Tram 28

Yes, it's a mode of transportation, but recent travelers say it's also an attraction in and of itself. For a small fee, you can ride Tram 28 to the top of the Alfama district, seeing city squares, red rooftops, the Sé Cathedral and finally ending at St. George's Castle. Some travelers recommend taking the tram up the steep hill and then walking back down to explore the neighborhood. Many travelers say that though the tram tends to be crowded, it's a must-do.
