Sintra

Sintra is the day tour to make during your visit to Lisbon. The village is well-known for its colorful castles. The way to go there is by public train and over there you can buy a combination ticket in which the entrance and transport between the castles are included. The most well-known castle is Palácio da Pena. But there are many other buildings to visit so this means that you need a full day.
