In the Mont Blanc region of the French Alps sits a skyward-reaching peak called the Aiguille du Midi. The peak's name translates as "Needle of Noon" because, when viewed from the French town of Chamonix, it acts as a natural sundial.
Adventure seekers can easily ascend the precipitous mountain thanks to the Téléphérique de l'Aiguille du Midi, a cable car built in 1955 that makes a 9,209ft (2,807m) climb to the peak. Until recently, the Aiguille summit was home to a viewing platform, café and gift shop. In December 2013, however, a glass box called "Step Into the Void" opened to the public, offering thrill-seekers the opportunity to step out above a drop of 3,395ft (1,035m).
