We find in Los Alcázares the most international beaches of the Mar Menor, full of bars and establishments to the taste of European tourists. Must visit is the Spa of the Incarnation built in 1904 and starting point of a tourist process on the beach of Manzanares. It is perhaps Los Narejos one of the beaches that has most evolved in this aspect along the Mar Menor. A nice walk leads you through all the beaches of the Alcázares from the port to the beach of La Hita, a protected natural space included in the Open Spaces and Mar Menor Islands.
The waters of the Mar Menor by their chemical characteristics acquire the category of medicinal. The high concentration of salts and iodos, the absence of waves, the shallow depth of its waters and, of course, its exceptional temperature both in summer and winter, form a unique set and make the Mar Menor the best therapeutic remedy. Analyzes of its waters show that ionic concentrations measured for some elements such as magnesium, calcium, sodium, bromine, iodine and fluoride are found in quantities much higher than those in the Mediterranean, so that thermal treatments with this type of saline waters and the application of sludge produce a toxic particle elimination, activation of the blood system and a muscular relaxation, well indicated for cases of stress, rheumatic diseases, sciatica, lumbago and all kinds of affections related to the skin and the joints.
The Mar Menor, besides being the largest open air spa, is considered one of the best regatta courses, where it is possible to practice all kinds of water sports throughout the year.
