Explore beyond Lisbon's city limits - and see several of Portugal's top attractions in one day - on this seamless, small-group tour. Set off in the morning in an air-conditioned vehicle and head to UNESCO-listed Sintra. Skip the long lines and explore the Pena Palace (tickets at additional cost). Then pass by Cabo da Roca (the westernmost point of continental Europe) and Cascais on your way back to Lisbon.
