Lisbon Family-Friendly
Oceanarium, lifts and trams, Sintra's fairy-tale palaces and Belém custard tarts, a relaxed pace for families with kids
Planned with families in mind: on day one, ride the lifts and visit squares in the flat Lower Town. Day two is spent entirely in Parque das Nações, at the Oceanarium and along the riverside walk, then an afternoon tram up to the castle. Day three heads to Sintra to see the colorful Pena Palace. The final half-day is in Belém, for the tower and custard tarts, before heading to the airport. Stay in Lower Town, with few slopes and easy stroller access. Museums and nightlife are skipped.
The Oceanarium is indoors, so you can reorder days on hot or rainy days.
