The therapeutic mud of the Mar Menor is formed by the sedimentation of minerals over hundreds of years, mixed with high-salinity water.
The Mar Menor is Europe's largest saltwater lagoon, and its hyper-saline nature creates unique buoyancy for bathers.
The area is a crucial habitat for the Greater Flamingo, which can often be spotted in the nearby salt flats during migration seasons.
The high concentration of magnesium and calcium in the mud is clinically studied for its potential to soothe chronic skin conditions like psoriasis.
The site operates without artificial heating; the mud temperature is entirely dependent on solar radiation and ambient air temperature.
Las Charcas in San Pedro del Pinatar is a designated area for open-air mud baths located within the Salinas y Arenales de San Pedro del Pinatar Regional Park. The site features shallow pools where visitors can coat their skin in mineral-rich sediment known for high concentrations of cations, anions, magnesium, calcium, and iodine. After applying the mud and allowing it to dry under the sun, visitors typically rinse off in the adjacent Mediterranean waters of the Mar Menor. This therapeutic ritual is a centuries-old local tradition utilized for its reported anti-inflammatory and skin-softening properties. The location is uniquely situated between the salt marshes and the inner lagoon, creating a specific micro-ecosystem. Wooden jetties provide entry points into the mud pools, allowing for controlled access to the sediment. The site is maintained as part of a protected natural space, requiring specific environmental considerations during usage.
From the wooden walkways looking out toward the salt pans, especially during the "golden hour" when the reflection on the water is pronounced.
Bring an old swimsuit you do not mind staining, as the mud can permanently discolor light-colored fabrics.
Apply the mud in a thin layer and wait for it to fully crack and dry in the sun before washing it off in the lagoon.
Bring flip-flops to navigate the wooden boardwalks and transition areas comfortably.
Do not attempt to scrape mud from the bottom of the salt evaporation ponds, as these are restricted, protected areas.
Accessible year-round, though mud quality and comfort are significantly lower during winter months.
Avoid applying mud to the eyes or open wounds; rinse thoroughly in the lagoon to keep the area clean for others.
