In Costa Rica, there are hot springs of different temperatures, flow volumes and mineral content that can be found in the regions around the Arenal, Irazu, Miravalles and Rincon de la Vieja Volcanos. But the perfect combination of volume, temperature and mineral content (low sulfur content to prevent strong odors) that is present in Tabacon Grand Spa Thermal Resort is unique in Costa Rica and worldwide. Hot springs are considered a natural expression of Earth’s inherent energy. Geologically they are found near several volcanoes throughout Costa Rica, Thermal natural springs are 97% rain-based and 3% magma-based. Rainwater enters the earth through fissures on the surface and is then heated by magma found in the earth’s core. Once heated, the waters rise to surface, taking with them minerals found in the earth’s rocky stratus.
