This tour takes us close to one of the most important coastal wetlands for water bird reproduction in Europe. A priority zone for nesting, rest and feeding of great ornithological interest.

Along the trail we will find two bird observatories, one oriented at the estuary of the old salt marsh, frequented by, among others, flamingos, avocets, herons and little terns, and the other oriented at the River Arillo, from where we can watch at low tide a multitude of small waders like dunlins and Kentish plovers.

It is also a reproduction and hatching area for an extensive number of fish and invertebrate species.

The salt marsh industry was one of the Bay’s most emblematic economic activities and this tour allows us to distinguish the different parts of a traditional salt marsh: the estuary, pickle ponds or crystallisers.

Along our walk we will see remains of old buildings such as the tide mill of the River Arillo, included in the General Catalogue of Andalusian Historical Legacy.
