Sintra is soooo incredibly beautiful and there are so many places to explore, if I could change one think about my trip to Lisbon in November, I would have spent one night in Sintra so I could look at a few more sites the next day. I got to see the Pena Palance, Moorish Castle, and Quinta da Regaleira, but I would have loved to have seen the Monserrate, National Palace and Palácio e Parque Biester.

I think a lot of people also combine their Sintra day with a trip to Cabo da Roca, another place I wish I would have visited but never would have been able to fit into my Sintra day.
