2Mount Everest, Nepal

Mount Everest tends to attract an extreme variety of tourists. That is, those who want to climb to the top of the world’s tallest peak. Every year around 1,200 intrepid explorers will set off from the foot of the mountain. Unfortunately, only around half make it to the top, and some will die trying.
As you scale the mountain, the conditions become increasingly severe. Low oxygen levels, freezing temperatures, and fatal falls are just a few of the things people here must be careful of.
