As a part of the Himalayan range, Everest sits surrounded by very tall mountains – including Lhotse (8,516 m), Makalu (8,463 m), Cho Oyu (8,201 m), Khumbutse (6,665 m), and Nuptse (7,861 m). The whole region elevates rapidly, so trekkers need to acclimatize on their way to Everest Base Camp.
