A geothermal spa is a wellness facility that utilizes natural hot springs heated by the Earth's internal heat. These spas often feature mineral-rich waters, which are believed to have therapeutic properties. Visitors can enjoy various treatments, including soaking in hot pools, massages, and skin therapies, all designed to promote relaxation and health. Geothermal spas are commonly found in regions with volcanic activity, such as Iceland and New Zealand. The warm waters are not only soothing but also environmentally friendly, as they harness renewable energy from the Earth. Many spas also offer additional amenities like saunas, steam rooms, and wellness programs.
