If you go to Lisbon this summer you can also go to the beach, swim in the Atlantic Ocean and sunbath. Although Lisbon doesn’t have a beach there are some really close and the most famous of all is Costa Caparica.
Costa Caparica is about 40 minutes away from Lisbon by bus -you should get the bus at plaza España-. There are several beaches at Costa Caparica which are very popular at summer but not too crowded. And in the summer there’s a small train that makes several stops along the 10 km of beaches of Costa Caparica.
