From Alcácer do Sal, the minor EN253 follows the banks of the Sado estuary to the nearest stretch of coast at Comporta, 26km west. It’s a lovely drive and worth it, as the beach – signed just to the north of the village off the EN253-1 – is simply magnificent, a giant stretch of soft sands served by a couple of seasonal beach café-restaurants, though this may change if a planned tourist resort comes to fruition. You can continue up the EN253-1 onto the Tróia peninsula for the ferry back to Setúbal.
