Sintra Center, Quinta da Regaleira
A day in Sintra visiting the Quinta da Regaleira, the special occasions palace as I understand it (Warning: Parking can be hard to come by. The city bus stops nearby). The Iniciatic Well is quite a sight, and the underground cave system weaved through the palace grounds. Afterwards, a quick walk over to the main palace at the Sintra City Center, and a walk through the narrow cobblestone streets, with a notable visit to a porcelain store, very colourful (and breakable).
