Marble Mountain, around 20 kilometres north of Hoi An and on the outskirts of Da Nang, stands in a cluster of five marble and limestone hills. The five mountains are named Kim (metal), Thuy (water), Moc (wood), Hoa (fire) and Tho (earth). The main mountain, Thuy Son, (with a puzzling modern designed elevator running up the side) is home to several Buddhist and Hindu grottoes. There is also a large Pagoda called Tam Thai, built in 1825. If you are looking for a good half -day activity, Marble Mountain is a great place to visit for the whole family. You can buy a ticket for the elevator at the entrance for $1.50 or choose to climb the 156 steps to the summit for just under $1. This can be a sweaty affair when the temperatures reach the mid-thirties but lovely at other times of the year. At the top you are rewarded with great view of the coastline and Danang City, and the opportunity to purchase and light incense sticks to place in the Buddhist sanctuaries. Marble Mountain offers many small hidden treasures, much more than the outside suggests. From small shrines and intimate caves, to grand ancient halls where the sunshine beams through small crevices. The caves stay at a comfortable 20C all year round which can be a welcome break from the summer heat. The area around Marble Mountain is also famous for its stone sculpture making. The statues are beautifully carved by master craftsman into various sized statues. If you can afford the extra baggage allowance one of the smaller pieces would make a great souvenir from your trip to Vietnam.
