Located at the northern end of the Mar Menor, its name comes from a small church the fishermen dedicated to San Pedro in an area of pine trees. With its agricultural and fishing character, it has busy tourist activity in Lo Pagán, where its mud baths are particularly famous and good for your health.

Its history stretches back to the Roman era, from which remains of houses have been discovered and during which the exploitation of the salt flats of Coterillo was begun; salt flats which are still working today. These wetlands were formed with the dunes and the beach of La Llana, which is the oldest of the Regional parks of Murcia, and which is a refuge for over one hundred bird species, among which the flamingo is worthy of particular mention. besides the park, where it is possible to observe the fauna and flora as well as unique constructions such as the salt mills, it is also worth paying a visit to stately homes such as the Casa del Reloj, which was home to the death of Emilio Castelar, the Palace of Villar de Felices, the Ethnographical Archaeological Museum and the Fish Market.
