Thermal getaways, hot water a short trip from home.

What are thermal getaways?

It is not a region but a type of trip: going to a place where water comes hot out of the ground and spending a day or a weekend there. Here are the ones that have a page on Geocalia: first those less than two hours from Spanish cities, then the great spas of Europe.

The same label covers very different things. There are open-air pools, beside a river, free or almost, where you bathe with just your swimsuit and a towel. There are public or municipal baths, with spring-water pools and entry by the hour. There are classic spa resorts, with mineral-medicinal water treatments and often a hotel. And there are hotel spas that heat ordinary water: they are pleasant, but they are not thermal. Before you book, check where the water comes from and at what temperature.

How do you choose a thermal destination?

First, by distance. If you only have one day, look for one less than an hour and a half from home: you arrive in the morning, bathe without hurrying and are back for dinner. With a weekend you can go further and add an old town or a walking route.

Then, by the type of bath. Free pools have no opening hours or ticket office, but no changing rooms either and, in high season, they fill up. Paid baths have showers, lockers and a limited bathing time, and some do not admit children or set a minimum age.

Finally, by temperature. Water at 25 °C, like at Montanejos, is for swimming in summer and is less tempting in January. Water at 35 or 38 °C is for sitting still, especially in cold weather. And the hottest springs, like the Font del Lleó in Caldes de Montbui, at 74 °C, are not to be touched: you watch them steam, and the water is cooled for the baths.

Where is there thermal water near home?

From Barcelona, Caldes de Montbui is about 35 minutes by car or bus: a fountain at 74 °C in the square, Roman baths and baths by the hour in the town. From Madrid, the AVE high-speed train gets you to Ourense in about two and a quarter hours; there are hot springs beside the Miño, some free and some paid, although the public pools are closed until spring 2027 because of the state of the river.

From Valencia and Castellón, Montanejos is an hour or an hour and a quarter away: the Fuente de los Baños comes out at 25 °C all year in the Mijares river, and in summer it has entry with limited capacity. From Murcia, the Archena spa, in the Ricote Valley, is half an hour away, with thermal pools at about 32 °C among lemon trees.

In the Pyrenees, the Tena Valley has the Panticosa Spa at 1,636 metres, at the head of its valley, and across the border Cauterets is a French spa town that also serves as a gateway to the Pyrenees National Park. Without a page yet are the free pools at Arnedillo, beside the Cidacos river, in La Rioja.

And the great spas of Europe?

Hungary is the country of baths. In Budapest, Széchenyi and Rudas combine with a city visit. About two and a quarter hours away, Hévíz has a natural thermal lake where you bathe outdoors all year, and Eger, two hours away, combines baths, a castle and wine cellars.

In Bohemia, Karlovy Vary and Mariánské Lázně are about two hours from Prague: colonnades with springs you drink from a cup, free, and paid pools or spas. Near Vienna, Baden bei Wien has sulphur baths a little over an hour away on the Badner Bahn tram from the Opera. In Belgium, Spa, the town that gave its name to all the others, is an hour and a half from Brussels. And in England, Bath is 1 h 20 by train from London: the Roman baths are only for looking at, and you bathe in a modern spa with water from the same spring.

When is hot water most enjoyable?

From October to April. In cold weather, an outdoor bath at 35 or 38 °C is the best part of the trip. In July and August the pools in the south of Spain and the hot baths are less appealing; then it is better to choose warm waters, like Montanejos, or go first thing and at dusk. Spas in central Europe open all year, although some buildings close for works: at Hévíz, the central lake building is closed until 21 March 2027.

How many days do you need?

For the nearby ones, one day is enough: two or three hours in the water, a walk and lunch. If you want to bathe at night, add one. For Budapest allow three or four nights; for Hévíz, Karlovy Vary or Baden, one or two.

What should you know before you go?

Book weekends and bank-holiday weekends: small baths have limited capacity and fill up. Bring a swimsuit, flip-flops and a towel. Check the minimum age if you are going with children, because Bath, Spa or some Budapest baths set one. At free pools there is no lifeguard or changing room, and the stones are slippery: bring water shoes. If you are going to a treatment spa for health reasons, check with your doctor first; Imserso also has a thermal-treatment programme for pensioners with places at Spanish spas.
