Part of the Paraje Natural Marismas del Odiel, the Lagunas de Palos y las Madres covers 693 hectares and consists of four lagoons: La Jara, Las Madres, La Mujer and Palos. They are the remains of what once was a nearly continuous line of coastal lagoons linking the marismas at the Odiel-Tinto confluence and those at the Guadalquivir estuary.

Palos de la Frontera is predominantly an agricultural village due to its vast trade of local strawberries and raspberries. It is also well known for being where Christopher Columbus set sail eventually reaching America in 1492. It has about 8500 inhabitants.
