Termas de Ahuachapán, in western El Salvador's volcanic heartland, taps sulfurous water at 42°C. An indoor bath and an outdoor rotenburo-style pool make up the facility.
Insider tip — Termas de Ahuachapan tap the powerful geothermal field of the same name, one of the most productive in Central America and the source of El Salvador's first geothermal power plant. The intensely sulfurous springs emerge near the famous Los Ausoles boiling mud pools and steam fumaroles, making the geothermal landscape itself a spectacle. Soaking in the bathing pools here is a genuine encounter with the volcanic energy underpinning this corner of the Pacific Ring of Fire. The nearby Tacuba hiking trails through cloud forest complete an adventurous visit.
