Accessing the Parque Nacional de Doñana
Sanlúcar is a good base for exploring the Parque Nacional de Doñana, which glistens just across the Río Guadalquivir.
Trips are run by the licensed Visitas Doñana, whose boat, the Real Fernando, chugs up the river for wildlife viewing. Your first option is a 2½-hour boat/jeep combination (€35), which goes 30km through the park's dunes, marshlands and pine forests in 21-person 4WD vehicles, operated in conjunction with Cooperativa Marismas del Rocío, based in El Rocío, Huelva province. There are two trips in the morning and two in the afternoon March to September, and one daily trip November to February. The second (less interesting) option is a three-hour hop-on, hop-off ferry tour with a little walking (adult/child €17/9), which runs with the same frequency. Book at the Centro de Visitantes Fábrica de Hielo. Trips depart from Bajo de Guía; it's best to reserve a week ahead.
Viajes Doñana agency books the same trips, as well as 3½-hour tours (adult/child €40/24) with the Cooperativa Marismas del Rocío in 21-person 4WDs, which travel 70km into the park. Depending on demand, it can also arrange private five- to six-person jeep tours (€270 per jeep).
