San Pedro del Pinatar: salt, dunes and the lagoon edge

San Pedro del Pinatar occupies the northern tip of the Mar Menor, where the lagoon, the open Mediterranean and a working saltworks meet along a few kilometres of low coast. The town separated from Murcia in 1836 and took its name from the pine woods that once covered the sandy ground. Salt, fishing and more recently tourism have all depended on the same shallow water, and the balance between them is the subject most worth understanding here.

A protected saltscape

The Salinas y Arenales de San Pedro del Pinatar cover about 856 hectares between the Mar Menor and the sea. The Región de Murcia gave the area protected status in 1985 and declared it a regional park under regional law in 1992. It has been on the Ramsar list of wetlands of international importance since 1994 and is a Special Protection Area for birds. Salt has been gathered here since antiquity and the ponds are still worked commercially, so the park is a managed industrial landscape rather than an untouched reserve.

The saltworks themselves create the habitat. Sea water is drawn through a sequence of shallow evaporation pans that concentrate the brine and leave beds of salt, and the same still water supports the brine shrimp and invertebrates that feed large numbers of waders, terns and flamingos. Wooden pumping mills once moved water between the pans. The surviving Molino de Quintín, built in the early twentieth century, is the landmark most walkers photograph.

Dunes, mud and the lagoon

Between the ponds and the Mediterranean lies a belt of white dunes held together by marram grass and stands of pine and juniper. A boardwalk crosses this strip to the beach at Playa de la Llana, which keeps the low even profile the whole northern shore shares. On the lagoon side, shallow warm water and dark sediment have long drawn people to coat themselves in the mud before rinsing in the salt pools. The practice is popular and the muds are studied, but it takes place in a protected wetland where trampling and extraction cause damage, so the park authority marks where it is allowed and asks visitors to keep to those points.

The encañizadas and the fishing tradition

The channels that connect the Mar Menor to the sea, the golas, have been fished for centuries using the encañizadas, screens of cane set across the flow to trap fish moving between the two bodies of water. The technique is recorded from the medieval period and is tied to the same families and boats that worked out of Lo Pagán. Commercial fishing has declined as the lagoon's condition has worsened, and the encañizadas now sit at the southern edge of the protected area as much heritage as livelihood.

Lo Pagán and the town

The built town has two parts. The old centre stands slightly inland around the church of San Pedro Apóstol, while Lo Pagán runs along the lagoon shore with a promenade, a small marina and the mud-bath beaches. The distinction matters for visitors: the seafront is busy in summer and quiet out of season, and the park entrances at the end of Lo Pagán are the usual starting points for the salt-pan walks and the cycle paths.

Visiting with the lagoon in mind

The Mar Menor as a whole has suffered severe episodes of oxygen loss and fish deaths driven by nutrients washing off the surrounding farmland, and in 2022 the Spanish parliament gave the lagoon its own legal personhood in an attempt to force recovery. San Pedro's salt park is one of the healthier corners, but it is not separate from that story. Stay on the boardwalks and marked tracks, follow the current guidance on the muds and check the park visitor centre for closures. The wider lagoon is covered in the guide to La Manga and the Mar Menor, and the neighbouring shore around the air academy in the guide to San Javier.

Reviewed in September 2026 using the Ayuntamiento de San Pedro del Pinatar's regional park pages for the 856 hectares, the 1985 protection, the 1992 regional park declaration, the Ramsar listing and the Molino de Quintín, the Región de Murcia environmental information service for the park's boundaries and bird designations, regional and municipal history pages for the 1836 separation from Murcia and the origin of the name, and Región de Murcia cultural material for the encañizadas fishing tradition. The account of the Mar Menor's nutrient crisis and the 2022 law granting the lagoon legal personhood follows the published text of Ley 19/2022 in the Boletín Oficial del Estado. Access rules for the dunes, salt pans and mud baths change with the season and the state of the wetland, so confirm them with the park before visiting.
