We want to go to Quinta da Regaleira, Pena Palace and Park, and the Moors’ Castle, in one day trip from Lisbon. We somewhat understand the Sintra 434 bus. If we do Pena Palace and the Moors’ Castle first, from the Sintra train station where exactly do we get on the 434 bus and how do we get there from the train station? When we are done where do we get the 434 bus, how do we get to Quinta da Regaleira, and then how do we get back to the train station? If it is better to first go to Quinta da Regaleira how do we get there from the train station, and how do we get back to the 434 bus pickup location to go up to Pena Palace and Moors’ Castle?
