Mountains, for me, have always been the manifestation of the great universal force. Also, all my life, I have seen my father going on long treks. His experience during the Annapurna Base Camp Trek is something that will stay with me forever. 

Further, growing up, battling with obesity and oodles of health issues, I could not be a trekker like my father. However, that did not diminish my love for the mountains. 

The hardest mountains to climb, especially, have always created a sense of intrigue for me. Also, that day, I was watching the second season of the BBC’s Extreme Podcast. 

I was impressed by how Natalia Mehlman Petrzela, the host and historian, narrated the story of the newlywed couple, Cecilie Skog and Rolf Bae, as they climbed K2. 

Now, seldom will you find a couple planning their honeymoon by climbing the K2. So, their story was one-of-a-kind, and you must also watch it if you feel this unavoidable pull toward mountains. 

In fact, I was so mesmerized by the podcast and the way it stirred all my memories related to mountain climbing that I decided to write this Dream and Travel Guide on the hardest mountain to climb in the world.

K2 or Mount Godwin Austen is the hardest mountain to climb in the world. It was kind of a shocker for me when, in 2024, the Gilgit-Baltistan Tourism Department confirmed issuing 175 permits to climb the peak. 

Now, a lot has changed, and climbing K2 is more commercialized these days. However, the mountain could not be conquered in the winter season before 2021. During the summer itself, the temperature in the mountain remains around -60 degrees C.
