Travel Trance's video: Biggest Buddha Statue Inside Cave Marble Mountains Da Nang I Rented a Bike In Da Nang

(From Wiki): Marble Mountains is a cluster of five marble and limestone hills located in Ngũ Hành Sơn District, south of Da Nang city in Vietnam. The five mountains are named after the five elements: Kim (metal), Thuy (water), Moc (wood), Hoa (fire), and Tho (earth). All of the mountains have cave entrances and numerous tunnels, and it is possible to climb to the summit of Mount Thuy. Several Buddhist sanctuaries can also be found within the mountains, making this a tourist destination. The area is known for stone sculpture making and stone-cutting crafts. Direct rock extraction from the mountains was banned recently. Materials are now being transported from quarries in Quảng Nam Province. The mountains were very near the American Marble Mountain Air Facility during the Vietnam War. According to William Broyles, Jr., the Marble Mountains contained a hospital for the Vietcong, probably within earshot of the American airfield and Da Nang Beach (which bordered the airfield on the side opposite the mountains). He describes the enemy as having been so "certain of our ignorance that he had hidden his hospital in plain sight"
