Riyuegu Hotsprings is a purpose-built hot spring attraction in Fujian, developed around a naturally occurring mineral source just off Xiamen Island. It opened in November 2003, at a point when attraction-style hot spring parks were still emerging in China, and was conceived from the start as a place where hot springs form the foundation of a whole visit rather than a single treatment. The springs themselves were known here long before that. A stone plaque found on the site records a visit made in 1567 by a court official during the Ming dynasty. The recognition of these waters runs centuries deeper than the attraction built on them.

That source still defines the character of the place. Rather than enclosing pools indoors, Riyuegu was designed to set hot springs within landscape, creating open-air soaking environments supported by gardens, pathways, and sheltered spaces. The property covers 200,000 square metres in all, of which the hot spring park spans approximately 65,000, holding dozens of pools alongside massage rooms, swimming and activity zones, and dining, with accommodation on site. Scale of that kind was never meant for a short stop. The layout suits several hours, a full day, or a longer stay, and suits couples, families, and multi-generational groups alike; guests may spend the day soaking, or move between pools, treatments, and lighter activities within the same grounds.

Riyuegu Hotsprings holds a Five-Star Hot Spring rating, China's top tier, awarded against standards covering water quality, facilities, service, environment, and management. It also holds National AAAA Tourist Attraction status. Facilities have expanded over more than two decades, but the purpose has not changed: a place where the springs are the heart of the visit. More than 8 million guests have been served since 2003.
