How many days
One day covers the gardens and the exterior of the Marquis of Pombal’s palace and a walk along the seaside promenade. A second day takes you to the Vasco da Gama Aquarium in Algés and to the Barcarena Gunpowder Factory. Many people visit Oeiras from Lisbon or combine the town with Cascais.
When to go
The climate is Mediterranean with Atlantic influence: hot, dry summers and mild, rainy winters between November and March. The beaches fill up from June to September. In the shoulder seasons, the promenade and the gardens invite unhurried walks.
The seasons shown are the most usual ones; nature doesn't always follow the calendar.
Do you need a car?
Not essential. The Cascais line train stops near the palace, the promenade and the aquarium. A car or local transport helps to reach the Gunpowder Factory in Barcarena, inland in the municipality, about 6 km from Oeiras center.
