Things to Do in Lisbon During March
Since there will be quite a few sunny days this month, you might want to consider taking a pay-what-you-wish walking tour in Lisbon.
If you happen to visit on a rainy day, consider heading indoors to see a live Fado music performance. Alternatively, you may also want to visit the National Tile Museum to see some of Lisbon's greatest art.
