The shore
Warm, shallow and calm — the Mar Menor has some of the easiest, safest swimming on the Spanish coast. Compare lagoon and Mediterranean beaches, find the best shore for your day, and read the detail on facilities, parking and access.
The Mar Menor offers two very different coastlines in one place. Use these guides to find the right beach for families, calm water, quiet, sunsets or water sports.
The Mar Menor is a sheltered saltwater lagoon, separated from the open Mediterranean by the slender La Manga strip. Lagoon beaches (Villananitos, Los Alcázares, Santiago de la Ribera, Los Nietos, Cavanna) are shallow, warm and almost always calm — ideal for families and beginners. Mediterranean beaches (El Mojón, the outer side of La Manga, Cabo de Palos coves) are deeper, cooler and livelier, with waves and occasional currents. Knowing which sea you are on is the first step to choosing the right beach.
For small children, Villananitos is the calmest and shallowest — you can walk out tens of metres and still be waist-deep. Los Alcázares adds the convenience of a flat promenade, cafés and accessible points. Both warm up quickly and stay gentle even when the Mediterranean is choppy.
The northern lagoon shore (Villananitos, Los Alcázares, Santiago de la Ribera) offers the still, mirror-flat water the Mar Menor is famous for. The lagoon is barely tidal and protected from wind chop on its leeward side, so these beaches stay swimmable when exposed coasts are not.
Los Nietos on the southern shore is the quietest of the main beaches — long, local and uncrowded, with room to spread out even in summer. El Mojón, beside the channel and the salt flats, is the most natural and least developed, with dunes and big skies rather than beach clubs.
The southern and western shores face the evening sun. Los Nietos and the La Manga lagoon side (Cavanna) give wide, open sunsets over the water, while El Mojón offers dramatic skies over the salt flats. Arrive early in peak season to claim a spot with a clear western view.
The reliable thermal wind on the La Manga strip makes Cavanna the natural hub for windsurfing, kitesurfing and paddleboarding, with schools and hire in season. Cabo de Palos is the base for diving and snorkelling the marine reserve. The flat lagoon works for learning almost anywhere on the northern shore.
San Pedro del Pinatar gives you Villananitos and El Mojón; Los Alcázares has its long town beach; Santiago de la Ribera offers its elegant sailing-quarter shore; Los Nietos serves the southern shore; La Manga offers Cavanna and the two-sea choice; Cabo de Palos gives rocky coves and the marine reserve. See each beach card below for detail.
Lifeguard cover, toilets, showers, accessible boardwalks and amphibious chairs operate mainly in the summer season and vary by beach. The resort beaches (Los Alcázares, Santiago de la Ribera, Cavanna) have the most services; the natural beaches (Los Nietos, El Mojón) have few. Parking is free but tight in peak summer — arrive early. Each beach card below lists the facilities, parking and nearby food we have been able to confirm, with a last-checked date. Always verify with the local tourist office before travelling.

Los Nietos (Cartagena)
A long, quiet stretch on the southern shore — a local favourite with plenty of space to spread out.
La Manga del Mar Menor
A lively La Manga lagoon beach where the wind and shallow water make it a hub for water sports.
San Pedro del Pinatar
A natural, open-Mediterranean beach near the channel that links the lagoon to the sea.
Beach facilities, lifeguard cover, accessible points, parking and access conditions change by season. The last-checked date shows when we last updated a field — confirm current details with the local tourist office before travelling.

Yes. The flat lagoon works for learning almost anywhere on the northern shore, and Cavanna on La Manga is the hub for windsurfing, kitesurfing and paddleboarding, with schools and hire in season.
Yes — El Mojón, the outer side of La Manga and the Cabo de Palos coves are on the open Mediterranean. They are deeper, cooler and livelier than the lagoon.
Outside peak summer, parking and space are much easier. Los Nietos and El Mojón are the quietest of the main beaches, and in peak season it pays to arrive early.
Villananitos has an accessible boardwalk and Los Alcázares has accessible points. Accessible boardwalks and amphibious chairs operate mainly in summer and vary by beach, so confirm with the local tourist office before travelling.
