We are going to be in Sintra this February and when looking at opening hours for the palace and other attractions it only list them until October 27th, does this mean they are closed for the winter months...if so is it worth taking a trip to Sintra? We were going to spend two nights. Thank you in advance!
Nothing closes in the winter, other than Christmas and New Year’s Day. I’m not certain why you are finding no opening hours at that time of the year. There might be the occasional restaurant taking a couple of weeks off, but nothing else. Sintra has become a year round destination. But, as you likely already know, be prepared for rainy and cool weather.
