1. Praia dos Galapinhos, Parque Natural da Arrábida
It’s only an hour out of Lisbon but it feels like another country. This crescent of sand lapped by lapis lazuli water and backed by the forested hills of the Serra da Arrabida is accessed by what the locals call ‘the goat path’. But once there it’s totally worth. And the small beach kiosk will sell you everything you need for a day out.
