Just across the Tagus River from the capital city of Lisbon, the Costa da Caparica begins. While an eponymous town can be found along this coveted stretch of coast, it's the miles of beaches that bring visitors in. You can find ample tourist amenities and facilities in the town of Costa da Caparica, which lends to the destination's popularity as a getaway hot spot. Summertime is when most when people flock to the Costa da Caparica beaches, and these beaches can get pretty crowded, thanks to their proximity to Lisbon. The further south you head, the more likely you are to find less crowded beaches, though these beaches can also be more liberal, and nudity is common at some of them.
