A fairytale town on the slopes of the Sintra Mountains, just an hour and a half by train from Porto if you travel to Lisbon first and then onward. However, the ideal day trip from Porto is visiting Sintra by bus or car — stunning palaces, the mysterious Quinta da Regaleira with its spiral well, and lush gardens make it an unforgettable experience. A UNESCO-protected site with unique 19th-century Romantic architecture.
