Lisbon --- how to reach sintra, cabo da roca?
St. George's castle--- Just walk upwards from Praca do comercio. You will reach it. Just follow the uphill ways.
Sintra- Take a train from Rossio or Sete Rios, directly goes to Sintra terminal. To reach the castles at the top, take Bus 434 (2009) , right out of the train station.
Cabo Da Roca- You find the bus at Sintra train station that goes to Cabo Da Roca.
Cascais- Take bus from Cabo da Roca.
Better planned visit thus is to go to Sintra from Lisbon, then to Cabo da roca and then to Cascais..If you start around 9 in the morning, you will finish all.
I visited Lisbon in July, 2009.
