Having a guide is an added benefit of skip the line. Our guide told us so many interesting things about the castle that we would never have known. Our daughter visited a few months ago without a guide and they didn't know much about the history of the castle. The guide gave us some interesting information then left for us to explore on our own.

Wonderful tour, guide was extremely knowledgeable and helpful in having understand and appreciate the history of the castle. As for the value, I gave the score (4 stars) based upon the amount charged and she was only with us for approximately 20-25 minutes.

We got a lot of interesting and important historical background information about the Castle of Lisbon from our well informed and friendly tour guide. He made the tour interactive by asking the group questions, which made the experience even better. The tour was roughly one hour long and we definitely recommend to book it, as visiting the castle without all that information would be rather boring.
