Baldi Termae Arenal

Baldi Termae Arenal is a lavish outdoor thermal resort at the foot of Arenal Volcano in the La Fortuna district of Alajuela Province, Costa Rica — one of the most visited destinations in Central America, where the perfectly conical Arenal Volcano provides a dramatic backdrop of geological power to the resort's 25 graduated thermal pools maintained at temperatures between 28°C and 67°C. The naturally warm calcium-rich geothermal waters emerge from the volcanic geology of the Arenal volcanic field, directly heated by the same magmatic system that made Arenal one of the world's most continuously active volcanoes from 1968 until its current period of quiet since 2010. Baldi's extraordinary pool complex, descending in cascading terraces down the volcanic hillside with panoramic views of the volcano and Lake Arenal, is one of Central America's most spectacular thermal bathing landscapes, illuminated at night when the pool system becomes a glowing LED spectacle against the dark volcanic sky. The La Fortuna area's biodiversity — cloud forest, hanging bridges, chocolate tours, waterfall rappelling, and some of Costa Rica's finest wildlife including poison dart frogs and toucans — surrounds the thermal resort with world-class ecotourism experiences.
