Cascais and Boca do Inferno
Once a mere fishing village, the town of Cascais—with three small, sandy bays—is now a heavily developed resort packed with shops, restaurants, and hotels. Despite the masses of people, though, Cascais has retained some of its small-town character. This is most visible around the harbor, with its fishing boats and yachts, and in the old streets and squares off Largo 5 de Outubro, where you'll find lace shops, cafés, and eateries. The beaches are attractive, too; however, you must be mindful of pollution problems here. Unless signs indicate otherwise, stay out of the sea.
