Laguna del Retamar

Laguna del Retamar is a seasonal saline lagoon in the municipality of Pedro Muñoz, in the province of Ciudad Real, Castile-La Mancha. It forms part of the Pedro Muñoz lagoon complex, together with the Laguna de Vega (also called Laguna del Pueblo) and the Laguna de Navalafuente. The whole complex sits within the Záncara river basin, a tributary of the Guadiana, in an area known as La Mancha Húmeda — the "wet Mancha," a scattering of inland wetlands set against the otherwise dry, vine-covered plains of the region.

What should you know before visiting?

Retamar covers roughly 90 hectares, though its appearance changes dramatically through the year. It's an endorheic, strongly seasonal lagoon: during dry spells it can dry out completely, leaving behind a cracked, salt-crusted basin. Water levels depend almost entirely on rainfall, so the best time to see an actual sheet of water is winter and early spring, right after the rainy season.

The Pedro Muñoz lagoon complex has been under protection for decades. The Vega lagoon was designated a wildlife refuge back in 1988, the whole area gained Special Protection Area for Birds (ZEPA) status the following year, and in 1993 it was listed as a wetland of international importance under the Ramsar Convention. The nature reserve itself was formally established in 2002.

What will you see there?

Retamar's landscape differs from a typical freshwater lake. Continental saline grasslands dominate, along with halophilic vegetation — plants adapted to salty soil, including succulents that form a distinctive silvery carpet along the shoreline. This is a habitat of real ecological significance, protected at European level as a priority habitat type.

The lagoon and its surroundings are an important stopover for waterbirds and waders, especially during seasonal migration. The dry, salt-flat plain and the scrub around it stand in sharp contrast to the flat farmland typical of La Mancha, making it a rewarding stop for birdwatchers and landscape photographers alike.

How do you get there?

Laguna del Retamar lies within the municipality of Pedro Muñoz, a small town in Ciudad Real province, well connected to the rest of the La Mancha region. The easiest way to visit the lagoon complex is as a short trip out from Pedro Muñoz itself, following the local tracks and access roads that link the different lagoons. Bring water and sun protection — the terrain is open, with virtually no shade.

When is the best time to come?

Autumn, winter and early spring are the best seasons to visit, when water levels are highest and the lagoon looks its best, drawing in waterbirds. In summer, especially during dry years, the water can disappear entirely, and the saline vegetation and geological character of the terrain take center stage instead.
