Ngũ Hành Sơn - the Five Elements Mountains - is a cluster of five marble and limestone peaks rising from the coastal plain of Đà Nẵng's Ngũ Hành Sơn district, approximately 7km south of the city centre and midway between Đà Nẵng and Hội An. The name was given by Emperor Minh Mạng in 1837 (the 18th year of his reign), who named each peak after one of the five classical elements based on its natural shape and position: Kim (metal), Mộc (wood), Thủy (water), Hỏa (fire), and Thổ (earth). Of these, Thủy Sơn (Water Mountain) is the only peak open to the public and contains the site's main attractions.
A Sacred Site Since the Cham Era
The mountains have been a sacred site since the Cham civilisation, and the cave temples added by Vietnamese Buddhists and Nguyễn dynasty emperors layer over the earlier Cham sanctuaries.
Huyền Không and Other Caves
The site's defining experience is Huyền Không Cave - a natural limestone cavern where a section of ceiling collapsed centuries ago, creating an opening through which sunlight falls in long shafts onto the Buddhist altars below, most dramatically between 11 AM and 12 PM on clear days. Other notable caves within Thủy Sơn include Tàng Chơn, Vân Thông, and Linh Nham, each with a distinct character and Buddhist shrine.
