The Odiel Marshes Nature Reserve is the second largest wetland in Huelva province after Doñana and the most important tidal wetland in Spain. This area was created by the silt of the rivers Odiel and Tinto and in this estuary we can find a paradise for the birdlife. This is a day out to the “Kingdom of the Tide” to look for waders, seabirds and other aquatic birds. By the road that connects some of the islands on the Odiel Marshes we can get to Anastasio Senra´s Visitors’ Centre and continue to have interesting sightings on the mudflats going south. Finally we go to El Portil to enjoy observing the scenery and birds from a platform offering panoramic views.
