Thermal baths and outdoor hot springs in Spain: year-round wellness

none

In Spain, outdoor thermal tourism can be enjoyed at any time of year and in some of the country’s most stunning locations. Immersing yourself in the thermal baths, springs and natural pools scattered throughout the region is a direct invitation to tranquillity and well-being. From complete thermal spa complexes fed by natural springs to freely accessible natural pools tucked away amongst mountains, in forests or on river banks; each location offers a unique experience. The contrast between the hot water gushing from deep within the earth and the temperature of the surroundings, along with the plant life and the silence that usually accompanies it, creates a sensation that is hard to forget. It’s a different — and deeply relaxing — way to discover Spain, connecting with nature and with the unhurried pace that invites you to slow down. We’d like to take you on a route of some of the country’s thermal baths and hot springs so you can discover the therapeutic benefits of these waters and treat yourself to a moment of wellness in the very heart of nature.

Natural pools and waterholes to cool off in summer

As well as these places, Spain has other natural spots for swimming, such as rivers, gorges, springs and unique geological formations with ambient-temperature water. All of them come highly recommended, especially during the warmer months of the year. Some suggestions are: Las Chorreras del Cabriel (Cuenca) - What makes it special? In the province of Cuenca, the River Cabriel has carved out a spectacular landscape as it flows through the towns of Enguídanos and Víllora: waterfalls, cascades and turquoise pools nestled amongst rocks and lush vegetation. This place is ideal for hiking, swimming and observing its biodiversity. La Pesquera (Teruel) - What makes it special? In the vicinity of the village of Beceite there are several natural pools, where the blue hues contrast with the colour of the limestone and the surrounding Mediterranean vegetation. Charco Azul (in El Hierro) - What makes it special? What makes this spot on the Canary Island of El Hierro, comprising two small natural pools, is its volcanic origin. The surface remains calm while the waves crash just a few metres away, creating a fascinating contrast.
