The Mar Menor is a saltwater lagoon, cut off from the Mediterranean by the thin strip of La Manga. Because it is shallow it warms quickly, and because it is sheltered it is rarely rough.
For a holiday with children, this is the main point. The water off Los Alcázares is knee-deep for a long way out. There are beaches with palapas, a wooden pier, and room to spread out.
Bring a book or a paddleboard, and not much else.
