Sanlúcar de Barrameda - Ferry to Doñana
You can catch the open ferry boats from Playa Bajo de Guia over the Guadalquivir river to the shores of Parque Nacional de Doñana (and back again). From here you can walk along the beach or walk a little way into the park, although there is not much to see at this point. Special permission is required to enter the park at this point in a motor vehicle.
