One of the oldest cities in the world, Lisbon is an enchanting place—but let's face it, once you've seen the ceramic tiles, ridden the trams, and tasted the Pastéis de Belém, you might be ready to broaden your horizons. Portugal's treasures are well worth venturing beyond the capital city, and all you need is a rental car for the southern half of the country to open up to you. If it’s charming villages, stunning beaches, verdant mountains, and ancient castles you’re after, you'll find them all within a three hours' drive from Lisbon.
