Hop aboard a fun and eco-friendly open tuk-tuk for a sightseeing tour around Porto. The vehicles are a tricycle of sorts, invented in Thailand and adapted to European requirements, including enhanced safety and comfort. They run totally silent and are customized with an electric, emission-free and environmentally friendly motor. Your one-hour panoramic ride through the town center is the ideal way to view the highlights of this ancient city that actually gave Portugal its name. Among the sites you'll see are some of the most iconic landmarks such as the Church of Clerigos, an 18th century Baroque and Rococo building whose 249-foot-tall tower is the tallest in Portugal; the Livraria Lello Bookstore where author JK Rowling wrote the first few chapters of 'Harry Potter and the Philosopher's Stone,' the Cathedral of Porto, built between the 12th and 13th centuries; and the beautiful 120-year-old Sao Bento railway station.
