Bang Mineral Hot Spring

Bang Mineral Hot Spring is a natural mineral hot spring located in Kim Thuy Commune, Le Thuy District, Quang Tri Province (formerly Quang Binh), about 45 km southwest of Dong Hoi. It is noted as one of Vietnam's hottest hot springs, with source water reaching around 105°C. The site has been developed into Bang Onsen Resort offering onsen-style baths, mineral pools and spa services amid forested hills near the Kien Giang River headwaters.

Visitors can expect a developed hot spring resort set in a forested valley with natural gushing hot water, Japanese-style onsen pools, mineral bathing areas, mud baths and spa facilities. The central spring area features steaming vents and pools where water emerges at very high temperature, while bathing is done in regulated pools with cooled mineral water. Surroundings include hills, streams and resort buildings with restaurants, changing areas and landscaped gardens for relaxation and sightseeing.

Bang Mineral Hot Spring has long been known locally for its exceptionally hot mineral water and was later surveyed for its geothermal and therapeutic properties. The spring has been developed in recent years into a resort complex with Japanese onsen cooperation, becoming a notable health tourism site for Quang Binh, now Quang Tri Province.

The spring is valued locally for its mineral water believed to have health and wellness benefits and is now presented as a wellness tourism destination combining Vietnamese natural resources with Japanese onsen bathing culture.
