Climbing K2 is considered the top mountaineering expedition in the whole world. "K" stands for the Karakoram range, and "2" denotes its position as the second-highest peak listed. Located near the Baltoro Glacier in the extreme north of Gilgit Baltistan, K2's boundary crosses between two countries.

To reach the base camp of K2, climbers must navigate through action-packed and riveting hazards. George Bell, a famous American climber, named it the "Savage Mountain" in 1953, famously declaring that "K2 is a savage mountain that tries to kill you." It is also alternatively called "The King of Mountains" and "The Mountaineers' Mountain."

K2 has never been climbed from its eastern face. Approximately 400 people have successfully climbed K2, while around 85 deaths have occurred during attempts. Climbers face key difficulties, including extremely high altitude and lack of oxygen, severe storms lasting several days resulting in fatalities, and the steep and exposed nature of the routes.

The standard route, used by 75 percent of climbers, is the Abruzzi Spur, characterized by a series of rocks, snow and ice, black pyramids, and bottlenecks. The North Ridge route is rarely climbed due to its challenges.
