Riyuegu Hotsprings is a hot spring park and hotel in Haicang District, Xiamen, at the foot of Tianzhu Mountain and about 30 minutes from the city centre. Open since 2003, it is built around a natural mineral hot spring source, with dozens of open-air pools set among landscaped gardens, alongside swimming pools, dining, and 115 guest rooms and suites. Riyuegu holds National AAAA Tourist Attraction status and China's Five-Star Hot Spring rating.

The springs were valued here long before the park was built. More than 400 years ago, during the Ming dynasty, a court official named Ding Yizhong came to see them for himself and wrote the Wenquan Ming, an inscription describing this “heavenly gift” as one set neither in the city nor in the mountains, but where ordinary people could reach it. The stone plaque bearing his words was rediscovered in the 1980s, on the ground where Riyuegu now stands.
