Termas de Santa Teresa is located in Santa Teresa, Usulután Department, El Salvador. This sulfurous spring, with water reaching 42°C, feeds an outdoor pool where wild bathing is practiced.
Insider tip — Termas de Santa Teresa tap the volcanic plumbing of El Salvador's Pacific volcanic arc, where sulfurous water at 42°C surfaces amid tropical dry forest and sugarcane fields in the Usulutan lowlands. The springs are frequented by local families on weekends, maintaining an authentic, unhurried atmosphere far from the resort tourism of the Pacific coast. The sulfur content is prized by bathers for its reputed benefits against skin conditions and joint pain. Combine a visit with exploration of the nearby Laguna de Olomega, a freshwater lake rich in aquatic birds just a short drive away.
