In Lisbon, travelers can use public transportation such as buses, trams, and metros to navigate the city. The cost of a single trip is around $2.50, and the travel time varies depending on the destination. For a more authentic experience, travelers can also take a tuk-tuk, one of Lisbon's most popular forms of transportation, which costs around $30 per hour and offers a unique perspective of the city.
If you have some extra time, consider visiting the National Azulejo Museum, a tribute to Portugal's famous vibrant tiles or take a short journey to the beautiful town of Sintra. If you have less time, consider skipping the Alfama district or replacing it with a visit to the Museu Nacional de Arte Antiga, which houses some of the country's most significant art collections. Make sure to wear comfortable shoes and carry a sun hat and water bottle to stay hydrated during the day.
