Doblemar is the big beachfront machine of La Manga, sitting right on the calm Mar Menor with its own stretch of shallow, warm lagoon. The Astro mini club keeps four to twelve year olds busy morning and afternoon, there is a children's pool alongside the main ones, and the whole place is geared to families who want to step out of their room and be on gentle sand in a minute. It is large and can feel busy, but for toddler-safe swimming with everything on tap, it delivers.
Our verdict
If you want the reassurance of shallow, calm water a few steps from a big all-in resort, Doblemar is La Manga's most complete family option on the lagoon.
The rooms
The biggest resort in La Manga, with plenty of family rooms, many looking straight over the lagoon. Rooms are comfortable and practical rather than boutique, and half-board or all-inclusive boards make it an easy, budget-friendly base for a week with young children.

525 Hotel
A smart, modern four-star in the heart of Los Alcázares with well-appointed rooms, some with connecting options for families. A short walk brings you to the wide, shallow Los Narejos beach, one of the gentlest stretches on the whole lagoon for small children.

Hotel Izán Cavanna
Simple, bright rooms, most with a balcony and a view over the lagoon or the pool. Family rooms sleep up to four, and the hotel sits on the narrow strip of land with the calm Mar Menor on one side and the open sea on the other, so you are never more than a couple of minutes from shallow water.

La Manga Club
A vast resort estate above the Mar Menor with hotel rooms, apartments and villas, many with their own kitchen and pool. Family accommodation is generous and the self-catering options suit longer stays, though the layout is spread out and a car or the resort shuttle helps.
