A spa-resort complex in the Deoksan hot-spring district operated by Resom Spa & Resort, combining Splas Theme Spa (Korea's largest indoor spa-water park), outdoor germanium-mineral hot-spring pools, and a 406-key hotel. The Deoksan hot-spring source has been bathed in for roughly six centuries and is officially designated a national therapeutic hot spring; its high-silica chemistry is comparable to Iceland's Blue Lagoon. Day visitors can buy spa-only tickets without staying overnight.
