Rio Negro Hot Springs is a natural geothermal destination in the Alajuela province of Costa Rica, situated in the volcanic highlands near the Miravalles volcano — one of the active volcanic centers of the Guanacaste Volcanic Range in northwestern Costa Rica. The bicarbonate mineral waters, heated by the volcanic activity of the Miravalles system, emerge through the lush tropical forest and are channeled into natural and developed pools that offer bathing in a setting of exceptional biodiversity and rainforest beauty. The area forms part of Costa Rica's rich network of volcanic hot spring destinations, and the combination of thermal waters, tropical nature, and the extraordinary ecological richness of the Costa Rican volcanic highlands creates a bathing experience of rare natural intensity. Rio Negro Hot Springs represents the finest expression of Costa Rica's geothermal abundance — where the volcanic energy of Central America's most biodiverse country rises directly into pools surrounded by primary rainforest.

Insider tip — Treat yourself to a thermal break at Rio Negro Hot Springs, where the bicarbonate water reaches 41°C.
