About Pozas de Arnedillo
Pozas de Arnedillo, Spain is a set of three free natural thermal pools along the Cidacos River in the village of Arnedillo in La Rioja, approximately 60 kilometres southeast of Logrono. Source water emerges from the ground at 52 degrees Celsius (125 degrees Fahrenheit) and cools as it flows through the three stepped pools, reaching 35 to 40 degrees in the pool furthest from the source. The pools sit directly beside the Cidacos River, allowing bathers to alternate between warm thermal water and cool river water for contrast soaking. Logrono, the capital of the La Rioja wine region, is the nearest major city with full services.
These aguas termales have been used since Roman times, when they were valued for their medicinal properties. The water travels approximately 4,000 metres underground, filtering through sandstone that enriches it with minerals, then rises through limestone to emerge at the surface. The village of Arnedillo has arranged the pools with simple stone steps and a surrounding stone lounging area, plus a rustic shower. Access is free and the site is open 24 hours a day, 365 days a year.
Nestled between the Sierra de la Hez and Pena Isasa mountain ranges, the pools remain a relatively hidden gem among the hot springs in Spain.
Location & Access
Getting to Pozas de Arnedillo
Pozas de Arnedillo is reached via a short walk from the village centre of Arnedillo, located on the N-232 highway in southern La Rioja. The nearest parking is at the village swimming pools (ask for "las piscinas del pueblo"), from which a short, signed path leads down to the thermal pools beside the Cidacos River.
From Logrono, the drive takes approximately 1 hour via the A-12 and LR-115 south through Calahorra and then west to Arnedillo. From Zaragoza, the drive is approximately 2 hours west via the AP-68 and A-12. From Madrid, the drive is approximately 3.5 hours northeast via the A-2 and A-12. The village is small and signage is limited, so GPS navigation is helpful.
La Rioja Thermal Region
La Rioja has a long history of thermal bathing dating back to Roman settlement. For visitors seeking hot springs near Logrono, Pozas de Arnedillo is the most famous and most accessible wild option. The Balneario de Arnedillo (a historic paid resort spa in the same village, drawing from related geothermal sources) is a short walk from the pools and offers developed facilities and treatments. Fitero Hot Springs, across the border in Navarra, is another regional thermal destination approximately 45 minutes southeast.
Suitability & Accessibility
Who Should Visit Pozas de Arnedillo
Pozas de Arnedillo suits travellers, families, and solo visitors seeking a free, authentic natural thermal bathing experience in rural Spain. The three stepped pools at descending temperatures (from very hot near the source to a comfortable 35 to 40 degrees Celsius at the furthest pool) allow bathers to find their preferred heat. The ability to dip into the cold Cidacos River between hot soaks creates a traditional thermal contrast circuit. Clothing is optional, and nudism is permitted at the pools.
The site can become very crowded, especially on summer weekends and bank holidays. Early morning, late evening, and winter months offer quieter conditions. Winter soaking is particularly popular at these aguas termales, as the warm water contrasts with cold ambient air for a cosy escape. Hotel Palacios Rioja in nearby Alfaro and smaller rural lodgings in Arnedillo provide convenient overnight options.
Accessibility at Pozas de Arnedillo
A short path leads from the village parking area down to the pools, with stone steps into the water. The site is not wheelchair accessible due to the terrain. Those exploring free hot springs Spain offers with easier access or more facilities should visit the paid Balneario de Arnedillo (same village, developed thermal spa with treatments and massage services, open year-round to day visitors and overnight guests alike).
Safety & Etiquette
Pozas de Arnedillo Safety Tips
Pozas de Arnedillo is generally safe for soaking, though source water emerges at a very hot 52 degrees Celsius and bathers should always test each pool before entering, as no lifeguards or staff are on duty at this free public site. The first pool closest to the source is the hottest. The downstream pools at 35 to 40 degrees are comfortable for extended soaking. Supervise children at all times near the water, especially near the hotter pools.
Stay hydrated. Limit sessions in the hotter pools to avoid overheating. Alternate with cold dips in the Cidacos River to extend soaking time. The river current is usually calm but can rise after heavy rain.
Crowds and Etiquette
The pools are a shared public space and respect for other bathers is essential. Share the pools and the shower. Pack out all trash. Dogs are generally allowed in the parking area and surrounding paths on leash but should not enter the water. Nudism is permitted but not required. Follow the lead of other bathers if unsure.
Climate and Travel Notes
La Rioja has a continental Mediterranean climate with hot summers and cold winters. Summer daytime temperatures can exceed 30 degrees Celsius, making night-time soaking preferable. Winter temperatures can drop near freezing, making the warm pools especially appealing. The surrounding Sierra de la Hez and Pena Isasa mountains offer hiking, cycling, and panoramic views of the Cidacos valley throughout the year, with the hills around Arnedillo offering gentle walking routes.
