1. Wander Through Alfama’s Sunlit Alleyways
There’s no better time to explore Alfama, Lisbon’s oldest neighborhood, than on a bright May morning.

Stop for a pastel de nata, snap photos of traditional trams, and take your time discovering hidden courtyards and tiny Fado bars.
2. Soak Up Views at Miradouros (Viewpoints)
May’s sunny skies make Lisbon’s miradouros (viewpoints) irresistible. These hilltop spots offer panoramic views of the city’s red rooftops, the Tagus River, and the famous 25 de Abril Bridge.

Bring a bottle of wine, some snacks, and enjoy an open-air picnic as locals play music nearby.
3. Take a Tram 28 Ride Through the Sunlit Hills
The iconic Tram 28 offers a leisurely way to experience Lisbon’s charm, especially on a clear May day. This classic yellow tram winds its way through the most picturesque parts of the city, including Graça, Alfama, Baixa, and Estrela.
