1. The Danakil Desert, Eritrea, Ethiopia
It’s hard to imagine why anybody would want to spend a vacation in this literal “Hell on Earth” where temperature can reach 120F (50C) and volcanic eruptions that spew deadly gases into the air are everywhere. But it happens. However, if you think you’re going to manage to travel there solo, think again. The Eritrean government doesn’t cotton to your particular brand of crazy. It’s only possible to go there with an experienced guide.
2. Yosemite National Park’s Half Dome, California
Looking to laugh at Death in the face? This is the place to do it. It takes an entire day to climb to the top and can burn as much as 10,000 calories, which sounds great if you are into fitness. But major problems arise when you reach the last 400 feet, which is nearly vertical and requires the aid of metal cables while climbing slippery rocks. More than 60 people have been killed attempting this.
