A short drive south from Lisbon, the salt-scented air sharpens as the highway crosses the Tagus on the 25 de Abril Bridge and the city recedes. By the time the van reaches Setúbal’s working harbor, the river widens into the Sado Estuary and light fractures across shallow channels where bottlenose dolphins often forage close to shore.
