The 1500-metre climb to the top of Half Dome is the most strenuous of Yosemite Valley’s day hikes, and it’s the last 120 metres that are the most dangerous. It’s a near-vertical climb, and while there are ladder-like metal cables to help you reach the summit without rock climbing equipment, falling off them could be deadly. And let’s not forget that Half Dome is basically a huge lightning rod, and in 1985, lightning struck five friends on the park’s tallest granite peak, killing two and injuring three.
