Termalitas del Arenal Hot Springs

Termalitas del Arenal Hot Springs in La Fortuna, Alajuela Province, Costa Rica, is an intimate thermal facility drawing bicarbonate-rich volcanic water from the Arenal geothermal system into small, artfully designed pools embedded within a tropical garden at the foot of the volcano. The emphasis is on the quality of the natural geothermal water and the authenticity of the tropical setting rather than on resort amenities, attracting visitors who prioritise genuine mineral bathing in a natural environment over entertainment infrastructure. The surrounding jungle, with its extraordinary concentrations of hummingbirds, morpho butterflies, and tropical flora, creates a living backdrop that makes every visit to Termalitas del Arenal a simultaneously thermal and ecological experience.
