The Vietnam National Administration of Tourism has supported the installation of a cable car system near Son Doong Cave, a tourism attraction, in central Quang Binh province,local online newspaper VnExpress reported on Monday.
Vietnam's tourism watchdog's chief Nguyen Van Tuan said the system, which will connect Son Doong and Phong Nha caves in the Phong Nha-Ke Bang National Park, will help lure more visitors.
Many experts assumed that the planned cable car system will negatively affect the environment.
Son Doong Cave is more than 200 meters wide, 150 meters high, and approximately nine km long.
