This half-day tour caters to passengers who want to see the sights of Lisbon, with little or no walking involved. Your first photo-stop is the unique Belem Tower, a lighthouse and fortress that sits on the banks of the Tagus River. View the nearby Monument to the Discoveries, an awe-inspiring stone structure, shaped like the prow of a ship and featuring statues of Portugal's great explorers. After some free time, drive past the 16th century Jeronimos Monastery, a magnificent Gothic building said to be the most important landmark in the city, then drive up the hill to the Alto do Parque Belvedere, a delightful open space that offers wonderful vistas of the city and harbor. You will also pass by the 25th of April Bridge, which offers distant views of the Christ the King statue. Enjoy free time downtown.
