Sintra, the best place to be
There are a lot of places to visit in Sintra. And too many people all the time. It's really hard to see all the must-sees in Sintra in just one day. So it takes at least two days, I guess. When you know the Portuguese history, visiting palaces gets much more interesting. Here are the list of places in Sintra, I have visited so far. (1) Pena Castle and Park. Entrance fee: 14 euros. Garden only: 7.5 euros (2) Quinta da Regaleira Entrance fee: 8 euros (3) National Palace of Sintra Entrance fee: 10 euros (4) Monserrate Entrance fee: 8 euros (5) Queluz Palace Entrance fee: 10 euros. Garden only: 5 euros. My favorite is Quinta da Regaleira. Next year, they will raise the entrance fee again. They always do every two years. So if you are planning to visit Sintra, do so this year.
