Another must is the out-of-town visit to Sintra, a UNESCO World Heritage site less than half an hour from Lisbon. A lot of out-of-towners come here to take in the sights of the Moorish Castle and the National Palace of Sintra, just to name a few. This town is like a scene from a fairytale, and even with all the rain during the time of my visit, I couldn't help but feel like I was walking through the pages of a storybook. You can drive (though it can be really difficult to park and a bit congested) or take a train from Lisbon. Of course, the tour offers a comfortable coach and driver, so you don't have to worry about any of those details.
