Termos del Río is a natural hot spring resort in El Salvador drawing on geothermal water from the country's volcanically active substrate to offer a riverside bathing experience in the tropical landscape of one of Central America's most densely populated nations. El Salvador's thermal springs, concentrated in the western volcanic highlands near the border with Guatemala, reflect the intense geothermal activity of the Central American volcanic arc. The country's rich pre-Columbian Pipil cultural heritage, vibrant contemporary arts scene, and the dramatic coffee landscape of the Apaneca-Ilamatepec mountains provide a culturally engaging context for exploring the country's natural thermal resources.

Insider tip — Termos del Rio is fed by the same geothermal system that powers El Salvador's Ahuachapan geothermal power plant, one of Central America's earliest renewable energy facilities. The thermal waters reach the surface along river banks lined with tropical vegetation in the western coffee highlands. The site offers a rare glimpse into how geothermal energy and traditional bathing culture coexist in the same geological zone.
