The Costa Blanca is known for its golden beaches and azure waters, but just inland, there is a natural phenomenon that provides a one-of-a-kind and truly therapeutic experience: Torrevieja and La Mata’s stunning pink salt lakes. More than just a beautiful sight, these vibrant lagoons are thought to have incredible health benefits, making them a must-see for anyone looking for a different type of relaxation.
The Science Behind the Pink: Nature’s Unique Palette
So, what gives these lakes their vibrant bubblegum hue? It’s not magic but rather a fascinating natural phenomenon! The vibrant pink colour comes from a unique combination of microscopic algae and haloarchaea, a type of bacteria. These thrive in the extremely high salinity of the water, and microorganisms produce carotenoids, pigments similar to those found in carrots, which give the lakes their distinctive and photogenic colour. These lakes contain so much salt that they rival the Dead Sea.

Nature’s Spa: The Healing Properties
For centuries, the locals have intuitively understood the therapeutic power of these lakes, and many visitors now come specifically to experience their purported healing properties. The high concentration of salt, minerals such as magnesium, potassium, and calcium, as well as the unique mud found on the lakebeds, are thought to provide a variety of benefits:
- Skin health: Mineral-rich mud is frequently applied to the skin, serving as a natural exfoliant and detoxifier. Many people report improvements in conditions such as psoriasis, eczema, and acne.
- Joint and Muscle Relief: Soaking in warm, buoyant, salty water is said to alleviate arthritis, rheumatic pain, and general muscle aches. The high salinity provided weightlessness, which reduced pressure on joints.
- Respiratory Benefits: The air around the lakes is naturally enriched with beneficial mineral salts, which can be especially beneficial for people with respiratory conditions such as asthma and bronchitis. The World Health Organisation has even designated the Torreveiaja region as one of the healthiest places to live due to its microclimate.

The Visitor Experience: Floating and Mud Baths
Visiting the pink lakes provides an unparalleled sensory experience. You can wade into the shallow, warm water and instantly feel the incredible buoyancy, making it easy to float. The sensation is similar to floating in the Dead Sea.
Many visitors enjoy gathering mineral-rich clay from the lakebed, applying it to their skin, and letting it dry in the sun before washing it off in the lake. Remember to bring plenty of water to thoroughly rinse off after leaving the lake, as salt residue can be quite strong.
Accessing the Pink Lakes (and Important Tips)
While the lakes are a natural attraction, visitors must be responsible and stay in designated areas. While there is no official “spa facility,” many people visit the lakes from various locations along their perimeter.
Important Tips for Your Visit:
- Look for designated areas: While the lakes are vast, certain areas are more easily and safely accessible. Locals can often direct you to popular entry points. Avoid private property.
- Prepare: The lake can be muddy, so wear old swimsuits, water shoes or flip-flops that you don’t mind getting dirty.
- Bring water for rinsing: This is essential! Bring a large bottle of fresh water to rinse off the salty residue on your skin after your dip.
- Protect your eyes: The salt content is extremely high; avoid getting water into your eyes.
- Sun protection: Even during the cooler months, the Costa Blanca’s sun is strong. Bring sunscreen, a hat, and sunglasses.
- Leave your valuables at home. As with any natural, informal attraction, it is best to limit what you bring with you.
- Respect the environment: These are natural wonders that are part of a delicate ecosystem and a vital salt production sector. Take all of your trash with you and avoid disturbing wildlife.
