Laguna de la Veguilla

Laguna de la Veguilla is a shallow lagoon on the outskirts of Alcázar de San Juan, in the province of Ciudad Real, Castilla-La Mancha. It forms part of the Complejo Lagunar de Alcázar de San Juan, a chain of three consecutive wetlands stretching across roughly five kilometres between Alcázar de San Juan and Villafranca de los Caballeros, right in the heart of the historic Mancha Húmeda region.

Where is it located?

Of the three lagoons making up the complex, La Veguilla sits closest to the town of Alcázar de San Juan, which makes it the most accessible and most frequently visited spot in the whole area. It is surrounded by a classic La Mancha farming landscape of vineyards, olive groves and irrigated fields, so the wetland ecosystem blends directly into agricultural countryside. The combined lagoon area covers around 136 hectares.

The entire lagoon complex is protected under the European Natura 2000 network, holding status as a Site of Community Importance and a Special Protection Area for birds. That conservation ranking is exactly what draws birdwatchers here from across Spain and beyond.

What will you see?

What sets La Veguilla apart from its neighbouring lagoons is that it holds water all year round. This is because it receives treated water discharged from the nearby Alcázar de San Juan wastewater treatment plant, so unlike the other, seasonal lagoons in the complex, La Veguilla does not dry out even during the hottest summer months. That makes it the most reliable spot in the area for watching waterbirds in any season.

The star attraction is the greater flamingo, present at the lagoon year-round and occasionally joined by the much rarer lesser flamingo. The reedbeds and open water also support breeding white-headed ducks and purple swamphens, and the lagoon is considered one of the better places locally to spot the marbled teal, a duck species that is seriously threatened across Europe. To support visitors who come specifically to watch birds, the local council recently opened a new, accessible birdwatching platform designed to blend into the surrounding landscape.

When to visit?

Because the water level stays constant, La Veguilla can be visited at almost any time of year, unlike the seasonal lagoons nearby that often dry up in summer. Early morning offers the best birdwatching conditions, when foot traffic is lowest and birds are most active. Spring and autumn migration periods tend to bring the widest variety of species, while summer in La Mancha can get very hot, so it's worth timing a visit for the cooler hours of the day.

How to get there?

La Veguilla lies along a signposted walking and cycling route connecting the lagoon to the area around Villafranca de los Caballeros, known locally as the Ruta La Veguilla and promoted by the Alcázar de San Juan town council. Given its proximity to the town centre, it's an easy trip by car, bike, or on foot for anyone staying in Alcázar de San Juan itself. Bring binoculars — this is a spot built around quiet, patient birdwatching rather than tourist infrastructure.
