There are numerous spas and treatment centres in the region where holiday makers can discover the benefits of the Mar Menor mud for themselves.
However, many tourists can do so simply by bathing in the warm sediment, which is thought to be particularly useful in treating skin conditions.
Its healing properties are said to be down to the climatic conditions of the region, which enjoys long hours of sunshine and has high levels of salinity.
Even paddling in the waters of Mar Menor can be good for the health of the skin thanks to its high salt content.
And since the temperature of the lagoon is warmer than the rest of the waters in the Mediterranean, it will also be very pleasant.
Holiday makers eager to try out some Mar Menor mud treatments could rent Costa Calida villas at the Mar Menor Golf Resort. Its spa won the best spa award in 2007.
It is also home to a wide range of sporting facilities, including a nine-hole golf course, a gym and tennis courts, so visitors can keep fit during their stay.
