The Marble Mountains, known locally as Ngu Hanh Son, consist of five limestone and marble hills named after the five elements: Metal, Wood, Water, Fire, and Earth. The site features a dense network of natural caves, grottoes, and tunnels historically used as shelters by local villagers and revolutionary forces. Several Buddhist and Taoist temples are integrated into the mountain structures, most notably within Huyen Khong Cave. Visitors can access the summit of Thuy Son (Water Mountain) via stone stairs or a glass elevator for elevated views of the coastline. The site is a significant source of traditional marble sculptures produced by local artisans in the surrounding villages. Vegetation is sparse on the rock faces, but the interior cave microclimates support specialized flora. The site is currently open to the public for tourism and religious practice.
