The Faro de Chipiona dominates the western end of the town — a tapering grey-and-white tower visible from miles up the coast and out at sea. The lighthouse keeper still gives tours on Saturday afternoons (and most days in summer); the climb up the 322 spiral steps to the lamp gallery is steep but the reward is one of the best coastal panoramas in southern Spain — Sanlúcar across the river mouth, Doñana on the northern bank, the salt flats of Cádiz Bay to the south.
