The town is divided into the older quarter, the Barrio Alto where most of the interesting sights can be seen and the newer Barrio Bajo, closer to the river. The Plaza del Cabildo is located in the heart of the old town, a delightful, palm-fringed square lined with bars and restaurants. Just north is the Plaza de San Roque where the daily market is held.

Sanlúcar beaches
are also magnificent and stretch several kilometers to the south-west, while the former port and fishing quarter, the Bajo de Guía is unsurprisingly where some of the best seafood restaurants can be found. You can catch the ferry from Playa Bajo de Guia over the river to the Parque Nacional de Doñana. This is a spectacle in the days leading up to Rocio when the pilgrims cross the river with their horses here at the end of the tree-lined Calzada del Ejército.
