Already home to one of the world's most famous, record-breaking cable-car rides, gondola enthusiasts in Vietnam (and they totally exist) are about to be in cable-car heaven.
A local construction firm wants to build the longest cable car system on the planet, and they want to build it INSIDE one of the world's largest caves. No, we are not making this up -- the Vietnamese are just that crazy.
The developer, Sun Group, hopes to build a seven-station, 6.6 mile-long cable car network (at a cost of $212 million) between three caves: Tien Son, Phong Nha, and Son Doong.
As awesome as it sounds, though, the project is not without its critics. As a protected UNESCO World Heritage site, Son Doong could suffer under the weight of a cable car attraction and the throngs of tourists it would bring. Currently, the cave is limited to a mere 250 visitors per year.
