Details
Access
Coto de la Isleta is located west of the town of Chiclana de la Frontera. The entire space is open, there are no fences. There is only one gate at the entrance to the route, which has a pedestrian crossing. The car can be left next to the gate, parked next to a eucalyptus tree. Click on the P in the map for directions. The circular walk is about 4 km. The path can be muddy if it has rained recently, and is best at low tide or with the tide going out (see the link to the tides table below), as the path walls can sometimes be flooded with spring tides. From August to November, it is especially interesting because it is in the migratory corridor of Eurasian Spoonbill, which cross over the islet in large spectacular groups on their way to Africa. Also notable is the large concentration of Eurasian Curlew that come and go to eat at dusk in the surrounding marshes and that, in their autumn migration, also form large groups. On the island there are several Common Kingfisher and a good population of Magpie and Common Wood Pigeon. And on summer nights you can hear Red-necked Nightjar and Tawny Owl.
PLEASE NOTE: In July 2025 we received two comments (see below) that the path to the island had eroded in and was not passable anymore. Wellies are needed. Please leave a comment below if you visit this area and update us on the current situation.

Espagnol: Todo el espacio está abierto, no existen alambradas ni otros impedimentos. Solo hay una cancela a la entrada del recorrido, que tiene un paso habilitado para peatones. El coche se puede dejar junto a la cancela, aparcado al lado de un eucaliptal. El camino puede tener barro si ha llovido recientemente, y es mejor en bajamar o con la marea bajando, ya que los muros de los caminos a veces pueden estar inundados con las mareas vivas. De agosto a noviembre, es especialmente interesante por estar en el corredor migratorio de las Eurasian Spoonbill, que cruzan por encima de la isleta en grandes bandos espectaculares en su camino a África. También sobresale la gran concentración de Eurasian Curlew que entran y salen a comer al atardecer de las marimas aledañas y que, en paso posnupcial, también forman grandes bandos. En la isla hay varios Common Kingfisher y una buena población de Magpie y de Common Wood Pigeon. Y en las noches de verano se escuchan los Red-necked Nightjar y los Tawny Owl.
